科学合理地确定基坑排水量,是管理部门合理合法征收疏干排水项目的水资源费的依据。文章通过分析项目区域内的水文地质条件,确定地下水类型,利用抽水试验数据,估算丽都公寓项目基坑排水量。在无法实现计量的情况下,利用试验井的抽水试验资料计算水文地质参数,再计算出项目的起步排水量,进而估算项目整个排水期排水量的方法是可行的。
Scientifically and rationally determining the displacement of foundation pit is the basis for reasonable and lawful collection of the water resources fee by the management department for drainage and drainage projects. By analyzing the hydrogeological conditions in the project area, determining the type of groundwater and using the pumping test data to estimate the displacement of foundation pit in Lido Apartment Project. When it is impossible to measure, it is feasible to calculate the hydrogeological parameters by using the pumping test data of the pilot well and then calculate the initial displacement of the project and then estimate the displacement of the project during the whole drainage period.
