Abstract
One of the most important problems in safety management of metro construction is the insufficient collection and usage of construction safety information, so that the safety control of metro construction is still “in the black box”. Therefore, the presented research applies information technology to safety control of metro construction, which includes: a. For safety risk identification before construction, we proposed a novel approach to automatically identify construction safety risk out of engineering drawings with information technology. Then the safety knowledge of metro construction could be accumulating, sharing and reusing more accurate and effective. b. For risk early-warning during construction, we brought up an approach based on safety risk information fusion and temporal-spatial coupling for metro construction, which is able to effectively identify and track dangerous construction process and locations dynamically. c. For special sections of high risk, we developed the integrated control techniques of automatic monitoring and real-time early-warning for metro construction. The system send any early-warning information to construction workers on site, so that controlling methods and emergency moves can be applied in real time to ensure construction safety. The research achievements are successfully applied in the metro construction in Wuhan, Shenyang, Kunming, Zhengzhou, etc. in China.
