| Abstract: | With the analysis of several key factors that affect the improvement result of soft soil improved with the vacuum preloading method,it is believed that modification of jet pumps for vacuum preloading,improvement of the air-tightness around the improved area,application of loads on sealing membrane,and shortening of the spacing of prefabricated drains are the main approaches to effectively improve the degree of consolidation of soil,shorten the working period and cut down the construction cost. |
