摘要
垃圾的成分复杂且垃圾土强度参数严重不均一,致使垃圾堆体边坡物理力学性质差别巨大。利用对垃圾土堆体的几何和内摩擦角、内聚力、容重等参数分析处理后获得的数据建立垃圾土堆体边坡稳定性分析模型,基于简化毕肖普法分析影响因素对边坡稳定性影响度大小,获得影响因素对边坡稳定性影响度比较结果(边坡比>内摩擦角>内聚力>边坡高度>容重),为预防边坡失稳塌滑技术措施提供参考依据。
The composition of waste was complex and the strength parameters of waste soil were seriously uneven,which made a huge difference of physical and mechanical properties of waste mound slope.The slope stability analysis model of waste mound was established by using the data obtained from the analysis and treatment of geometry,internal friction angle,cohesion,bulk density,and other parameters of waste mounds.The influence degree of influence factors on slope stability was analyzed based on Bishop method,and the comparative results were obtained(slope ratio>internal friction angle>cohesion>slope height>bulk density),which could provide reference frame for the technical measures to prevent the slope from instability slipping.
