Automatic risk identification and safety early-warning of underground construction under complex conditions

Ding Lieyun,Zhou Cheng

Strategic Study of CAE 2012, Volume 14, Issue 12,   Pages 85-93

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.

Identification of structural parameters and boundary conditions using a minimum number of measurement

Ali KARIMPOUR, Salam RAHMATALLA

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 6,   Pages 1331-1348 doi: 10.1007/s11709-020-0686-4

Abstract: This article proposes a novel methodology that uses mathematical and numerical models of a structure to build a data set and determine crucial nodes that possess the highest sensitivity. Regression surfaces between the structural parameters and structural output features, represented by the natural frequencies of the structure and local transmissibility, are built using the numerical data set. A description of a possible experimental application is provided, where sensors are mounted at crucial nodes, and the natural frequencies and local transmissibility at each natural frequency are determined from the power spectral density and the power spectral density ratios of the sensor responses, respectively. An inverse iterative process is then applied to identify the structural parameters by matching the experimental features with the available parameters in the myriad numerical data set. Three examples are presented to demonstrate the feasibility and efficacy of the proposed methodology. The results reveal that the method was able to accurately identify the boundary coefficients and physical parameters of the Euler-Bernoulli beam as well as a highway bridge model with elastic foundations using only two measurement points. It is expected that the proposed method will have practical applications in the identification and analysis of restored structural systems with unknown parameters and boundary coefficients.
