电渗复合真空覆水预压法加固吹填土地基的应用研究
Application and Research of Combination of Electro-osmotic Method and Vacuum-overlying Water Preloading Method for Strengthening Dredger Fill
摘要
Abstract
Dredger fill has low permeability and high contant of bound water. Conventional vacuum preloading method can only exclude free water from the ground, and the efficiency is low to the such kind of soil. While electro-osmosis method has proved to be effective in the exclusion of bound water. So the combination of the electro-osmosis method and the vacuum-overlying water preloading method, was proposed to improve dredger fill ground. And the correlated in-suit tests were performed with the dredger fill ground treatment project in Wenzhou. The results showed that electro-osmosis method could effectively lower the groundwater level and contributed significantly to the growth of soil' s late strength. The combination method with electro-osmosis and vacuum preloading has achieved better effects than the vacuum preloading method alone, especially in the shortening of the construction period by increasing of the ground settlement rate.关键词
