The environment provides the necessary resources and conditions for our livelihood and development. With the development of social economy, environmental problems have been put on the agenda of relevant departments of various countries as an unavoidable and important issue. Protecting the environment, reducing environmental pollution and curbing the trend of ecological deterioration have become an important task of social management of relevant departments. For China, environmental protection is a basic national policy. It is an important and arduous task to solve the prominent environmental problems in the country, promote the coordinated development of economy, society and environment and implement the sustainable development strategy. China ecological and environmental protection association pointed out that we must not follow the old path of "pollution before management" in western countries, but should put environmental protection in an important position in advance. For civil construction, the waste of tunnel slag is one of the important factors affecting soil and water conservation in mountainous areas. Reasonable digestion and utilization of tunnel slag is one of the important measures to protect the ecological environment in mountainous areas. 展开更多
