真空-堆载联合预压加固软土地基测试与研究

Test and study on reinforcement of soft clay foundation with vacuum-heaped load combined precompression

通过现场监测、试验及结果分析,对真空 堆载联合预压加固软土地基效果进行评价。试验表明,真空 堆载联合预压是较理想的加固软土地基方法,此法可大大提高软土地基的强度,加快地基固结速度,减小工后沉降,且地基稳定性较好。

Through site monitoring, test and results analysis, the consolidation effect of vacuum?heaped load combined precompression(VHLCP) was evaluated. The monitoring and test result indicated that VHLCP is a rational method to reinforce soft clay foundation. The method may greatly improve the strength of soft clay foundation, quicken the settling rate and decrease the settlement amount. After the consolidation being completed, the stability of foundation is improved.
