文章通过某高速公路粘土填方路基强夯加固的实例,在分析试验区强夯施工现场地面沉降及超静孔隙水压力监测资料基础上,结合强夯处理后多种手段检验地基加固的效果。可以认为采用强夯法加固路基,不仅可提高地基承载力,而且可以加速填方路基的固结沉降;同时通过提高路基加固后的均匀性来减小工后的不均匀沉降。运用这一强夯新工艺加固软粘土地基可以取得满意的效果。
Based on the analysis of the ground subsidence and excess pore water pressure monitoring data of the dynamic compaction site in the experimental area, the article examines the effect of the foundation reinforcement by means of various methods after the dynamic compaction treatment. It can be considered that the use of dynamic consolidation method to reinforce subgrade can not only improve the bearing capacity of foundation, but also accelerate the consolidation and settlement of filled embankment; at the same time, it can reduce the uneven subsidence of post-construction by improving the uniformity after subgrade reinforcement. The use of this dynamic compaction of new technology to strengthen soft clay foundations can achieve satisfactory results.
