Research on Effect of Drainage Measure to Giant Landslip Stability

The seepage module of GEO-SLOPE software is used to simulate the seepage field of Jinping Highway giant and old landslip after setting up the blind hole in Guizhou province. According to water level changes before and after setting up blind hole, by using stability analysis module to compare relevant parameters of landslip stability before and after drainage, the author shows that drainage is good for landslip stability.
