将强度折减技术与极限分析上限定理结合,利用安全系数Fs评定指标对层状岩体边坡进行稳定性上限分析,与已有研究成果进行了对比分析,并较为详细地分析了相关参数对层状岩体坡体安全系数和潜在破裂面的影响。分析结果表明,与同类计算方法的对比可以证明表明文中方法的正确性;边坡安全系数和破坏范围受边坡坡度、岩体重度、边坡高度、动载效应系数和岩层倾角的控制;当岩层倾角处于一定范围时,层状岩体边坡发生顺层失稳的可能性最大,工程中需特别注意。
Combining the strength reduction technique with the upper bound theorem of limit analysis, the stability upper limit analysis of stratified rock mass slope is carried out by using the safety factor Fs evaluation index, and compared with the existing research results. The relative parameter pairs are analyzed in detail Influence of safety factor and potential rupture surface of layered rock mass slope. The analysis results show that the comparison with other methods can prove the correctness of the method. The slope safety factor and failure range are controlled by slope slope, rock mass weight, slope height, dynamic load effect coefficient and rock dip. When the dip angle of rock strata is in a certain range, it is most likely that the stratified rock mass slope instability occurs along the strata, so special attention should be paid in the project.
