针对真空预压排水固结法处理新近吹填淤泥地基工程,对采用不同长度竖向排水体的两个加固区域进行了现场试验研究,通过对比分析两个加固区的地表沉降、膜下真空度、孔隙水压力等现场监测结果及十字板试验、载荷板试验等检测结果以及室内土工试验所得的土体物理力学性质指标,得出结论:真空预压法处理新近吹填淤泥地基不仅可以达到一定的加固效果,而且通过延长竖向排水体的长度在一定程度上可以提高土体的固结效果。 In order to deal with the newly-filled silt foundation with vacuum pre-drainage and drainage consolidation method, two reinforced areas with vertical drainage bodies of different lengths were field-tested. By comparing the surface subsidence, sub-membrane vacuum , Pore water pressure on-site monitoring results and cross plate test, load plate test and other test results as well as physical and mechanical properties of soil test results obtained indoor, concluded: vacuum preloading method to deal with the newly blown mud base can not only achieve a certain Of the reinforcement effect, and by extending the length of the vertical drainage body to a certain extent, can improve soil consolidation effect.
