摘要
浅层地表水和邻近河流补给、接近坑底的高渗透砂性土层内丰富的微承压水以及坑底下方的承压水,给深基坑工程施工期间的降水工作带来了不小的困难。苏州太阳广场项目针对此复杂的地质情况,采用上部深井疏干、下部轻型井点、坑外深井减压的组合降水方式,取得了较好效果,为同类型地质条件下的深基坑降水积累了经验。
There are lots of difficulties to therainfall during the deep foundation pit engineering construction period because of superficial surface water and neighboring rivers supplies,the abundant micro confined water in hypertonicity soil layer and the confined water nearby the bottom of the pit We apply the pattern,which combine the upper sewer drainage with the lower light well point in the Sun plaza of Suzhou.The integrated precipitation way have a good effect and accumulate the experience in the same type of the precipitation of the deep base pit.
