摘　　要：介绍了新疆某输水泵站工程的基本情况。根据泵站开挖出现的3个边坡裂隙发育情况,采用赤平投影法搜索出岩质边坡不稳定块体,考虑岩质边坡节理裂隙构造,采用楔形体稳定计算软件,计算了岩质边坡楔形体及上覆破碎岩体的稳定性,得出了楔形体及破碎岩体的稳定安全系数。通过计算分析,泵站周边坡在各个工况下整体稳定性较好,块体稳定及变形破坏问题不突出。根据计算结果,同时考虑工程安全储备,提出了岩质边坡的支护措施。An introduction was made on the general information of a water delivery pump station project in Xinjiang.According to the development of three slope fissures exposed after excavation,the unstable block of rock slope was searched by stereographic projection method.Taking into account the joint crack structure of rock slope,the stabili⁃ty coefficients of rock slope wedge and overlying fractured rock mass was calculated with wedge stability calculation software.The results of calculation and analysis demonstrate the surrounding slope of pump station is stable integral⁃ly under various operating conditions with stable block and without outstanding deformation problem.The support⁃ing measures for rock slope are proposed according to the calculation results while considering the engineering safe⁃ty reserve.
