摘要
随着交通建设的发展,隧道工程数量与规模不断增加,维持隧道开挖前后围岩稳定避免地质扰动对施工安全及工程推进至关重要。本文通过对比分析铁路隧道常见超前支护及初期支护形式,对工艺流程及其经济指标工机料等组成做了分析总结,为铁路隧道工程支护提供了参考,有助于在保证施工安全的前提下实现经济效益最大化。
With the development of transportation construction,the number and scale of tunnel projects are increasing,and it is very important to maintain the stability of the surrounding rock before and after tunnel excavation to avoid site disturbance.In this paper,through the comparative analysis of the common advanced support and initial support forms of railway tunnels,the process flow and its economic indicators,machinery and materials are analyzed and summarized,which provides a reference for the engineering support of railway tunnels,and helps to maximize the economic benefits under the premise of ensuring construction safety.
