在高陡峡谷区,路肩桩板墙作为一种普遍使用的支挡结构,具有施工方便、造价较低、外形美观的特点。但由于板挡墙结构的复杂性以及高陡边坡的支档难度,该结构的受力特性尚不完全明确。以相似比1∶25建立了路基边坡模型,通过室内模型试验,模拟并研究了不同工况下桩板墙的受力状态和位移大小以及土体压力随试验步骤的变化,根据试验结果对高陡边坡的变形与破坏机理进行了分析。
In the high steep gorge area, the shoulder pile wall as a commonly used support structure, with the construction convenience, low cost, beautiful appearance characteristics. However, due to the complexity of the structure of the retaining wall and the difficulty of supporting the steep slope, the mechanical properties of the structure are not yet fully understood. The subgrade slope model was established with similarity ratio 1:25. Through the indoor model test, the stress state and displacement of pile wall under different working conditions and the variation of soil pressure with the test procedure were simulated and studied. According to the experimental results The deformation and failure mechanism of high steep slope are analyzed.
