摘要

采用非线性有限元方法对土工织物加固软土路基的效果和机理进行了探讨。对比计算表明，土工织物对软土路基的加固有明显的效果，可使路堤的安全性提高20 %以上，使侧向位移减小15 %～25 %；土工织物对竖向沉降影响的大小则取决于路堤的宽度及土性参数；固结阶段的侧向位移会由于竖向沉降的大幅度发展而发生回缩，工程中需要采用较精密的仪器来探测这种回缩现象；仅铺设土工织物对路基体内孔隙水压力的发展影响不大，若要加快孔压的消散，可与塑料排水板联合使用；为了更好地发挥土工织物的加固效果，土工织物应尽量布置在高应力区域。分析后认为，传统的极限平衡分析方法很难合理地反映土工织物与土之间的变形协调关系，也较难正确地反映土工织物的受力状态及作用机理。

Abstract

The mechanism of road embankment reinforced with geotextile is studied with nonlinear finite element method. By comparative computing of the unreinforced road embankment with reinforced one

it is shown that the road embankment on soft soil foundation can be reinforced with geotextile effectively. The safety of embankment can be enhanced more than 20 ％ with geotextile

and the lateral displacement is reduced 15 %－25 %. Whether the vertical settlement could be reduced with geotextile or not

is dependents on the width of road and characteristic of foundation. With vertical settlement develops greatly

the lateral displacement at consolidation phase become less than that of construction phase. More exact instrument should be used to investigate the variation of lateral displacement at different construction phases. It is shown that there is no influence on dissipation of excess pore water pressure with geotxtile only. In order to reinforce the embankment effectively

it is advised that geotextile should be set on high-stress zone. Furthermore

the limitation of conventional limit equilibrium method used in investigating embankment reinforced with geotextile is analyzed.
