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

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.
