上海软土地区深基坑工程的环境影响因素分析

A Research of Environmental Influencing Factors for Deep Foundation Pit Projects in Soft Soil Area in Shanghai

上海地区的地下工程建设在向"深、大、近、难、险"的方向发展,而本地区的工程地质条件决定了深基坑工程建设无法避免对环境产生不利影响。结合日常深基坑评审工作和大量事故处理工作,对基坑施工过程中容易造成环境影响的常见因素进行了辨识和归纳。同时,在管理环节提出建议,希望通过加强管理,将基坑工程施工过程中对环境的影响降到最低。

At present,five adjectives,deep,large,close,difficult & risk,can describe the trend of underground engineering construction develop-ment in Shanghai area.The deep foundation pit projects cannot avoid negative influences on the surroundings determined by the regional geological conditions.Combined with daily deep foundation pits review works and a large amount of accidents management examples,the regular influencing factors during the construction period are identified and summarized.In the meantime,some suggestions are proposed to focus on the management and to lower the environmental influence as far as possible.
