Analysis of freezing temperature field development and surrounding rock frost heave displacement in connecting passage
摘要
Abstract
To address the issues of temperature field evolution and frost heave deformation in artificial ground freezing(AGF)construction,this paper investigated a metro connecting passage project using numerical simulation.The spatiotemporal distribution characteristics of the frozen wall temperature field during the active freezing period,as well as the influence of frost heave on ground surface and tunnel structure deformation,were analyzed.The results indicated that the formation of the frozen wall exhibited non-uniformity,with slower development at corners and bottom regions.The complete closure of the frozen wall,occurring around the 25th day of freezing,marked a turning point in ground deformation rate.Frost heave induced significant uplift in both the ground surface and the surrounding strata of the connecting passage,with deformation curves following a ＂bell-shaped ＂distribution and demonstrating notable time-dependent accumulation effects.By the end of the 45-day active freezing period,the maximum surface uplift reached 6.2 mm,while the maximum uplift in the connecting passage strata attained 9.5 mm.关键词
