摘要
福州地铁X站基坑的围护结构出现涌水,这是一种比较常见的问题,基坑处于两种软硬不同的地层中,给基坑开挖和结构施工均带来一定的影响。这种施工地质环境被称之为复合地层,目前工程界针对盾构施工的复合地层研究颇多,但对基坑工程所遇的复合地层影响研究较少,故根据工程实例对复合地层给基坑施工带来的影响做一些判断和分析。
This is a common problem. The foundation pit is in two different hard and soft strata,which will bring some impacts to excavation and structure construction of the foundation pit. This kind of construction geological environment is called compound stratum. At present,there are many researches on the compound stratum for the shield construction in the engineering field,but there are few researches on the influence of the complex strata encountered in the excavation engineering. Therefore,according to the engineering example,impact of pit construction to do some judgments and analysis.
