涉水加筋土挡墙破坏机理的离心模型试验

摘要

Now the reinforced soil structure is applied widely. But the accidents of destabilizing and collapsing of the reinforced soil engineering especially reinforced soil retaining wall often happen, which has been paid attention to by academe and engineering field. Through the centrifuge model test, the structural characteristics and failure mechanism of the reinforced retaining wall are studied, and the regularities of soil pressure of the graded step-style grid reinforced retaining wall, the distribution for reinforcement tension and wall surface deformation are revealed. The deliverables has further developed the reinforced retaining wall research field, and will provide the reference for project practice.%目前加筋土结构的应用范围较广,但加筋土工程特别是加筋土挡墙失稳、破坏的事故时有发生,已引起学术界和工程界的高度关注.通过离心模型试验,研究加筋土挡墙的结构特性和破坏机理,揭示分级台阶式格栅加筋土挡墙的土压力、筋带拉力及墙面变形的分布规律,该成果进一步拓展了加筋土结构的研究领域,对工程实践具有一定的参考价值.
