针对温州瓯飞一期围垦水闸工程滩涂原淤泥土存在的问题,对真空预压加载方式进行改进,提出分级加载真空预压,并对原有的分级加载方法进行完善,通过对比四种不同真空荷载加载方式,找出最优的加载等级及具体的加载数值,指出采用二级加载对土体加固效果最佳。
In light of tidal silt soil problems of Wenzhou Oufei 1st period cofferdam sluice engineering,the paper improves vacuum preloading methods,and puts forward multi-stage vacuum preload,improves original multi-stage loading methods. Through comparing four kinds of vacuum preloading methods,it finds out optimal loading grades and specific loading numerical,and finally points out that:it has optimal reinforcement effects by applying secondary loading method.
