| Abstract: | Based on two-dimensional finite element model,a numerical simulation method was introduced for analyzing and simulating temperature field during freezing shaft sinking.In this method the deflection of the freezing bores and temperature value of temperature hole were taken into consideration.The simulation results have a very good coherence with the temperature value of temperature hole,so the calculated of freezing temperature field distribution has high precision. |
