摘要
利用有限元计算软件,分析研究隧洞在不同围岩类型、不同外水压力作用及不同结构形式下的隧洞结构应力,为设计最终选择合适的断面形式提供技术支撑,可为类似工程提供借鉴。
Dashanshao tunnel in central Guizhou is the first hydraulic structure at the head of Guisong main canal.The tunnel has the characteristics of strong karst development,complex hydrogeological conditions,high water head outside the tunnel and large water inflow.In this paper,the finite element calculation software is used to analyze and study the tunnel structural stress under different surrounding rock types,without the action of external water pressure and different structural forms,so as to provide technical support for the final selection of appropriate section form in the design,in order to provide reference for similar projects.
