摘要
以岩溶区大断面隧道开挖为研究对象,采用数值模拟方法,针对不同岩溶位置和大断面的工程特征,对相关耦合力学特性、关键施工工序和施工工法等施工关键技术,开展了深入的研究。
Taking a large section tunnel in karst area as the research object, the deep research on key technologies of construction like relevant mechanics characteristic of coupling, key construction procedure and construction method and etc. is made by adopting the numerical simulation method and aiming at the engineering features of karst and large section.
