A Study On The Tacit Knowledge Integration And Sharing Of Safety Alerting And Emergency Handling In Geotechnical Engineering Projects

On the basis of literature review, expert interview and questionnaire survey, this paper investigates the knowledge integration and sharing in safety precaution and control of geotechnical engineering enterprises, according to the logic sequence of "theoretical foundation-theoretical model construction and empirical study-proposal design-practical testing", with the aid of system theory, cybernetics, information theory, modular theory, institutional economics, and corporate strategy alliance theory.The goal of this paper is to promote the geotechnical engineering enterprises for enhancing tacit knowledge integration and sharing in safety precaution and control. Through serial system institutional design and operational tool development, it is to externalize the tacit knowledge of site managerial experiences and applicable technology of early risk alerting, risk prevention, risk control and emergency handling in numerous engineering projects, and to preserve in a modular way each kind of knowledge of safety precaution, risk control, emergency handling, and to realize sharing of tacit knowledge among different corporate interior projects and among different enterprises with the aid of computer network system. The tacit knowledge integration and sharing enable project administrators or safety personnel, when facing same or similar hidden dangers, to profit from existing handling experience, reduce decision-making time under emergency, increase their early alerting and control ability towards quality safety accidents, and reduce the repeated incurrence probability of same or similar project quality safety accidents among different projects of same enterprise or different enterprises of same profession.1) Through questionnaire survey, expert interview and theoretical inference, the reasons for repeated occurrences of similar quality safety accidents in geotechnical domain are investigated. According to the intrinsic logical path and knowledge management vein between "Safety control performance of geotechnical engineering" and "repeated occurrences of similar quality safety accidents", the responsibility attribution for repeated occurrences of safety accidents is analyzed, by constructing the "responsibility attribution conceptual model" for empirical analysis, which consists of three levels:"tacit knowledge sharing factor"-"tacit knowledge sharing"-"safety control performance"; according to the conceptual model, the research hypothesis is proposed to determine the definition of variables and measurement contents. With the aid of statistical analysis software SPSS 13.0, statistical analysis is carried on to the measurement targets of questionnaire design. Reliability analysis results reflected the consistency of the measurement topics and the well-formedness of internal structure; the validity analysis results showed that the measurement results conform to the theoretical hypothesis; and relevant analysis results showed that the proposed hypothesis is fully confirmed. The empirical study demonstrated:the "tacit knowledge sharing system for safety control" is composed of two systems:"corporate internal sharing system" and "professional corporate sharing system". The tacit knowledge integration and sharing are subject to the influence of "sharing motivation system, organizational institution, corporate sharing culture, tacit knowledge integration and sharing medium". The "motivation system, organizational institution, corporate sharing culture, tacit knowledge integration and sharing medium" all have significant positive influence on the "tacit knowledge sharing system for safety control"; the "tacit knowledge sharing" has significant positive influence on the "safety control performance". The quantitative research results confirmed that the "responsibility attribution conceptual model" is universally applicable and rational.2) according to the confirmed "responsibility attribution conceptual model, with the aid of institutional economic theory, modular theory and strategic alliance theory, studies are conducted separately on the institutional arrangements and realization approaches driving tacit knowledge sharing among corporate interior and professional alliance enterprises. For the obstacles of tacit knowledge integration and sharing among enterprise interior and professional strategic alliance enterprises, corresponding motivation system, organizational institution system and corporate sharing cultural system are designed to drive the tacit knowledge integration and sharing. In view of the difficulty to externalize the tacit knowledge, the paper designed tacit knowledge externalization modular integration model and modular knowledge sharing driving model.3) with the aid of system theory, cybernetics and information theory, the paper identifies the basic functional positioning and development flow and technical route for the "tacit knowledge integration and sharing management system", and develops its application software, including tacit knowledge collection system, tacit knowledge sharing system and knowledge product transaction system, thus providing applicable platform for carrying on tacit knowledge integration and sharing for corporate interior and professional alliance enterprises from technical angle.4) By selecting sample units, the "tacit knowledge integration and sharing management system in safety precaution and control of geotechnical engineering enterprises" is applied and tested from two levels:the institutional arrangements system and the software system, so as to confirm the applicability of the institutional design and software system of the "tacit knowledge integration and sharing management system". According to the testing results, the institutional arrangements and software system are systematically revised and perfected. through institutional system's implementation and software system platform construction, the sample unit enables its safety engineers to preserve and accumulate their intuition, thinking mode and know-how facing related problems. Their tacit knowledge originally unseparable from individuals becomes the knowledge which can be shared by members of the organization, and engineers'successful experiences and failing lessons in early safety alerting and emergency control can be preserved and inherited, reducing and avoiding some accidents of quality securities in common sense.5) Through site interviews, seminars, and questionnaire survey, the commercialization value and market promotion potential of the "tacit knowledge integration and sharing management system in safety precaution and control of geotechnical engineering enterprises" are appraised. The appraisal results demonstrated that this software system has filled a gap in the market, meeting the realistic demands of geotechnical engineering construction enterprises, thus having high commercial development value.
