Study On The Processing Of The Salinified Soft Base By The Sand Column Of Vibration Diving Casting And Crowd Dense

Salinize soft base have the characteristics not only of salinized soil, but also of weak earth. The characteristics conclude high moisture content, low shear strength, big compressibility coefficient, low ground supporting capacity, dissolves falls, salty swell and corrosivity. So we must adopt the science project measure to carry on processing, to improve the character of foundation soil body and enhance the ground supporting capacity and the stability.Unifying the foundation treatment experiment project of jia an Superhighway and the experimental study to salinified soft base processing, through inside and outside Experiment, this article analyzes the influence factor and the change rule of salinified soft soil ground special nature and physics mechanical properties, In this foundation, drawing lessons from the ripe processing measure of soft soil foundation, according to the condition of the construction site, adopting vibration immersed tube crowd dense grit compound method of the foundation treatment to the soft base of salinization., through loading test, cooperating with the test and observe live in site while being other. After that, Ms article analyzes and research the foundation bears the weight of strength, subsiding amount and tempo of subsiding. The project practice indicates that this technology is feasible, the economy is reasonable, and satisfies the operation requirements, so this technology has the very high promoted value.
