摘要
在基坑深井井点降水工程中 ,经常利用经验值确定渗透系数 ,设计降水工程方案 ,但往往与实际情况不符 ,可在施工现场利用降水井做抽水试验 ,重新确定渗透系数 ,修改降水工程方案 ,以便达到降水目的 。
The permeability coefficeint used to design the dewatering scheme is often estimated with empirical value and does not agree with the real conditions.It is suggested that the dewatering well should be used to do the water pumping experiment to determine the permeability coefficient.In this way,the previous dewatering scheme can be modified and the success of project can be guaranteed.
