摘要
分级堆载预压法加固料场软基是一种有效的地基处理方法 ,为确定各级堆载时间和高度,计算软基强度及固结度,保证料场软基的稳定与堆载的安全,对堆载分期软基场地进行详细的测试试验与监测是必要的。文章结合上海梅山钢铁公司二期料场软基处理工程,对堆载试验区的测试试验与监测成果进行了分析,结果表明,采用砂石桩加砂石垫层作排水路径并结合分级堆载预压法加固料场软弱地基具有良好的效果。
It is an effective method to improve soft foundation of stockyard by preloading. In order to determine the stepped loading time and height, calculate the strength and the degree of consolidation of soft foundation and ensure the stability and security, the detailed test and monitoring are necessary. A case of applying thepreloading technique to treat soft foundation of stockyard of Shanghai Meishan steel company through the analysis on the test and monitoring data, the result shows that the good effect can be soft foundation treated by preloading combined with sand pile and sand cushion drains. is introduced, gained on the
