摘要
通过对国内14个轨道交通建设城市第三方监测资料的统计分析,研究工程变形的规律,明确不同监测项目的变形值分布形态,分析工程支护结构、周边地表和环境对象的变形特点,认为工程变形受设计因素、地质条件、环境条件和施工管理与质量等多种因素的影响,给出变形控制指标确定的基本原则。研究成果可对城市轨道交通工程变形控制指标的确定提供借鉴。
Based on the statistical analysis of the monitoring data of the third party of 14 cities, the engineering deformation law was studied. The deformation distributions of monitoring items were pointed out. The deformation characteristics of supporting structure, surrounding ground and environment objects were analyzed. The engineering deformation is influeneed by many factors, such as design factors, geological and environmental conditions, and construction management and quality. The basic principle to determine deformation control index was given. The research achievement may give important guidance to determine urban rail transit deformation control index.
