真空预压浅层处理法在天津沿海软基处理中的应用研究

Application of vacuum preloading method in Tianjin coastal soft foundation consolidation

通过对比分析真空预压法中的浅层处理方式和常规深层处理方式的特点,分析了浅层处理方式应用于天津沿海软基加固工程中的优势之处,并结合工程实例对2种方式处理天津邮轮码头地基的效果进行了比较研究。研究结果表明:软基加固后土体的物理力学性质方面,浅层处理法要略优于常规处理法。因此,真空预压法浅层处理方式在天津沿海工程淤泥质地基处理中具有可行性。

The comparative analysis of shallow layer approach and conventional deep layer approach of vacuum preloading method were conducted,and the advantages for using shallow layer approach into Tianjin coastal soft foundation were analyzed. Two approaches were applied into soft foundation consolidation of Tianjin Cruise Terminal Project. The results show that：the shallow layer approach is better than conventional deep layer approach for soft foundation consolidation in physical mechanics performance. Therefore ,the application of the shallow layer approach into Tianjin coastal soft foundation consolidation is feasible.
