Semicircular vertical pre-stressed anchor cable slide-resistant pile and stress calculation method
The invention discloses a semicircular vertical pre-stressed anchor cable anti-slide pile and a stress calculation method. The semicircular vertical pre-stressed anchor cable anti-slide pile comprises an anti-slide pile body and a pre-stressed anchor cable. The anti-slide pile is vertically arranged on the landslide, the section of the anti-slide pile is semicircular, and the side with the cambered surface faces the slope surface; the pre-stressed anchor cables are vertically arranged in the slide-resistant piles, the two ends of each pre-stressed anchor cable are fixed in the slide-resistant piles, and the pre-stressed anchor cables are located on the sides, close to the arc faces, in the slide-resistant piles. By means of the semicircular vertical pre-stressed anchor cable anti-slide pile and the stress calculation method, the defects of a traditional cantilever anti-slide pile are overcome, the protection effect of concrete is utilized, the vertical reverse bending moment formed by pre-stress is utilized, the anchor cables are arranged in the anti-slide pile, the failure caused by the soaking effect of underground water can be avoided, and the service life of the anti-slide pile is prolonged. And disturbance damage of an earthquake to the steel strand is effectively reduced. And compared with a rectangular anti-slide pile, the semicircular anti-slide pile is more beneficial to counteracting landslide thrust in different directions, and compared with a circular anti-slide pile, the semicircular anti-slide pile reduces about 1/2 of the material consumption and saves the construction cost.
本发明公开了一种半圆形竖向预应力锚索抗滑桩及受力计算方法，包括抗滑桩和预应力锚索；抗滑桩竖直设置在滑坡上，且截面呈半圆形状，具有弧面的一侧朝向坡面设置；预应力锚索竖直设置在抗滑桩内，且两端均固定在抗滑桩内，预应力锚索位于抗滑桩内靠近弧面的一侧。使用上述一种半圆形竖向预应力锚索抗滑桩及受力计算方法，弥补了传统悬臂抗滑桩的不足，既利用了混凝土的防护作用，又利用了预应力形成的竖向反向弯矩，并且锚索设置于抗滑桩内，可避免因地下水浸泡作用而导致失效，有效降低地震对钢绞线的扰动破坏。半圆形相比于矩形抗滑桩，更有利于抵消不同方向的滑坡推力，相比于圆形抗滑桩减少了材料的约1/2用量，节省了工程造价成本。
