Supporting structure for tunnel anchor under soft rock stratum condition and construction method of supporting structure
The supporting structure for the tunnel anchor under the soft rock stratum condition is characterized in that the supporting structure comprises two rows of anti-slide pile assemblies and a bearing platform (2) arranged above the anti-slide pile assemblies; each anti-slide pile assembly comprises two anti-slide piles (1), and the two anti-slide piles (1) in one anti-slide pile assembly are arranged on the two sides of the tunnel anchor (a) correspondingly. The slide-resistant pile assembly and the bearing platform (2) are both arranged in a mountain and used for supporting loads of the mountain. The invention further provides a construction method of the supporting structure. According to the supporting structure, a system of the anti-slide pile and the bearing platform is utilized, the load and force transmission mode of the mountain body above the tunnel anchor cavern is clear and definite, the reinforcing effect is good, and the stability problem of excavation of the tunnel anchor at the slope toe of the high and steep slope under the complex geological condition is solved.
本申请公开了一种用于软岩地层条件下隧道锚的支护结构，其特征在于，包括两排抗滑桩组件，以及设于抗滑桩组件上方的承台(2)；每个抗滑桩组件均包括两个抗滑桩(1)，且一个抗滑桩组件内的两个抗滑桩(1)分别设于隧道锚(a)的两侧；所述抗滑桩组件和承台(2)均设于山体内，用于支撑山体载荷。本申请还提供上述支护结构施工方法。本申请提供的支护结构，利用“抗滑桩+承台”的体系，则隧道锚洞室上方山体载荷，传力模式清晰明确，加固效果良好、解决了在复杂地质条件下高陡边坡坡脚开挖隧道锚的稳定性问题。
