Failure Analysis of Bedding Soft Rock Slope Under Rain Softening

分析了顺层软岩边坡发生溃屈破坏机制及过程,引用相关理论力学模型,并考虑了雨水软化作用的影响,得到了顺层软岩边坡发生溃屈破坏的边坡极限高度简化计算公式。论文以某园区边坡为工程实例,计算顺层软岩边坡在天然及雨水软化工况下的边坡极限高度,结果表明,雨水软化作用对边坡极限高度有巨大影响,研究成果对类似建筑边坡工程设计有一定参考价值。

In this paper, the mechanism and process of collapse failure of bedding soft rock slope are analyzed, and a simplified formula for calculating the ultimate height of collapse failure of bedding soft rock slope is obtained by referring to the relevant theoretical mechanical model and considering the effect of rain softening. Taking the slope of a park as an example, this paper calculates the ultimate height of the bedding soft rock slope under natural and rainwater softening conditions. The results show that rainwater softening has a great influence on the ultimate height of the slope. The research results have a certain reference value for similar construction slope engineering design.
