| 摘 要： | 特大断面公路隧道由于跨度特大和扁平,加上施工期间诸多工序的相互影响、围岩的多次扰动等诸多因素,其受力条件极为复杂,在施工过程中,围岩极易发生失稳乃至坍塌.本文利用"公路隧道结构与围岩综合实验系统(CTSSSRH)",对特大断面隧道在不同施工方法下的施工动态过程进行了物理模拟,研究了特大断面隧道围岩位移、变形等发展规律,提出了特大断面隧道合理的施工方法.

| Abstract: | For the super-large section tunnel due to its super large span and flatness,together with the effect of various processes and excitation of surrounding rock during construction,the mechanical behavior of super-large section tunnel is quite complicated.Making use of the "CTSSSRH",the physical analogue for simulating the construction dynamic process of super-large section tunnel in different construction methods is experimented.The rule of surrounding rock displacement and strain development is studied and the reasonable construction method is put forward. |
