摘要
城市地铁盾构收敛监测是对隧道衬砌管片直径进行观测的方法,可以有效观测出施工过程中衬砌的相对变化趋势。地铁垂直位移监测则着眼于隧道在垂直方向上发生的刚性绝对位置沉降的变形。结合某市地铁盾构隧道的实际监测工程实例,研究了这两种监测项目的具体施工方法和技术要求,并针对某一具体案例综合分析了监测对象的变形情况,为类似工程监测提供一定参考。
The diameter of tunnel lining segment is measured in convergent monitoring of subway shield tunnel,and the relative variance is detected efficiently.The absolute rigid vertical deformation in subway tunnel is noted in settlement monitoring.Specific construction and technical requirement of the two methods of monitoring is researched based on the engineering example of the subway in a city.According to the monitoring record of one stage,studied the concrete construction methods and technical requirements of these two kinds of monitoring projects,and the deformation of the monitoring object is analyzed in a specific case,which has a certain reference value for the similar engineering monitoring.
