摘要
结合郑州地铁丰庆路~文化路站区间实际情况及施工重难点,分析冷冻法地层加固施工技术在地铁区间联络通道工程中的施工要点及应用效果。结果表明:含水量较大的地层经过冷冻法加固后,具有良好的匀质性、自立性,不存在侧限抗压强度,渗透系数达标等优势,可为地铁区间联络通道工程施工提供良好的环境,值得大范围推广应用。
In order to explore the application effect of the freezing method in the construction of the connecting passage of the subway section,combining with the actual situation of the section from Fengqing Road station to Wenhua Road station and the analysis of the key and difficult points in the construction,this paper discusses the key points of the application of the freezing method in the construction of the connecting passage of the subway section.The analysis shows that the stratum with large water content,after being reinforced by freezing method,has the advantages of good homogeneity,self-reliance,no lateral compressive strength,and the permeability coefficient meets the standard,which can provide a good environment for the construction of the subway section connecting passage project,which is worthy of wide promotion and application.
