摘要
以某站台土质边坡为研究对象,对边坡外观质量、土体密实度、边坡尺寸等进行现场检测,在考虑站台改造、荷载增加工况下,分别采用圆弧滑动法、毕肖普法和简布法对该边坡最不利截面进行稳定性分析研究。结果表明:坡面存在抹面砂浆开裂、空鼓等缺陷,边坡内土体密实度较好,加高改造方案会使站台边坡处于不稳定状态,需要在改造前对边坡进行加固,毕肖普法适用于一般土质边坡稳定性问题的计算分析。
Taking a platform soil slope as the research object,this study conducted an in-situ testing on the slope's surface appearance quality,soil compactness,and slope dimensions.Under the condition of increased load due to platform renovation,the stability analysis of the most critical cross-section of the slope was performed using the Circular Slip Method,Bishop's Method,and Janbu's Method.The results show that:defects such as cracking and hollowing exist in the surface mortar layer;the soil compactness within the slope is relatively better.The heightening renovation plan would make the platform slope unstable,requiring reinforcement before modification.Bishop's Method is applicable to stability analysis of general soil slopes.
