基于灰色关联理论的地铁施工安全评价模型研究及应用

地铁施工安全是一个涉及多因素、多层次结构的非线性系统,通过对影响地铁施工安全的因素分析和灰色关联理论在地铁施工安全评价中的适用性分析,构建了灰色关联理论分析方法的地铁施工安全评价模型,通过对非线性、离散性以及动态性的地铁施工安全数据进行量化分析和评价,根据关联度大小判断地铁施工的相对安全程度,并运用模型对天津市在建地铁的施工安全状况进行实际验证,评价结果与实际情况相符。该方法为地铁施工安全定量化评价和多目标决策问题提供了新途径,可作为地铁施工相对安全等级划分的重要理论依据,具有实用性和可行性。

Application of Safety Evaluation Model of Subway Construction Based on Gray Correlation Theory

Construction safety of subway is a nonlinear system involving multi-factor and multi-level structure. By analyzing the factors affecting the safety of subway construction and the applicability of the theory of grey correlation in subway construction safety assessment analysis,a safety evaluation model of subway construction is built based on grey correlation theory. Through quantitative analysis and evaluation of the non-linear,discrete and dynamic data of the subway construction safety,according to the degree of association to determine the relative safety of subway construction,the model is used to verify the actual situation of the safety of the subway under construction in Tianjin. The result is consistent with the actual situation. This study provides a method for the quantitative evaluation of subway construction safety and the multi-objective decision-making problem,and can be used as an important theoretical basis for the classification of the relative safety of subway construction,with the practicality and feasibility.
