以四川汶马高速C15合同段狮子坪索道桥为背景,对重载索道桥岩锚结构的设计和施工进行研究。岩锚的设计机理主要通过注浆材料与岩土、注浆材料与岩锚材料之间的黏结力来平衡索道桥的主索拉力,同时,通过岩锚设计对钢丝绳岩锚的关键施工工序进行介绍,以便为同类工程提供参考。
Taking the Shiziping cable bridge of C15 contract section of Sichuan Wenmao Expressway as the background, the design and construction of the rock - anchor structure of heavy cable railway bridge are studied. The design mechanism of rock anchor balances the main cable pulling force of the cable-stayed bridge mainly by the bonding force between grouting material and rock and soil, grouting material and rock anchor material. At the same time, the key construction procedure of wire rope rock anchor is carried out by rock anchor design Introduction, in order to provide reference for similar projects.
