| 摘 要： | 大口径管井降水方法是应用较为广泛的、成熟的地下水控制措施。但因施工准入门槛低，在土建施工造价中所占比重较小，往往得不到重视，常出现边坡失稳、底板隆起等重大损失。基于抽水试验成果完成方案设计，抓准施工质量关键点是实现良好降水效果的必要条件。

| Abstract: | As one of groundwater control measures, the lager diameter tube well dewatering is applied widely and ma turely. Because of the low criteria of construction admittance, and the little proportion in the construction cost, quality control is often ignored. It causes slope instability and bottom plate uplift frequently. It＇s necessary to design based on hydrological pa- rameters from pumping test, control construction quality strictly for achieving satisfied effect. |
