光纤光栅监测系统在码头混凝土主体结构中的应用

码头工程全寿命周期设计具有重要意义,监测已建工程使用中的安全状态是开展全寿命周期设计理论研究的基础工作之一。在大连某原油码头混凝土主体结构建设过程中,根据结构应力分布特点,选择重要位置埋设光纤光栅监测系统,可实时观测结构应变状态,对于验证和完善现有设计理论,建立结构全寿命周期安全设计理论,并在此基础上建立码头结构预警机制具有重要的推广意义。

Application of FBG monitoring system in the main structure of concrete

The life cycle design in wharf project is very important, and it is one of the basic work for the theoretical research on the life cycle design to monitor the safety state in operation of existed works. In a crude oil terminal project of Dalian, according to the structure stress distribution, we laid the fiber bragg grating (FBG) monitoring system at important positions to observe timely the structural strain in the construction process of the main structure of concrete. It is of great significance for the validation and optimization of current design theory, building of the life cycle safety design theory, and establishment of the early warning system for the wharf structure.
