Deep well dewatering of soft soil two-layer structure excavation is a kind of economical and effective dewatering method to ensure waterproof in deep excavation. Nevertheless its negative impact on is often unavoidable.
在软土地区二元结构地层，采用深井降低承压水，是保证深基坑施工作业的一种经济有效的方法，但也存在着一定的负面影响，因为降水势必会形成降水漏斗，而引起基坑周边地面沉降，可能导致周边建筑物和公共设施的开裂或损坏。
