Experimental Research on the Soft Foundation of Culvert Treated with Vacuum Preloading in Combination with Heaped-Load Preloading

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.
