摘　　要：针对强降雨条件下高速公路土质路堑边坡容易失稳的问题,运用Geo-studio软件对杭新景高速公路七里连接线某路堑边坡设置虹吸排水措施前后两种工况下的稳定性进行计算分析,并对不同位置设置虹吸的效果进行了比选;得到在同等降雨强度下设置虹吸边坡排水设施能够大大提高土质边坡的稳定性,同时还发现虹吸在边坡中位置的不同对排水效果影响较大。虹吸排水方法对于提高土质路堑边坡稳定性效果良好,值得应用推广。The highway soil cutting slope is easy to lose stability under the condition of heavy rainfall. For this,the stability of Hangxinjing highway Qili connecting line is analyzed with and without setting the siphon drainage measures by use of Geostudio software. Meanwhile,the comparisons of effects of siphon drainage measure at different positions are made. The results indicate that the siphon drainage measure could enhance the stability of slope under the same heavy rainfall condition and the difference of siphon drainage sites have a great impact for drainage effect. That means the Siphon drainage measures have good effect on improving soil cutting slope stability,and it＇ s suggested to be promoted.
