摘要:
受作业空间小和高地应力大变形的共同影响,单线铁路大变形隧道的施工进度大幅降低。现行铁路隧道施工定额无法充分反映单线铁路隧道由于大变形引起的进度滞后和成本增加问题。本文以某铁路隧道为依托,通过对大变形区段循环进尺及其作业时间的分析,以及现场施工进度的统计,得出了单线铁路隧道不同大变形等级的月进度指标,分析了大变形区段进度减少的主要原因。研究结论对单线铁路大变形隧道的投资和进度控制有一定借鉴意义。
Abstract:
The construction progress of single-track railway tunnels with large deformation is significantly reduced due to the combined effects of limited working space and high ground stress-induced large deformations. The current construction quotas for railway tunnels cannot fully reflect the progress delays and cost increases caused by large deformations in single-track railway tunnels. Based on a specific railway tunnel project, this paper analyzed the drilling cycle advance and operating time in sections with large deformations, along with statistics on the actual construction progress. It derived monthly progress indicators for different levels of large deformations in single-track railway tunnels and analyzed the primary reasons for the reduced progress in sections with large deformations. The research findings provide certain reference significance for the investment and progress control in single-track railway tunnels with large deformations.
