Study of application of vacuum consolidation pressure to high moisture content soil/intermediate soil

本文讨论了真空固结技术在高含水率土/中间土中的应用。得到如下结果。1)利用弹性塑性本构方程SYS Cam粘土模型，可以较好地表达高含水率土/中间土的剪切特性，明确了其力学特性。2)对中间土进行了真空压力载荷试验，明确了真空压力对中间土的改良效果。3)进行了数值模拟，阐明了真空压力对土壤改良的作用机理。此外，还探讨了与路堤共同治理土壤的可能性。

This paper is discussed about the application of the vacuum consolidation to the high moisture content soil/intermediate soil. The followings are obtained. 1) Using the SYS Cam clay model ,which is the elasto plastic constitutive equation, the shear behaviors of the high moisture content soil/intermediate soil are appropriately expressible and the mechanical behavior is clarified. 2) The vacuum pressure load tests were performed for the intermediate soil, and it was clarified that that soil improvement by vacuum pressure was effective for the intermediate soil. 3) The numerical simulations were performed, and the mechanism of soil improvement for vacuum pressure is clarified. In addition, the possibility of soil improvement with embankment together was examined.
