摘要
针对路基水毁冲失段公路交通应急通行迫切需求,研发了应急锚拉框架结构新技术。在介绍应急锚拉框架结构组成的基础上,采用超静定结构力学和极限平衡理论,建立了应急锚拉框架结构框架横梁的内力、锚固钢绳拉力、斜支撑结构内力的计算方法。凉山金阳公路修复工程的应用表明:所建成的路基水毁冲失段应急锚拉框架结构安全可靠、实用性较强,可满足交通应急通行的快速恢复交通需求。
On the basis of introducing structural composition of emergency anchor frame structure, the statically indeterminate structure mechanics and the ultimate balance theory are adopted to establish the calculation method for endogenous force of frame beam,tension of anchor wire cable,structure endogenous force of inclined beam to the emergency anchor frame structure. The application in highway restoration project in Jinyang, Liangshan Yi Autonomous Prefecture shows that the emergency anchor frame structure in waterlogging washout section of subgrade is safe, reliable, and well practical, which can meet the rapid traffic restoration demand in emergency.
