Numerical Simulation of Frozen Construction of the Cross-River Tunnel's Connected Aisle

Abstract:

Double-line cross-river shield tunnels should be set up evacuation routes for disaster prevention, rescue and ventilation at each distance according to the standard requirement, the evacuation passageway generally chooses transverse evacuation passageway, but in the case of complex geological and hydrological conditions, the risk of the construction of horizontal evacuation passages is very big. This paper takes a cross-river tunnel as an example, to set analysis for the risk of setting a horizontal evacuation passages. Used the ANSYS of a 3-d finite element analysis software, selected the number two horizontal channel as the prototype, according to the size and design of shield tunnel line longitudinal cross section of geological structure, establish the finite element calculation model for the interaction of the tunnel, the channel and the surrounding soil, to simulate the process of the excavation of the channel, and the paper studies the risk in the construction process of the channel.
