【摘要】：隧道結(jié)構(gòu)健康是判斷隧道安全的重要指標,因而對隧道結(jié)構(gòu)健康監(jiān)測和評估是隧道安全管理的主要手段。本文針對隧道多為長距離、大范圍的惡劣環(huán)境以及圍巖-結(jié)構(gòu)自身復雜性,使得傳統(tǒng)的方式無法滿足隧道實時、快速、連續(xù)的監(jiān)測要求的情形,構(gòu)建了由采集層、傳輸層、基礎(chǔ)層和應(yīng)用層完整的4層框架組成的隧道結(jié)構(gòu)健康監(jiān)測信息化系統(tǒng),并采用光纖光柵技術(shù)進行數(shù)據(jù)采集;通過隧道結(jié)構(gòu)健康監(jiān)測信息化系統(tǒng)的設(shè)計與應(yīng)用,驗證了實時、在線、連續(xù)隧道參數(shù)監(jiān)測系統(tǒng)的穩(wěn)定性和可靠性,并實現(xiàn)了隧道安全信息化監(jiān)測預(yù)警功能,同時基于應(yīng)變和裂縫位移連續(xù)監(jiān)測數(shù)據(jù)的分析,可為后續(xù)隧道系統(tǒng)安全評定、控制措施制定提供數(shù)據(jù)支持和理論依據(jù)。
[Abstract]:Tunnel structure health is an important index to judge tunnel safety, so monitoring and evaluation of tunnel structure health is the main means of tunnel safety management. In view of the fact that tunnels are mostly long distance, large scale environment and complex surrounding rock structure, the traditional methods can not meet the requirements of real-time, fast and continuous monitoring of tunnels, and a collection layer and a transmission layer are constructed in this paper. The information system of tunnel structure health monitoring is composed of four layers frame of foundation layer and application layer, and the data is collected by using fiber Bragg grating technology, which is verified by the design and application of tunnel structure health monitoring information system. The stability and reliability of the on-line and continuous tunnel parameter monitoring system are realized, and the monitoring and warning function of tunnel safety information is realized. At the same time, based on the analysis of the continuous monitoring data of strain and crack displacement, it can be used to evaluate the safety of the subsequent tunnel system. Control measures to provide data support and theoretical basis.
