However, changes in the functional connectivity between the defauk mode network and insula during pain remain unclear. This study used 3.0 T functional magnetic resonance imaging scans in 12 healthy sub- jects aged 24.8 ± 3.3 years to compare the differences in the functional activity and connectivity of the insula and default mode network between the baseline and pain condition induced by intramuscular injection of hypertonic saline. Compared with the baseline, the insula was more functionally connected with the medial prefrontal and lateral temporal cortices, whereas there was lower connectivity with the posterior cingulate cortex, precuneus and inferior parietal lobule in the pain condition. In addition, compared with baseline, the anterior cingulate cortex exhibited greater connectivity with the posterior insula, but lower connectivity with the anterior insula, during the pain condition. These data indicate that experimental low back pain led to dysfunction in the connectivity between the insula and default mode network resulting from an impairment of the regions of the brain related to cognition and emotion, suggesting the impor- tance of the interaction between these regions in pain processing.展开更多

In order to improve the structural performance of urban high-rise buildings and effectively deal with the problems of foundation construction, the construction industry and its employees should strengthen the research work of pile foundation construction technology, provide guarantee for the smooth progress of high-rise building construction at the technical level, and provide support for improving the construction quality of building structures. This paper analyzes the construction technology of pile foundation, and puts forward personal views on how to further guarantee the construction quality of pile foundation, so as to provide reference for those who are concerned about construction engineering and pile foundation construction technology.展开更多

Nowadays, with the continuous development of building construction in China towards more beautiful and more floors, ensuring the quality of foundation has become the primary factor. Foundation construction is not only the first step of construction engineering, but also the key step. In order to ensure the quality of foundation construction and avoid building inclination or settlement caused by foundation problems, it is necessary to strictly grasp the quality links and ensure that the construction is completed in accordance with relevant standards. The application of foundation detection technology can ensure that the foundation quality meets the requirements of construction engineering and fundamentally improve the overall quality of construction engineering. Therefore, the application of foundation detection technology in construction engineering is of great significance. In this paper, the author deeply analyzes the key points of foundation detection technology of construction engineering and gives corresponding optimization countermeasures for reference to relevant construction units展开更多

With the continuous increase of water conservancy construction projects, most of the projects are built on soft soil foundation, which has a negative impact on the overall quality and safety of the project. In order to effectively improve its bearing capacity, it is necessary to adopt soft soil foundation treatment technology, improve the quality of the foundation, reduce the safety risk in the construction, and promote the smooth construction of the project. Based on this, this paper briefly analyzes the harm of soft soil foundation in the construction of water conservancy projects, and then explores the application points and treatment technologies of soft soil foundation in detail, in order to promote the sustainable development of water conservancy industry.展开更多

The strength and bearing capacity of the foundation can guarantee the stability of the building structure. In the construction of building engineering, the relevant construction units should pay attention to the foundation construction link and also have a comprehensive understanding and grasp of the advantages and disadvantages of the foundation construction technology, so as to select the technology suitable for the foundation construction requirements. According to the actual situation of the foundation construction and the foundation construction demand and effectively apply it to the foundation construction process, it avoids the foundation from going out the current problems affect the overall quality of construction projects.展开更多

Therefore, the construction quality of soft foundation is an important factor affecting the quality of highway bridge engineering in our country. Soft foundation is an important potential safety hazard in highway and bridge construction. Its water content is above 70%, and it has low foundation bearing capacity, permeability, compressibility, viscosity and other characteristics. If not paid attention to in the construction process, it will not only affect the overall use effect of the project, but also cause uneven settlement, instability, collapse and other problems, causing serious consequences. Therefore, it is necessary to adopt appropriate technical measures in highway, bridge and other projects. Therefore, in highway bridge construction, technical personnel should strengthen the control of the soft soil foundation in time, understand the influence of the current soft soil foundation on the bridge structure from the perspective of soft soil foundation treatment, fully understand the engineering requirements, and master the technical key points of construction at the same time, improve the construction treatment technology of the soft soil foundation of the road bridge, and guarantee the construction quality. In order to further improve the quality of highway and bridge construction, the feasibility analysis scheme of soft foundation reinforcement technology is formulated. Based on the characteristics of soft foundation and the problems in construction technology, this paper discusses its specific application.展开更多
