摘要
本文针对淮河入江水道运河西堤崇湾段深层淤土软弱地基承载力差的特点,通过变真空预压法与传统真空预压法现场试验区的监测与检测数据对比分析得出:变真空预压法大幅度提高了真空预压的能效,对于加固深层淤土地基可以达到降低含水率、提高承载力,达到堤身稳定的目的,具有推广应用价值。
Because of poor foundation bearing capacity at Chongwan section of Huaihe-into-Yangtze River watercourse, the monitoring and test data between variable vacuum preloading method and traditional vacuum preloading method is compared in this paper. The result shows that variable vacuum preloading method greatly improves the efficiency of vacuum preloading, so as to reinforce the deep silt foundation through reducing moisture content and increasing the bearing capacity, finally achieving the purpose of the dike stability.
