摘要
结合工程实例,为解决工程中处理深度较大、工后沉降要求高且工期要求紧等问题,采用真空联合堆载预压的方法进行软基处理,分别从作用机理、方案设计和加固效果等方面进行应用研究。研究结果表明:真空联合堆载预压法在软基处理中加固效果好,并且其固结度可达92.2%,地基承载力得到显著提高。
Combined with the engineering project, with the aims of solving problems such as large processing depth, high requirements on post - construction settlement and construction period and so on, the soft soil has been improved with the application of vacuum- combined surcharge preloading. The study has been carried out separately in the following matters, namely mechanism, scheme design and reinforcement effect. The result shows that the application of vacuum - combined surcharge preloading has a favorable impact on the reinforcement effect of soft foundation treatment, and the degree of consolidation can reach 92. 2%. The bearing capability of the foundation soil has been improved greatly.
