A Composite Retaining Structure Combined with Reinforced Soil Structure and Anti-slide Pile

Abstract

The invention relates to a reinforced soil structure and slide-resistant pile combined composite retaining structure. In the composite retaining structure, a slide-resistant pile supports upper earth rock and rear soil, wherein the upper earth rock is of a reinforced soil structure. The reinforced soil structure enables upper soil to be integrated and solidified into one compact continuous flexible body to protect a slope and guarantee the stability of the soil. The slide-resistant pile is located on the bottom wall toe or the slope toe of the reinforced soil structure to prevent the upper reinforced soil structure and the rear soil from sliding down. The composite retaining structure can solve problems which can not be solved by some single retaining structures and forms, and is good in anti-seismic property and obvious in engineering effect.

[0002] With the development of the economy, the fields and areas of engineering construction are constantly expanding, and the natural environment and geological conditions of engineering construction are becoming more and more complex. In some projects with complex terrain and special engineering requirements, some high fill will appear. For projects, only a single support structure and measures can no longer meet the requirements of the project, and a combination of multiple support structures or measures must be used, especially when building projects in mountainous areas, this situation often occurs

[0003] When building projects in mountainous areas, we often encounter the problem of high fill or landslide treatment on slopes. Due to various external conditions or engineering safety considerations, it is often impossible to stack fill slopes naturally. Therefore, it is necessary to It carries out support reinforcement and prevents the filling body from sliding down the slope. The traditional and single filling support reinforcement method is difficult to solve such problems at the same time due to factors such as project cost, construction difficulty and site constraints.

[0004] Compared with other forms of traditional retaining structures, reinforced soil structures have the characteristics of simple structure, convenient construction, strong engineering adaptability, relatively low requirements for foundation bearing capacity, low cost, and good seismic performance. At the same time, geogrids have unique The mesh structure increases the embedding and occlusal effect of the soil particles, binds the filling soil more tightly, and forms a more stable overall flexible structure. The disadvantage is that the height of the single-stage wall should not exceed 10m, and improper construction will easily lead to deformation. It is too large and not suitable for application in flooded areas. It is a commonly used method for dealing with high fill projects at present.
