摘要
渗透系数是工程降水设计中必须的重要参数。但是,由于水文地质条件的复杂性和计算方法的多样性,致使渗透系数的测试与计算往往存在着较大的差异。以杭州地铁工程某完整井抽水试验为例,通过自制的自动水位采集系统,对抽水试验结果进行了多种方法对比计算分析,为工程设计提供重要参考。
The coefficient of permeability is one of the most important hydrological parameters for the dewatering design. Due to the complexity and diversity for the site hydrogeology, the result of the coefficient of permeability might be greatly different. Based on the pumping tests in the geotechnieal investigation of Hangzhou Subway project, different methods of obtaining the coefficient of permeability have been used in the interpretation of the in-situ testing results with data collected by the in-house made automatic data acquisition system.
