Experimental Research on the Soft Foundation of Culvert Treated with Vacuum Preloading in Combination with Heaped-Load Preloading
-
摘要: 以广珠准高速铁路软土路堤试验真空预压联合堆载预压处理涵洞软基的测试结果为例,对用该方法处理软基的沉降与纯堆载预压处理的效果对比、处理前后的物理力学性质指标对比、涵基的变形等方面进行了分析。Abstract: Taking the results of the test on the soft foundation of culvert treated with vacuum preloading in combination with heaped-load preloading on the Guangzhou-Zhuhai Qusai-High-speed Railway for example, analyzing settlement of the soft foundation, comparing the results with that of sole heaped-load preloading, comparing the physical and mechanical parameters after being treated and before, and studying the deformation of the soft foundation of culvert, etc.
