Water Conveyance Tunnel

The construction process of water conveyance tunnel is complex and stochastic under the karst geological condition. Aiming at analyzing the construction process under this special condition, a simulation modeling method of water conveyance tunnel construction is presented. Through demonstrating the simulation analysis and predicting the schedules in a real case study of a water conveyance tunnel, this method is proved advanced and intuitive for formulating and analyzing the construction schedules under the karst geological condition.

A deep-buried highway tunnel is constructed with complex geological condition which existing an alternation of soft and hard rock and having feature of high ground stress, and extrusion, fall-block and twisted phenomena of supporting structure appear in many places during construction which pose a serious threat to the safety of tunnel construction. In combination with the construction process of Shimenya tunnel, by using the finite difference software FLAC3D, the surrounding rock stability is simulated, and the numerical calculation results of advanced pilot excavation method with different structural inclinations. The conclusion can be used for reference for the design and research of similar tunnels.
