本文描述了土壤-土工合成复合材料的单胞性能，其中模拟了土工合成材料加固土壤结构的主要构造和载荷条件。用三种类型的土工合成材料加固粉质粘土，每种土工合成材料具有不同的力学和水力学特性，并在平面应变压缩剪切之前各向同性或各向异性地固结。在排水和不排水条件下，这些因素对加筋土体的性能的影响进行了研究。结果表明，固结应力比和后续加载过程中的排水条件对加固效果有很大的影响。这些因素影响土壤和土工合成材料之间的相互作用，达到土工合成材料中的张应力被调动的程度，从而通过增加其强度和刚度来提供对土壤的增强限制。研究了土工合成材料的力学性能对加筋效果的影响。
This paper describes the performance of a unit cell of soil‐geosynthetic composite in which the predominant construction and loading conditions of a geosynthetic‐reinforced soil structure were simulated. A silty clay was reinforced with three types of geosynthetic, each having different mechanical and hydraulic properties, and consolidated isotropically or anisotropically before being sheared by plane strain compression. The effects these factors have on the performance of reinforced soil mass under drained and undrained conditions were investigated. It was found that the consolidation stress ratio and the drainage condition during subsequent loading have a profound influence on the reinforcement effect. These factors affect the interaction between soil and geosynthetic, to the extent to which the tensile stress in the geosynthetic is mobilized and thus provides enhanced confinement to the soil by increasing its strength and stiffness. The effects of mechanical properties of geosynthetic on the reinforcem...
