钻孔压水试验是探求水工建筑物基础岩体渗透性的主要方法,过去一直是采用三个压力点来进行试验的。近年来,许多单位已逐渐采用一个压力点(S>1米水柱)进行压水试验。实践证明,采用这种试验方法,其单位吸水量ω值常存在着因不考虑实际渗流 Drilling water pressure test is the main method to find the permeability of hydraulic rock mass foundation. In the past, three pressure points were used to test. In recent years, many units have gradually adopted a pressure test (S> 1 m water column) for water pressure test. Practice has proved that the use of this test method, the unit value of water absorption ω often exist due to not consider the actual seepage
