摘要： 三峡库区蓄水后，由于移民建设用地需要形成了不少高切坡,绝大多数高切坡存在安全隐患，严重威胁新建城镇基础设施、建构筑物和人民生命财产安全。现以巫山县城东北部龙门大桥东端高切坡为例，采用极限平衡法及工程地质类比法对其稳定性进行了计算分析和预测评价。该高切坡采用“削坡+混凝土格构支护+挂网喷锚支护+毛石混凝土挡土墙+排水工程”组合措施进行了工程治理。

Abstract: Due to the demanding of the lands for the Three Gorger Reservoir immigrants after the reservoir impounding, numerous high cut slopes have been formed. Many of these high cut slopes have potential safety hazards and might threaten the infrastructures, buildings and even life of the newly formed towns. This paper presents a case study of the stability evaluation of a highcut slope at the east end of the Longmen Bridge, which is located at the northeast of City of Wushan County. This slope was remediated with a combination of several engineering slope stability mitigation measures: cut slope + reinforced concrete grid protection + anchored wire mesh with shotcrete + stone masonry retaining wall + engineered drainages. The stability and the safety forecast of this slope are analyzed by using both limit equilibrium and the engineering analog methods.
