Anti-liquefaction rigid-flexible composite retaining wall based on high polymer material and construction method of anti-liquefaction rigid-flexible composite retaining wall
The invention provides an anti-liquefaction rigid-flexible composite retaining wall based on a high polymer material and a construction method. The composite retaining wall comprises a rigid retaining wall body, a buffer layer, a side anti-liquefaction structure, an inverted filter layer and an ecological blanket. The rigid retaining wall body is located on one side of the buffer layer, the side anti-liquefaction structure and the inverted filter are sequentially arranged on the side, away from the rigid retaining wall body, of the buffer layer, and the ecological blanket is arranged on the side, away from the buffer layer, of the rigid retaining wall body. The construction method comprises the construction steps of construction preparation, construction of the water absorption piles, construction of the gravel cushion layer, construction of the rigid retaining wall body, construction of the buffer layer, construction of the side anti-liquefaction structure, construction of the inverted filter layer, construction of the ecological blanket and soil backfilling. The high polymer buffer layer is adopted as a flexible material, the main effect of buffering the lateral pressure of the soil body can be effectively achieved, backfill soil is allowed to generate certain displacement to release the shear strength of the soil body, and therefore the pressure acting on the retaining wall is reduced, and the retaining wall is prevented from being unstable and damaged.
本发明提供了一种基于高聚物材料的防液化刚柔复合挡土墙及施工方法，该复合挡土墙包括刚性挡土墙本体、缓冲层、侧面防液化结构、反滤层和生态毯；刚性挡土墙本体位于缓冲层的一侧，缓冲层远离刚性挡土墙本体的一侧依次设有侧面防液化结构和反滤层，生态毯设于刚性挡土墙本体远离缓冲层的一侧上。其施工步骤包括施工准备、吸水桩的施工、砂石垫层的施工、刚性挡土墙本体的施工、缓冲层的施工、侧面防液化结构的施工、反滤层的施工、生态毯的施工以及回填土。本发明中通过采用高聚物缓冲层作为柔性材料，可以有效发挥缓冲土体侧压力的主要作用，允许回填土产生一定的位移以释放土体的抗剪强度，从而减小作用在挡土墙上的压力，防止挡土墙失稳破坏。
