Therefore, the normal operation of transmission line is a key link to ensure high-quality power supply service. Due to the wide range of transmission line erection, the erection site is mainly in urban areas with complex environment, and the insulation level is lower than the transmission network, resulting in high failure rate, heavy maintenance workload and more power outages caused by maintenance. In order to ensure the reliability demand of users, improve the satisfaction of users, and reduce the power failure caused by maintenance and fault, live working technology is proposed and applied to practical production. Live working is a kind of operation mode for inspection and maintenance under the condition of keeping all equipment of power grid without power failure. At present, most of the maintenance work and accident handling work in the transmission line can be completed under the condition of live operation. Therefore, the implementation of live operation can significantly reduce the power outage duration and power outage times of users and improve the reliability of power supply.展开更多

Therefore, we must strengthen the environmental protection and maintain the ecological environment in an all-round way. In the process of carrying out environmental protection work, the most indispensable and important component is environmental testing, which plays a multifaceted role. It not only plays an important role in environmental protection, but also plays an important and positive role in economic environment and people's health. With the deterioration of environmental problems, the role of environmental testing is more prominent. Environmental testing is a new research science with obvious comprehensive advantages and rich scientific contents. This is a very important driving force in the process of urban economic development. Relevant departments should pay more attention to environmental testing. From the actual point of view, appropriate and effective environmental protection measures should be taken to protect the ecological environment and promote the harmonious coexistence of man and nature.展开更多

The performance of the transmission antenna directly affects whether the transmission system can work normally. Based on this, it is necessary to strengthen the exploration of medium wave broadcasting transmission in the future work process, clarify its working principle, and strengthen the daily maintenance of medium wave broadcasting transmission. At present, the key parameters considered in the MW broadcast antenna include high elevation radiation, antenna efficiency, etc. This paper studies and analyzes the lightning protection measures of the medium wave broadcasting station for reference.展开更多

It points out that for buildings over the coal pillar, it is ad- visable to soften the intermediate ground of buildings when they are affected by mining. For buildings over the goaf, it is preferable to soften the ground at both ends of buildings. In order to enhance the ability of a building to resist tensile deformation, the key measure is to reinforce the bottom foundation of the building. In addition, the concept of “angle of break of building” is proposed. It is because of this angle that the protecting coal pillar is left, which is a better solution than prevailing solutions The findings provide a more scientific basis for mining under buildings.展开更多

The rockfalls along the limestone slopes were caused by unfavorable characteristics of the rock mass, weathering in combination with heavy rainfall and artificial influences during highway construction. Rockfall protection projects were conducted to protect human lives and facilities from future rockfalls. The rockfall protection program started with rockfall hazard analyses to identify the potential of rockfalls to occur and the potential consequences. At the locations of hazards where related risks were determined, detailed field investigations were conducted. Based on the indentified characteristics of potentially unstable rock masses, analyses of movement and resulting pathways were conducted. The trajectories, impact energy and the height of bouncing are dependent on slope geometry, slope surface roughness and rockfall block characteristics. Two protection measure approaches were adopted： prevention of rockfalls by removing potentially unstable rock mass or installation of rock mass support systems and suspending running rockfall masses with rockfall protection barriers. In this paper, rockfall hazard determination, rockfall analyses and rockfall protection designs for rockfall protection systems at selected locations on the limestone slopes along the Adriatic coast of Croatia are presented.展开更多

While the development of urbanization has made great achievements, we should also see that the problem of urban environmental protection has been gradually highlighted. Urban sewage treatment is one of the important contents of urban environmental protection, and some cities are eager to achieve success in their development, focusing on economic development, ignoring the impact of urban sewage discharge on the environment, and their actual management has been gradually diluted, which has brought greater harm to urban environmental protection projects. Therefore, we should put the urban sewage treatment work in the important position of environmental protection, and use the appropriate strategy to speed up the improvement, so as to make the urban development better.展开更多

The development of computer network technology has promoted the progress of big data technology, which has been applied to many fields and delivered very good results. The computer network information security is closely related to the application effectiveness of big data. However, the computer network information is extremely vulnerable to the influence of various external factors, which will not only lead to information leakage, but also cause serious economic losses. In order to effectively solve the problems above, the most important thing is to improve people’s awareness of protecting their computer network information from all aspects, and to develop prevention programs based on the actual situation, thus fundamentally ensuring the security and accuracy of network information.展开更多

This article used the contingent valuation method to find the willingness to pay for the protective measures and investigated the factors that influence the willingness to pay. Methods A cross-sectional face-to-face household survey was completed by 637 urban long-term residents and 591 rural long-term residents aged 15-79 in Beijing, China. Binary logistic regression was used to identify factors that influenced the payment rate or payment amount for the protective measures, including independent variables for district, gender, age, education, income, air conditioner ownership, heat wave experience, and chronic non-communicable disease. Results The payment rate was 41.1% for protective measures provided by the government and 39.5% by measures provided by the market. Most of the respondents were willing to pay 40 CNY per capita annually for measures provided by the government or the market. The factors influencing willingness to pay were district, gender, income, air conditioner ownership, heat wave experience, and chronic non-communicable disease. Conclusion Protective measures for heat waves need to be provided immediately. More attention should be paid to the situation of vulnerable groups, such as people who live in urban areas, those without air conditioning, and those who have experienced a heat wave in the past.展开更多
