地下工程中的环境岩土工程问题

随着城市人口的急剧增长,交通与住房拥挤状况日趋突出,在我国一些大中城市中,道路交通隧道、地铁工程、地下商城等地下工程建设项目在逐年增多。在其施工过程中经常出现基坑失稳、地面沉降、岩溶塌陷、洞室失稳、巷道突水等多种环境岩土工程问题,不仅严重影响地下工程建设和周围建筑物环境安全,而且给国家造成重大经济损失。本文针对地下工程建设的实际情况,探讨地下工程环境岩土工程问题。

Geoenvironmental Engineering Problems in the Underground Engineering

With the rapid urban population growth,traffic and crowded housing conditions become increasingly prominent,in a number of large and medium cities in China,road traffic tunnel,subway,underground shopping centers and other underground construction projects are increasing year by year.In the construction process,there are environmental geotechnical problems of pit instability,surface subsidence,karst collapse,cave instability,roadway inrush which not only seriously affect the underground construction and environmental security around the buildings,but also cause significant economic losses to our country.In this paper,based on the actual situation of underground construction,underground environmental geotechnical problems are discussed.
