高真空击密法加固吹填软土地基试验研究

高真空击密法是一种快速加固软土地基的新技术，它是通过数遍的高真空压差排水，并结合数遍合适的变能量击密，达到降低土层的含水率、提高密实度和承载力、减少地基工后沉降和差异沉降量的目的。为验证该工法在本工程吹填土质中的适用性，在汽车堆场区进行了典型试验。试验检测结果表明，地基容许承载力、地基沉降、地基回弹模量等各项指标均达到了设计要求，处理效果明显。对大连大窑湾港区类似工程具有参考价值。

Experimental research on high-vacuum densification method in reinforcing hydraulic fill soft soil foundation

High-vacuum densification method is a new technology for rapid reinforcement of soft soil foundation,by which we are capable of reducing the water content of the soil,improving the compactness and bearing capacity and reducing the amount of settlement and differential settlement of the foundation after construction through several times of high-vacuum differential pressure drainage and several times of appropriate variable energy densification.To validate the applicability of this method in the project,we carry out typical tests in the car yard area.The test results reveal that the allowable bearing capacity,foundation settlement,foundation modulus of resilience and other indicators all meet the design requirements,and the treatment effect is obvious.It may serve as reference for similar projects at Dayaowan port area of Dalian
