摘要
该文对无砂垫层真空联合水袋堆载预压法加固超软地基进行了介绍,笔者在浙江苍南进行了相应的现场试验,试验结果从室内试验和现场原位试验等方面进行分析,结果均表明该方法能够有效提高地基承载力,并能够增大硬壳层的厚度和土体的有效加固深度。同时对真空膜面覆水预压法进行了比较,分析了该方法存在的缺陷,特别是在产生"循环水"的情况下该方法的失效性。
In this paper,the method of no-sand cushion joint water bag vacuum preloading to reinforce super soft foundation are introduced,the author made field tests in zhejiang cangnan,the tests results from laboratory tests and field tests in situ were analyzed,and the results showed that this method can effectively improve the bearing capacity of foundation,and can increase the thickness of crust layer and the effective reinforcement depth.At the same time,vacuum membrane surface overlying water preloading method are compared,and the analysis of the defects of the method,especially in case of "cycle water",the failure of the method.
