摘要
为了分析评价聚丙烯加筋土挡墙失稳的机理,选择科学合理的加固方案,对其进行有限元差值模拟分析,研究墙体产生的位移变形、土体塑性区分布的变化情况,并采用强度折减法对挡墙整体稳定性进行系统分析。结果表明:锚杆框架梁加固方案可以有效解决聚丙烯加筋土挡墙的失稳问题,可为解决同类问题提供借鉴。
In order to analyze and evaluate the mechanism of instability of polypropylene reinforced retaining wall,a scientific and reasonable reinforcement program was chosen,and the finite difference method was applied.By studying the displacement deformation of the wall and the changing of the plastic zone distribution of the soil,and using strength reduction method to conduct the systematic analysis of the overall stability of the retaining wall,it was found out that the reinforcement program that applied anchor frame beam effectively solved the instability problem of polypropylene reinforced retaining wall,which provides reference for solving similar problems.
