挤密砂砾桩处理盐渍土软弱地基效果分析

Effect Analysis of Salinized-soil Soft Foundation with Compacted Sand-pile

结合新疆奎屯至赛里木湖公路工程施工中的盐渍土软弱地基处理实例,研究了盐渍土地基的处理方法及挤密砂砾桩加固软弱地基的机理,对振动挤密砂砾桩处理盐渍土软弱地基效果进行了重点分析。工程完工后的地基承载力试验及沉降观测结果表明,加固效果十分理想。

In combination with the soft-soil foundation treatment of the highway from Kuitun-Sailimu Lake in Xinjiang,the treating method of salinized-soil foundation and the mechanism of compacted sand-pile enhanced soft foundation are studied,the effect of the salinized soft foundation treated with vibrated and compacted sand-pile is amphatically analyzed,after the project is completed a load bearing test and a settlement observation are conducted,the result shows that result of enhancement is ideal.
