振动砂石桩法处理可液化软弱场地土

An Example of Liquefaction Ground Treated by Densification of Sand Pile

采用振动砂石桩法处理软弱地基形成复合地基,不但能提高地基的承截能力,同时能够消除地基液化对建筑物造成的不利影响.砂石桩法适用于挤密松散砂土、素填土和杂填土等地基,其对砂土的加固机理为挤密,对粘土的加固机理为置换,经该法处理后,地基的承载能力得到提高.

Densification of sand pile suits the ground of the lax sand, plain fill and miscellaneous fill. The reinforcing principle applied to the lax sand is densifieation. While the one on the other hand to the cohesive soil is displacement. The design and construction of densifieation by sand pile has special request. It can improve the bearing capacity and dissolves the disadvantageous influence on liquefaction ground when densifieation by sand pile is used to treat soft ground formed composite ground.
