摘要
煤矿开采过程中,覆盖在煤矿表面的渣石作为工业废弃物无法得到有效利用。文章通过室内模型和有限元分析,研究煤矿渣石和土工格室在软土路基中的应用,通过荷载沉降变化、土工格室层横向变形和路基土压力变化情况评价煤矿渣石和土工格室的应用可行性。结果表明:煤矿渣石和土工格室可以降低路堤最大沉降值和路面荷载传递,减小路基土压力,同时提高土体压实度和稳定性,限制土体侧向变形。
In the process of coal mining,the slag covering the surface of the coal mine cannot be effectively used as industrial waste.The application of coal slag and geocell in soft soil subgrade is studied through the indoor model and finite element analysis,and the application feasibility of coal slag and geocell is evaluated through the load settlement changes,lateral deformation of geocell layer and subgrade earth pressure changes.The results show that:the coal slag and geocell can reduce the maximum settlement value of the embankment and the transfer of pavement load,reduce the subgrade earth pressure,and meanwhile improve the soil compaction and stability,and limit the lateral deformation of the soil.
