摘要/Abstract

摘要： 根据苏州轨道交通2号线火车站东风井盾构进出洞2#洞门水平冻结加固工程要求,利用有限元软件进行数值模拟,对掌子面对流系数、土体导热系数、容积热容量、相变潜热、水泥参量等因素进行敏感性分析。结果表明:掌子面对流系数、土体容积热容量与冻结效果呈线性递减关系; 土体导热系数与冻结效果呈线性递增关系; 相变潜热基本不影响冻结效果; 在水泥土中进行冻结时存在一冻结最佳水泥参量,粉质黏土中为12%、粉砂土中为16%。

Abstract: Relying on the horizontal soil freezing construction for 2﹟tunnel portal of shield entry projects in railway station of the second line of Suzhou Metro, numerical model of freezing temperature field is built for horizontal freezing shield portal by software. Effects of convection coefficient, thermal conductivity,volumetric heat capacity,latent heat of phase change,cement parameter on development of freezing effect were studied. The study demonstrates that the convection coefficient and volumetric heat capacity each with the freezing effect show two linear decreasing functions. The thermal conductivity with the freezing effect shows a linear decreasing function. But the latent heat of phase change has no effect on freezing effect. When the cement parameter is 20% in silty clay and 16% in silty soil, the freezing effect is the best.
