摘要:

以江苏省吴江市高等级道路地基处理工程为例,探讨了高真空击密法和低位高真空分层预压击密法的适用性,介绍 了2种方法的原理,并与现场静力触探试验进行对比分析,研究了2种方法对软土的加固规律。结果表明:2种方法处理后的 软土地基强度得到了不同程度的提高,采用低位高真空分层预压击密法处理后的地基加固效果更好。

Abstract:

Taking the project-foundation treatment with advanced road in Wujiang district, Jiangsu Province as an example, authors discussed the two updated skills of soft foundation treatment, i.e. high vacuum densification method(HVDM)as well as shallow high vacuum layered preloading and densification method(SHVLPDM). Based on theories of the two methods, authors analyzed the data of static cone penetration test measured on site correlatively to explain the advantage of SHVLPDM while dealing with soft foundation. The results indicate that the bearing capacities of soil foundation after treating are improved in different degrees by two methods, and the treatment effect by SHVLPDM would be better.
