摘要 为研究隧道台阶法施工台阶长度对隧道变形的影响,以甘肃省某隧道台阶法施工的上台阶长度和循环开挖进尺为参数,采用三维有限元计算模型,进行围岩及支护结构稳定性分析。结果表明:上台阶长度对塑性区范围、围岩应力、拱顶下沉及周边收敛有显著影响;随着循环进尺的增加,最大地表沉降逐渐增大,在距离隧道中心线两侧25 m以外,地表沉降增长速率迅速减小并趋于平稳;Ⅳ级围岩地段,上台阶长度取开挖跨度的1~1.5倍,约为15 m;循环开挖进尺为1.5 m。隧道施工过程中,围岩位移、地表沉降等监测结果均满足施工安全要求,验证了本模型数据分析的安全性和准确性,该研究结果可以为采用台阶法施工的隧道提供一定的借鉴。

Abstract: In order to study the effect of upper step length on tunnel deformation in tunnel step construction, the stability of surrounding rock and supporting structure was analyzed by using three dimensional finite element model, taking the step length and circular excavation length of a tunnel in Gansu province as parameters. The results showed that the length of the upper step had a significant impact on the plastic area range, surrounding rock stress, arch subsidence and surrounding convergence; the maximum surface settlement gradually increases. Besides 25 m from the tunnel center line, the surface settlement growth rate slows down and stabilizes; the length of the upper step is 1~1.5 times, about 15 m, and the circulating excavation meter was 1.5 m. During the tunnel construction, the monitoring results of surrounding rock displacement and surface settlement met the construction safety requirements, and verify the safety and accuracy of the analysis of the model data analysis. The research results can provide some reference for the tunnel constructed by step method.
