| 摘 要： | 为了解隧道施工中各横断面在纵向上的变形相关性,以湖北谷竹高速宴家隧道为工程背景,对各断面拱顶下沉值和水平收敛值进行全过程监控量测,并利用数值模拟软件ABAQUS进行数值分析.通过对实际施工过程中监控量测和数值模拟结果的分析,总结出在纵向上各断面拱顶下沉和水平收敛与围岩性质的关系,指出拱顶下沉为控制施工的关键因素,是反映围岩稳定性和力学状态最直观的数据.

| Abstract: | In order to analyze the correlation of vertical deformation of the cross correlation during tunnel construction,the vault settlement and horizontal convergence of all sections are measured based on Yanjia Tunnel of Gucheng-Zhuxi Expressway.Furthermore the software ABAQUS is used to analyze the vault settlement and horizontal convergence.Through analysis on the monitored and simulated data,the relation of surrounding rock features with the vault settlement and horizontal convergence are summed up.It is pointed out that the vault settlement are one of main factors for controlling construction,and it is the direct data that reflecting stability of surrounding rock and mechanical state. |
