Analysis of Freezing Method Construction Technology for Subway Connection Channel in Complex Geological Environment
ZUO Fei
Abstract：Due to the varying characteristics of different soil types in complex geological environments and the associated challenges of high groundwater levels,loose soil layers and strong permeability,this paper explores the application of the freezing method in the construction of subway connecting passages.Based on a specific subway connecting passage construction project,a comprehensive geological survey of the construction area was conducted.Soil samples were collected to measure moisture content and density parameters,and to calculate soil geology's physical characteristics indicators.Temperature and pressure relief hole measuring points were set up,freezing wall intersection circles were designed,and technical parameters for the freezing method construction were set to complete the construction of subway connecting passages in complex geological environments.The results show that the variation pattern of the frost heave force of the frozen wall in the proposed construction technology aligns with the relevant standards.The construction results demonstrate high stability and excellent performance,meeting construction safety standards for subway connecting passages.This technology has practical value and can be promoted and applied in real-life situations.
