| 摘 要： | 模拟野外实测降温过程，对筋土复合体进行开敞条件下的冻融循环，然后对筋土复合体进行加载破坏试验，得到加载过程中墙体的竖向变形与墙面的水平位移结果．对试验结果进行有限元数值计算，其中土的本构模型采用Drucker-Prager（D-P）理想弹塑性模型，单元类型选用四节点平面等参单元，把筋材的作用等效成附加应力沿筋的方向加在...

| Abstract: | Aimed at modeling the in-situ measured temperature process,freeze-thaw cycling test on reinforcement-soil complex under open conditions was made.Then loading test was carried out,and the test results about vertical deformation of reinforcement-soil complex and lateral displacement of wall panel during loading process were recorded.The test data were processed by FEM numerical calculation.Drucker-Prager(D-P) ideal elastoplastic constitutive model was adopted to be the constitutive model.Four nodes plane isop... |
