    动荷载及降雨影响下加筋土结构稳定性研究现状综述

    A RESEARCH REVIEW OF THE STABILITY OF REINFORCED SOIL STRUCTURES WITH CONSIDERATION OF DYNAMIC LOAD AND RAINFALL

    • 摘要: 作为一种新型土工结构,加筋土结构变形及稳定性特征会受到各种内、外复杂因素的影响。内部因素主要包括筋材长度、加筋间距、刚度、面板形式、填料密实度等加筋土结构自身因素,目前对于此方面的研究已有很多人做了大量研究,也积累了很多经验。而对外部因素影响的研究相对较少,影响加筋土结构稳定性主要包括地震、降雨及交通荷载等外部环境因素。其中,对于加筋土结构动力特性的研究已有一定的研究基础,但是很少有学者关注降雨因素的影响,尤其是对于动力荷载和降雨共同作用下加筋土结构稳定性的研究更少。本文在大量文献分析的基础上,从动力荷载、降雨以及动力荷载和降雨共同作用3个方面论述已有加筋土结构稳定性的研究现状,分析了目前加筋土结构稳定性研究中的一些不足。笔者认为考虑动力荷载和降雨共同作用下加筋土结构稳定性研究具有十分重要的实际意义,且复杂环境条件下加筋土结构稳定性研究将成为今后研究的重点和发展方向。

       

      Abstract: As a new type of geotechnical structure, the deformation and stability characteristics of reinforced soil structures will be affected by various internal and external factors. The internal factors mainly include the length and stiffness of the reinforcement, spacing, panel type, the dense of fillings, et al. At present, a lot of related researches have been done and much experience has been accumulated. However, there are relatively a few studies on the influence of external factors which mainly include earthquake, rainfall, traffic load and so on. There are some researches on the dynamic behaviors of reinforced soil structures under earthquake loads and traffic loads has been done, but little attention was paid on the influence of rainfall, especially under the combined effect of dynamic loads and rainfall. Based on the analysis of a large number of literatures, this paper discusses the research statusregarding to three influences of reinforced soil stability:dynamic load, rainfall ad their combined effect. What's more, some deficiencies of these researches will be pointed out. It is believed that the study on the stability of reinforced soil under the combined effect of dynamic load and rainfall is significant in practices, and that under complex environmental conditions will become the focus and development direction in the future.
