摘要
针对某露天边坡开挖过程出现数次滑坡的情况,根据坡体地质构造、地层岩性和水文地质等条件,运用极限平衡法及有限元强度折减法,对锚杆、预应力长锚索、格构梁和压力灌浆为主、结合坡面防护等辅助措施的加固方案进行了分析计算,验证了工程治理措施的加固效果,保证了坡体的稳定。
Based on problem on landslide occurred over serval times in a open-pit mine, slope consolidation scheme, which anchor bar, pressure grouting, lattice beam, long prestressed anchor bar are useed as main consolidation method and conbined with other auxiliary measures such as slope protection, are analyzed and calculated by using Limit Equilibrium Method and Strength Reduction FEM. As a result, slope consolidation result and engineering control measures are verified and ensuring stability of slope.
