Tube wells lowering water using in foundation with fine sand soils

井群降水的最大特点是降水面积大．可以在建筑物较密集的区域内降水、同时可以严格的监测．控制出水含砂量．防止周围由于含砂量超标准、产生建筑物的不均匀下沉。

The authors introduce the characteristics of tube wells dropping water and present the arrangement of wells and the schemes of dropping water for buildings.
