摘要
通过对我国多个城市的轨道交通隧道工程的92个实测案例分析,研究隧道工程周边地表最大变形的分布特点。根据线路部位、施工方法、断面形式、场地土类型等方面的不同进行分类,对地表竖向位移的实测结果进行数理统计分析,结合相关研究成果和技术规范要求,给出地表竖向位移控制值的建议数值。隧道工程周边地表竖向位移控制值的影响因素众多,工程实际应深入开展相关研究,以提高隧道工程的安全风险管控水平。
According to study of 92 cases in some cities of China, the ground maximum deformation distribution characteristics surrounding the tunnels was studied. The classification was conducted according to the line location, construction method, cross - section form and soil type. The monitoring measurement results of ground vertical displacements were processed by statistical analysis. With the related research results and technical codes requests, the recommended controlled values for ground vertical displacement were given. The controlled values for ground vertical displacement have many influencing factors, and the in - depth research should be carried out to improve the safety risk control level of tunnel engineering.
