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。
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 superlarge 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.
