摘要
针对我国公路隧道修建日益增多及岩溶分布广泛的现状 ,利用“公路隧道结构与围岩综合实验系统 (CTSSSRH)”和有限元分析程序对岩溶区公路隧道围岩稳定性进行了一系列的大型相似模型试验和数值模拟研究 ,探讨了溶洞大小对围岩稳定性的影响 。
Considering the current situation that more and more highway tunnels are constructed and the Karst distribution is in broad range in China, a large conformable model test and numerical simulation on surrounding rock stability of highway tunnel were carried out. The influence of Karst cave scale on stability of the surrounding rock and some rules about the relationship between stability of surrounding rock and Karst are obtained.
