【摘要】 在室内非足尺模型试验中,我们采用尺寸为60*40*3mm的塑料自封袋代替设计中的聚丙烯塑材料袋,试验选用的地基土是由内蒙古运来的成品细砂来模拟实际工程原状土。通过在相同数量砂袋情况下的埋深与堆放截面的改变、相同埋深条件下不同堆放截面和数量,对试验进行加载,得出摩擦型砂袋砂土加固法能够很大程度上提高地基承载力,有效的降低地基基础的沉降和不均匀沉降的结论。更多还原

【Abstract】 In this indoor simulation experiment,we choose the 60~*40~*3mm PE bags to take place to plastic woven bag in the design.In the experiment we use finished product of fine sand from Inner Mongolia to simulate the undisturbed soil in actual engineering,we can change the Buried depth and cross form in the same amount of soil bags,and differential cross form and amount of soil bags in the same Buried depth so on,guarantee in the same loading condition,we have concluded that frictional soil bags foundation reinforcement method has ability to improve bearing capacity of the ground.It also can decrease foundation’s settlement and uneven settlement.更多还原
