摘要
为了研究湿陷性黄地基排土场的稳定性,利用极限平衡法评价各种工况条件下的排土场边坡的稳定性,进行基础工程地质勘查,构建地质概化模型,根据室内外试验结果选取排土料及地基岩体强度的物理力学参数,并辅以余推力法进行验证。分析了袁家村排土场边坡现状及最终边坡的稳定性,结果表明:该排土场稳定性安全系数满足要求。
In order to study the stability of collapsible yellow foundation dump, the article uses limit equilibrium method to evaluate the stability of the dump slope under various working conditions. We carry out basic engineering geological exploration, construct the geological generalization model. According to indoor and outdoor test results, we select the physical and mechanical parameters of the discharge material and the strength of the foundation rock mass, verify the residual thrust method. The article analyzes the current situation of the slope of Yuanjiacun dump and the stability of the final slope. The results show that the stability safety factor of the dump meets the requirements.
