Abstract:For the influence of seepage on the freezing effect during the construction of the subway,the finite element software is used to simulate the actual arrangement of the freezing pipe with Nanjing Metro Line 3 as the engineering background to investigate the influence of seepage field on the temperature field.The results show that:when there is a head difference,the isothermal map surrounded by different temperatures will be offset with the direction of the head difference,and finally the isothermal line is no longer symmetrical distribution,and the larger the head difference,the higher the degree of asymmetry of the isothermal line,but the effect of the head difference on the temperature field will be weakened with the increase in the distance from the freezing pipe;the seepage direction of the freezing effect also has a certain impact,and therefore the actual project should control the seepage direction and the arrangement of the freezing pipe.Therefore,in the actual project,the direction of seepage should be controlled to be consistent with the direction of freezing pipe arrangement to strengthen the final freezing effect.
