Abstract

The invention provides an anti-liquefaction treatment method for a liquefiable foundation, comprising the following steps: laying a gravel cushion, laying a gravel cushion with a preset thickness on the surface of the liquefiable foundation; constructing a drainage board, and determining the construction of gravel piles Position, the arrangement of crushed stone piles adopts regular triangles or squares, and the drainage board is inserted in the geometric center of the regular triangle or square arrangement between the crushed stone piles; the construction of crushed stone piles; continue to lay the crushed stone cushion, according to the design of the crushed stone cushion Thickness, lay the crushed stone cushion to the design thickness; lay the non-liquefied soil layer. The invention aims to solve the shortcomings of the existing anti-liquefaction treatment method for liquefiable foundations.

Description

technical field [0001] The invention belongs to the technical field of foundation treatment, in particular to a liquefaction-resistant treatment method for liquefiable foundations. Background technique [0002] For the liquefiable foundation treatment of deep sandy soil, the traditional method mainly adopts the compaction method and the drainage method. The compaction method mainly resists the cyclic shear stress under the earthquake force by increasing the compactness of the sandy soil. There are mainly dynamic compaction method and vibratory compaction method, but the treatment depth of dynamic compaction method is limited, generally the treatment effect is not good if it is larger than 10m, and the vibro compaction method is generally used for sandy soil larger than 10m, but the vibro compaction method is suitable for fine grain content greater than 20 % sandy soil treatment effect is not good; the drainage method mainly provides vertical drainage channels to dissipate th...
