振动挤密砂桩消除砂土液化和提高单桩承载力

Eliminating Liquefaction of Sandy Soil and Improving Bearing Capacity of Single Pile with Vibro-squeezing Sand Pile

该文结合工程实例 ,采用以灌砂率为参数的方法设计振动挤密砂桩处理液化地基 ,经检测 ,不仅消除砂土液化且提高了单桩承载力 ,为减少混凝土桩提供了必要条件 ,从而降低了成本 。

The paper takes the project as an example,and uses the method of taking the rate of filling sand as the parameter to design the vibro-squeezing sand pile for treating the foundation of liquefaction. Through the test, not only the liquefaction of sandy soil is eliminated, but also the bearing capacity of single pile is improved, and then essential conditions are provided for reducing concrete piles. The cost is decreased and the economic benefit is increased.
