摘要
通过非线性有限元法研究了软基上土工织物加筋路堤实际工况下软基超静孔压消散、软土地基竖向变形和塑性区分布规律,同时分析了筋材应变及其水平向分布、未加筋与加筋路堤工后沉降历时曲线及其水平向分布规律,揭示了筋材协调土体变形,减小不均匀沉降,同时减小路堤工后沉降的作用机理。
The mechanical behaviors of the reinforced embankment are studied using the nonlinear finite element method, which includes the dissipation of pore pressure, vertical displacement, distribution of yielding zone in the soft clay, and the strain of the geotextiles in horizontal direction, Based on the results of numerical analysis, some comparisons of the post - construction settlements between reinforced and non - reinforced embankment are made to show the mechanism of reinforcement. That is, the differential settlement of the embankment can be effectively decreased by application of the geotextile reinforcement,
