摘要
为了避免突水事件的发生,并保证隧道施工安全,采用有限元法,对不同溶洞条件下公路隧道的施工过程进行了数值模拟分析,结果表明:在隧道施工中,溶洞洞壁的厚度和溶洞内水压力的大小是引起岩溶突水的关键因素。
In order to avoid the appearance of water inflow and guarantee the safety during the tunnels, mechanical behaviors of the highway tunnel constructed in the Karst areas are analyzed construction of with finite ele- ment method（FEM） under different hydraulic pressures and thicknesses between cavern and tunnel. The research results show that hydraulic pressure and wall thickness are two key factors to the water inflow during highway tunnels construction in Karst areas.
