Study On Human Environment Effect Of Tunnel Portal Project And Application

The problems in environment that people depend on for existence are being paid more and more attention. The construction of tunnel project, which is one of the key projects in highway or railway, also brings a series of environmental problems. In this paper, The systematic classification of the environmental problems caused by the construction of tunnel portal is carried out, and the causal relationship between the environmental problem and its effect is figured out firstly. Then this paper gives general requirements in the environmental effects of project factors, And puts forward a practical prevention and control measures secondly. In the construction of Renziding tunnel, which belongs to Wuzhou to Liuzhou highway, the application achieved good social and economic benefits. The content of this paper are as follows:The classification of environmental problems, the countermeasures of environmental effects, the environmental laws and regulations—from these three aspects, present situation of the research on human environmental effects resulting from the tunnel portal project in China and abroad are summarized. Four problems in the study on human environmental effects of the tunnel portal are proposed, and the human environmental effects and the tunnel portal engineering are summarized in detail.According to the environmental factors form, the environmental problem of the tunnel entrance is classified, and the environmental effects of the construction of the tunnel entrance is put forward. As far as the overall guidance and the specific implementation are concerned, a reasonable solution is put forward.Combined with the Renziding tunnel in Wuliu highway, initial environmental protection measures which was developed by the design and construction company are optimized. The application has achieved good social and economic and environmental benefits.It is worth mentioning that this paper systematically classifies the environmental problems in the tunnel portal, and puts forward the concept of environmental effects. At the same time, the environmental protection scheme is given.
