摘要  文章对地铁区间邻近公路桥风险评估技术进行了研究,提出了以评估结果为基础进行专项设计的理念。首先,在广泛调研和多年工程经验的基础上,结合工程实际辨识出安全风险影响因素,建立以安全为目标的风险评价指标体系;其次,引入层次分析法计算出指标体系各层因素的相对权重,判断出主要风险源;最后,以加固地层、控制地下水、减小对近接建筑物基础影响为重点,从施工方法、工程措施和监控量测三个方面对大连地铁海高区间隧道邻近凌水河二号桥区段进行专项设计。

Abstract:  In this paper, the risk assessment of a metro tunnel near a highway bridge is studied and the concept of specialized design is put forward based on assessment results. Firstly, the safety risk influence factors are identified based on comprehensive investigations and engineering experience, and the risk evaluation index system aiming at safety is established. Secondly, the analytic hierarchy process (AHP) is adopted to calculate the relative weight of each factor in the index system to estimate the main risk sources. Finally, with a focus on ground reinforcement, underground water control, and reducing effects on the adjacent building foundation, a specialized design for the running tunnel section near the Lingshuihe No. 2 Bridge is established in terms of the construction method, engineering measures, and monitoring and measurements. During the construction process, the monitoring data of both the surroundings and the tunnel structure were within the thresholds specified in the control specifications, ensuring construction safety and stability, as well as safe operation of the adjacent highway bridge.
