| 摘 要： | 为验证坝基土体三维渗透模拟试验装置的渗透性能，以白城市待建水库选址工程为依托，采集土样进行室内渗透模拟试验，获得试验水压等势图，分析水库坝基的渗透特性。同时运用有限元软件对试验装置的稳定渗流进行数值模拟。模拟水压等势图与试验水压等势图大致相同，证明了装置渗透性能是科学可靠的。试验现象表明此处土层不宜作为坝基选址。

| Abstract: | In order to verify that the simulation test device for soil dam foundation of three dimensional seep-age clogging has good permeability ,taking the project of a reservoir in Baicheng as the backing ,the soil sam-ple is collected to carry out the simulation test ,and the water pressure is obtained.At the same time ,the finite element software is used to simulate the steady flow of the test device.The simulation and test of hydraulic pressure potential map roughly the same ,proved that the device permeability is scientific and reliable.The test phenomenon proved that the soil should not be taken as the location of dam foundation. |
