| 中文摘要: |
| 土工袋利用袋子张力作用使得袋内土体的强度得到提高，作为一种新型的土工合成材料被逐渐渗入到建筑物基础、道路（铁路）路基等工程中.本文从模拟软件介绍、土体本构、袋子单元、接触分析和算例计算5个方面，概述了基于Abaqus有限元软件的土工袋数值模拟.通过土工袋无侧限压缩试验模拟以及土工袋水平剪切试验模拟验证所选本构、单元、接触等的可行性. |
| 英文摘要: |
| As a new type of geosynthetics，geotextile is gradually infiltrated into building foundation，road（railway）subgrade and other projects.On the basis of previous studies，this paper summarizes the numerical simulation of geobags based on Abaqus commercial finite element software from five aspects：the introduction of simulation software，soil constitutive model， bag element， contact analysis and example calculation.The feasibility of the selected constitutive model，element and contact is verified by unconfined compression test and horizontal shear test. |
