摘要

根据倒虹吸基坑降水实际效果,总结了不同地质情况下的基坑降水方法.比较了截渗墙与管井降水方案,考虑施工要求及降水方案造价,选择管井降水方案.降压采用压力平衡法计算,抽水量采用流量法计算.
Based on the actual dewatering effect of the inverted siphon foundation pit,dewatering methods of the foundation pit under different geological conditions were summarized.Comparing the dewatering schemes of cut-off wall and tube well,the tube well dewatering scheme was selected in view of the construction requirements and the dewatering costs.The pressure balance method was adopted to calculate the pressure decrease and the discharge method to the pumpage.
