咸阳北塬边垃圾土边坡稳定性分析

Stability Analysis of the Garbage Soil Slope in the Plateau North Side of Xianyang

目的垃圾土边坡作为建筑边坡的治理和利用存在不少难点。以咸阳北塬边垃圾土边坡为例,详细分析了垃圾土稳定性影响因素。方法结合该垃圾土(建筑垃圾和生活垃圾)的物质成分及结构特性,在现场静力触探试验、反算及专家经验等综合分析的基础上,确定了垃圾土的抗剪强度参数。结果采用极限平衡法计算出该垃圾边坡稳定性系数,该稳定性系数与目前该边坡的实际状况基本一致。结论提出了垃圾土边坡稳定性分析方法和失稳后的治理方案,它对下部建筑群的抗滑建设具有重要的指导意义。

For the garbage soil slope acted as treatment and utilization of the construction slope, there is many difficulties. The paper set the Northern Plateau Xianyang soil slope side of the garbage as an example, analyzes some influenced factors of the stability of the garbage soil in detail. In conjunction with the garbage soil （ construction waste and solid waste） material composition and structural properties, in the field cone penetration tests, the anti - balance and experience of experts based on a comprehensive analysis to determine the soil shear spam strength parameters. Results Limit equilibrium method used to calculate the stability of the slope coefficient of garbage, the stability of the slope coefficient and the current actual situation of basically the same. Conclusion Proposed garbage soil slope stability analysis methods and the management of instability after the program, which the lower part of the anti - slide construction of buildings of great guiding significance.
