摘要

钱塘江由于钱江潮而引起水位偏高，如何保证在高水位条件下基坑的边坡安全及施工方便成为基坑支护的一个难题。结合具体的工程实例，对钱塘江边的基坑工程进行了降水设计及水位监测，并对降水效果进行了分析。结果表明，针对钱塘江冲积平原的土层渗透系数大，采用自流式的深井进行降水是可行的，而且当钱塘江水位较高时可以采用截流深井进行综合降水处理。

Abstract

The Qiantang River has high water level because of the tidewater. It is difficult question for foundation pit how to guarantee slope safety and construction convenience on the condition of high water level. The dewafering design and monitoring methods of building foundation pit nearby the Qiantang River are carried out according to the engineering case. The effects of foundation pit dewafering. The results show the foundation pit dewafering is effective by means of deep well for the soil layers of large permeability coefficient. When the water level of the Qiantang River is high

it is necessary to lower the high water lever by use of cut-off well.
