摘要: 通过非线性有限单元法分析了堤坝下软基土工织物的加筋效果,土与土工织物的界面强度对加筋效果的影响,多层土工织物的加筋效果等问题,得出了最优加筋层数、加筋垫层应力扩散效果等一系列对工程设计有用的结论Abstract: In this paper, a non|linear finite element analysis for soft cohesive ground under embankment reinforced by geotextile has been made to obtain the influence of interface strength between soil and geotextile on reinforcing effect, reinforcement effects for single and multilayer geotextile, etc. Some profitable conclusions for engineering project, such as optimum reinforcement layer number and stress dispersion effect of reinforcement cushion, have been obtained.
