| 摘 要： | “直排式真空预压地基处理方法”是在常规真空预压法基础上发展而来的新型地基处理方法，该方法取消了水平排水砂垫层，用密闭的真空管网将真空能量直接传递到排水板底部，真空利用效率大幅度提高。通过中交水运规划设计院有限公司在全国5个有代表性的软土地基加固试验区的试验结果对直排式真空预压软基加固效果及经济性进行分析，证明该方法针对不同类型的软土地基，能够有效进行加固并具有很好的经济性。

| Abstract: | Thedirect vacuum preloading method for ground treatment is developed on the base of the general vacuum preloading method.This method cancels horizontal drainage sand cushion and connects drainage board with sealed pipe network directly.The energy can be transmitted into the bottom of drainage board without decrement.The efficiency of vacuum energy is improved.This paper illustrates the soft ground reinforcement effect and the economic efficiency of direct vacuum preloading method for ground treatment with t... |
