Abstract
As a high-risk subindustry involved in construction projects, highway construction safety has experienced major developments in the past 20 years, mainly due to the lack of safe early warnings in Chinese construction projects. By combining the current state of early warning technology with the requirements of the State Administration of Work Safety and using case-based reasoning (CBR), this paper expounds on the concept and flow of highway construction safety early warnings based on CBR. The present study provides solutions to three key issues, index selection, accident cause association analysis, and warning degree forecasting implementation, through the use of association rule mining, support vector machine classifiers, and variable fuzzy qualitative and quantitative change criterion modes, which fully cover the needs of safe early warning systems. Using a detailed description of the principles and advantages of each method and by proving the methods' effectiveness and ability to act together in safe early warning applications, effective means and intelligent technology for a safe highway construction early warning system are established.
Highlights
China is currently one of the top infrastructure investors in the world
(1) By using analogical reasoning-based case-based reasoning (CBR), this paper gives a basi schematic for solutions to safe early warning technologies by practically solving the three-key issues of index selection, accident cause association analysis, and warning degree forecast, which penetrate the whole process of safe management
(2) Combined with the characteristics of highway projects, as well as the possible problems in the process of data processing, this paper introduces association rule mining, support vector machine classifiers and variable fuzzy qualitative and quantitative change criterion modes in order to keep the data of high fidelity
Summary
China is currently one of the top infrastructure investors in the world. From zero highway breakthroughs in 1988 to the 74,100 kilometers of highway traffic mileage implemented by the end of 2010, comprising the second greatest highway network in the world; China has achieved a level of development that took western countries over 40 years to accomplish in only 22 years, realizing a historic breakthrough in highway construction. With improved knowledge and concern for safety issues, the industry began to see that the occurrences were more or less related to incidents and had their own laws and features Because it has gotten a late start, the study of safety management in China is only an initial attempt in terms of both theory and practice, with imperfect on-site safety management materials, an indirect and hysteretic quality to safety effectiveness, and widespread uncertainties in construction projects. The accident losses during highway construction in China over the past 20 years have been caused mostly by the lagging study and practice of safe early warning; improving early warning abilities and preventing safety issues are the industry’s most challenging tasks
