通过工程实例数据，运用模拟手段研究在基坑内降水的同时增加止水帷幕长度并超出降水井过滤器底部一定深度，形成悬挂隔水帷幕时对地表沉降及周边环境的影响。结果表明：随悬挂隔水帷幕长度的增加，坑内总涌水量显著降低，地表沉降量渐小。研究结果对实际工程具有较好地参考借鉴作用。
通過工程實例數據，運用模擬手段研究在基坑內降水的同時增加止水帷幕長度併超齣降水井過濾器底部一定深度，形成懸掛隔水帷幕時對地錶沉降及週邊環境的影響。結果錶明：隨懸掛隔水帷幕長度的增加，坑內總湧水量顯著降低，地錶沉降量漸小。研究結果對實際工程具有較好地參攷藉鑒作用。

Based on the data of engineering examples,this paper,by simulation,studies the influence of dewatering on ground surface settlement and surrounding environment,when the water stop curtain length increases and exceeds a certain depth of the bottom of the filter of the precipitation well until a suspended waterproof curtain comes into being.The results show that with the increase of the length of suspended waterproof curtain,the total pit yield decreases significantly and surface settlement reduces stably.The results shed light on practical engineering.
