各种地基处理方法,要详细的（Various ground treatment methods, should be detailed） Various ground treatment methods should be detailed Reward points: 0 - solve the time: 2010-10-15 15:26 Questioner: brother Legend - ground treatment methods commonly used one best answer The common foundation treatment methods are: replacement cushion method, dynamic compaction method, sand pile method, vibroflotation method, cement mixing method, high-pressure jet grouting method, preloading method, compaction soil cement pile, cement fly ash gravel pile method, lime pile and lime soil compaction pile method and soil compaction pile method, thrusted expanded pile method, single fluid method and alkali method of silicide. 1. The change filling cushion method is suitable for shallow weak ground and uneven foundation treatment. Its main function is to increase the bearing capacity of the foundation, reduce the settlement, accelerate the drainage consolidation of the weak soil layer, prevent the frost heave and eliminate the swelling and shrinkage of the expansive soil. 2, the dynamic consolidation method is applicable to the treatment of gravelly soil, sand, low saturation silt and clayey soil, collapsible loess, miscellaneous fill and plain fill soil and other foundations. The dynamic consolidation replacement method is applicable to the engineering of the high saturation silty soil and the soft plastic clay soil. The design of this method must be confirmed by field test before the design. Dynamic compaction and dynamic consolidation replacement method are mainly used to improve soil strength, reduce compressibility, improve soil resistance to vibration liquefaction capacity and eliminate soil collapsibility. For saturated cohesive soil, it should be combined with surcharge preloading method and vertical drainage method. 3, sand gravel pile method is applicable to compaction loose sand, silt soil, cohesive soil, plain filling and miscellaneous fill soil foundation, so as to improve the bearing capac
