基于数值计算的某新型生态挡土墙力学特性分析

NUMERICAL ANALYSIS OF MECHANICAL PROPERTIES OF A NEW ECOLOGICAL RETAINING WALL

  • 摘要: 城市化发展日益表现出对城市建设与生态环境协调关系的重视。作为挡土墙的重要类型之一,生态挡土墙逐渐成为城市挡土墙建设的重要部分。本文提出并设计出了一种新型装配式生态挡土墙,经工程实践,该挡土墙可有效建立两侧水力联系,体现出较好的生态价值。为论证该生态挡土墙的力学稳定性,采用ANSYS数值模拟的方法,对新型生态挡土墙进行了变形与应力分布规律的研究,计算结果与相关规范要求对比表明该生态挡土墙在稳定性方面均满足要求。最后运用层次分析法对挡土墙土压力的主要影响因素进行了敏感性分析,结果表明挡土墙结构的选型以及结构材料这两个指标的权重最高。研究成果可为实际工程安全控制提供有效依据。

     

    Abstract: With the development of urbanization, more and more attention has been paid to the coordination between urban construction and ecological environment. As one of the important types of retaining walls, the research and development of ecological retaining walls have gradually become a crucial part of retaining wall design. A new type of prefabricated ecological retaining wall was proposed in this paper. The engineering practice shows that the retaining wall can effectively establish hydraulic connection on both sides of the wall, which shows a good ecological value. Moreover, the ANSYS numerical simulation method was used to investigate the deformation and stress distribution of the new ecological retaining wall to demonstrate the stability of the ecological retaining wall. Finally, the sensitivity analysis of the main influencing factors of the earth pressure of the retaining wall is carried out by using the AHP (analytic hierarchy process) method, and the results show that the two indexes, i.e., the retaining wall structure and the structural material, are the most important. The research results of this paper provide an effective basis for the actual engineering safety control.
