Abstract

An optimization method of shield tunnel starting end reinforcement solution, which specifically includes the following steps: acquiring shield tunnel engineering data and temperature variation curves of thermometer holes; constructing a numerical model with thermal convection and a hydro-thermal coupling numerical model respectively according to the shield tunnel engineering data, wherein a first temperature variation curve and a second temperature variation curve can be obtained after carrying out numerical simulations on the above two models; the influence of seepage on the development law of a temperature field can be obtained by comparing and analyzing the temperature variation curves of the thermometer holes with the first and the second temperature variation curves; and finally the existing freezing solution of the shield tunnel is optimized according to the influence of the seepage on the development law of the temperature field, to ensure safe use of the shield tunnel.
