摘要
为确保南水北调中线工程总干渠在穿越掏砂洞时能够安全稳定的运行,对掏砂洞进行了灌浆处理。基于现场勘察试验资料,采用三维有限元对代表性渠段在多种工况下进行应力与变形计算分析。结果表明:经过水泥黏土浆灌浆处理后,总干渠护砌在穿越掏砂洞上方时,应力与变形均满足设计要求。
In order to ensure the safe and stable operation of crossing the dig sand hole of the main canal of South-to-North Water Diversion Middle Route Project, the grouting treatment measures were taken to deal with dig sand hole. Based on field survey test data, by three dimensional finite element method, stress and deformation of representative channel sections in a variety of conditions were computed and analyzed. The results show that, after cement clay slurry grouting treatment, the stress and deformation of main canal embankment across dig sand holes meet the design requirements.
