【摘要】 结合真空预压治理深圳河二期工程现场试验,分析了真空预压对周围环境的影响及不同防护措施的防护效果。采用水泥土搅拌桩可减少土体向加固区内的侧向位移,降低真空预压对周围环境的影响,其中格栅型水泥搅拌桩墙的防护效果明显好于采用两排紧密布设水泥搅拌桩墙的防护效果。更多还原

【Abstract】 Combining site test results of Phase Ⅱ Engineering of Shenzhen River, this paper analyzes the effects of vacuum preloading to surrounding environment and preventive measures. The cement- soil mixed piles can reduce the lateral displacement of soil towards the consolidating area and the effects of vacuum preloading to the surrounding environment. The preventive effect of the grid- shape pile wall is obviously better than the closly arranged two- rowpile wall.更多还原
