| 摘 要： | 地下水赋存状态与渗流条件的改变及其造成的土体中孔隙水压力的变化是造成岸坡失稳的重要因素。通过模型试验和数值计算（EMU法）检验了降水速率对岸坡稳定性的影响，初步验证了虹吸排水法能够减小岸坡内地下水与库水位之间的水位差，并改善渗流路径，为其在工程中的应用提供了依据。

| Abstract: | The pore water pressure will be altered with the changes of groundwater characteristic and seepage condition. It will be also a crucial factor to the bank slope instability. Based on the model experiment and the numerical simulation (EMU), they the influence of drainage velocity on the bank slope stability is verified. This test also validates that the siphon drainage technology can reduce the water head between the reservoir and groundwater in the bank slope and make seepage path better. The results will be useful in engineering practice. |
