The aim of the proposed research is to develop methods for predicting stress distributions within geosynthetic reinforcements at working loads through an integrated program of experimental measurements and analytical modelling. Measurements of load transfer onto reinforcing inclusions will be achieved using the Automated Plan Strain Reinforcement (APSR) cell developed recently at MIT. Experiments will be performed using a dry sand with different classes of geosynthetic inclusions including: a) polymeric sheets ('geomembrane materials'), b)grids, c) woven fabrics, and d) non-woven fabrics. The results of the study will help to provide a rational basis for selection of reinforcing materials in design.

拟议研究的目的是开发方法， 土工合成材料加筋体内部应力分布预测 通过一个综合的实验项目， 测量和分析建模。负载测量 转移到加强夹杂物将实现使用 最近开发的自动平面应变加固（APSR）单元 在麻省理工。实验将使用干砂进行， 不同类别的土工合成材料内含物，包括： 聚合物片材（“土工膜材料”），B）网格，c）编织物 织物，和d）非织造织物。研究结果将 有助于为钢筋的选择提供合理的依据 设计中的材料。
