Abstract:Research purposes: In recently years,the various structure health monitoring systems have been used in the civil engineering projects and the engineering projects,such as bridge engineering and hydraulic engineering with the rapid developments of sensor technology,data collection technology and test analysis technology. However,there is a little study on monitoring the health of the tunnel structure because of complexity and uncertainty of surrounding rock structure and the load bearing situation.
Research conclusions: From the study,the following conclusions can be obtained: ( 1) The complete tunnel structural health monitoring system ( TSHMS) should be composed of the data collection & transmission system,data analysis & processing system and structural safety evaluation & alarm system. ( 2) Through the analysis of mechanical evolution characteristics of the tunnel structure,the basic idea is presented that the long - term monitoring of the stress characteristics of the secondary lining should be especially conducted. ( 3) According to the complexity and indeterminacy characteristics of tunnel engineering,the fuzzy comprehensive evaluation means is introduced on the base of the conventional safety evaluation system. ( 4) With application of the concepts mentioned above in the super - long tunnel engineering of the Cangling highway,a preliminary TSHMS is established and the evaluation results are basically consistent with the actual situation,so this system is reliable.
