【摘要】 边坡的稳定性分析是地质灾害防治中的一个重要内容。以雪浪山横山寺西侧顺层岩质高边坡为研究对象,运用离散单元法计算边坡在自重、暴雨和地震工况下的安全系数,并对其薄弱部位进行监测,分析其稳定性和破坏机理。结果表明:在暴雨和地震工况下,边坡产生拉张破坏,坡体产生较大位移。通过开挖放坡、锚杆(索)联合加固、在坡顶、坡脚及各级平台布设截、排水沟等治理措施后,边坡稳定性显著提高。通过测斜仪和裂缝计对治理后的边坡进行监测得出,边坡水平位移较小,裂缝的发展得到控制,边坡稳定性得到有效提高。更多还原

【Abstract】 Slope stability analysis is an important content in geological disaster prevention. the high bedding rock slope on the west side of Hengshan Temple in Xuelang Mountain is taken as the research object. The discrete element method is used to calculate the safety coefficient of the slope under the working conditions of dead weight, rainstorm and earthquake, and to monitor the weak parts to analyze its stability and failure mechanism. The results show that under the conditions of rainstorm and earthquake, the slope has tensile failure and large displacement. The stability of slope is improved by means of slope excavation, joint reinforcement of anchor bolt(cable), installation of cut and drainage ditch at the top, foot and platform of all levels. The slope after treatment is monitored by inclinometer and crack meter, and it is concluded that the horizontal displacement of slope is small, the development of crack is controlled, and the stability of slope is effectively improved.更多还原
