摘要
机械法联络通道作为一种新兴的地下结构施工方法,开展监测技术研究对其安全施工具有重要的意义.针对目前工程中监测目标集成度不够、信息化程度不高的问题,以宁波地铁机械法联络通道项目为基础,提出了一套完整的联络通道施工安全在线智能监测系统.该系统分为应用层、传输层、感知层三个部分,并且具有采样、存储、传输、数据处理和预警功能.通过开展缩尺模型试验,测试了联络通道掘进过程中的变形及应力发展规律,并检验了监测系统的可靠性.试验结果表明该系统可实现实时监测、无线传输等目标,满足实际工程的监测需求,可进一步推广至实际工程.
As a new construction method of underground structure,it is of great significance to study the monitoring technology of mechanical connection passageway.Aiming at the problems of insufficient integration of monitoring targets and low information level in current engineering,a complete online intelligent monitoring system for the construction safety of contact channel is proposed based on the Ningbo Metro mechanical contact channel project.The system is divided into application layer,transmission layer and perception layer,and has sampling,storage,transmission,data processing and early warning functions.The development law of deformation and stress during the excavation of the contact channel is tested by scale model test,and the reliability of the monitoring system is verified.The test results show that the system can achieve real-time monitoring,wireless transmission and other objectives,meet the monitoring needs of practical engineering,and can be further extended to practical engineering.
