摘要
通过SAA技术在成兰铁路茂县隧道斜井大变形地段的成功应用,对SAA工作原理、SAA技术用于隧道工程监控量测的测点布设、监测数据表达方式、误差及自动监测预警等进行了全面解析和介绍。SAA监控量测技术对比传统的隧道监控量测技术具有高度自动化、信息化及实时性的特点,该技术的成功应用是隧道围岩量测技术的一次重大突破,对强化隧道监控量测过程管理,降低施工安全风险起到积极作用。
The SAA （Shape Accel Array）technology has been successfully used in the monitoring of the serious deformation section of the inclined shaft of Maoxian Tunnel on Chengdu-Lanzhou railway.In this paper,the working principle of SAA,the layout of monitoring points,the interpretation of monitoring results,the error and automatic warning are presented and analyzed.The study shows that compared to conventional tunnel monitoring technology,SAA technology is more automatic,informationalized and timely.The paper can provide reference for management of tunnel monitoring and safe construction.
