桥梁施工安全事故流变-突变规律

Safety Accident Law of Bridge Construction Based on the Rheology and Mutation Theory

结合桥梁施工事故的特点,通过对流变-突变理论的桥梁施工安全事故规律研究,绘制出桥梁施工安全事故流变规律曲线。建立了桥梁施工安全事故流变-突变数学模型,基于该数学模型采用数学软件MATLAB分析了事故致因与流变突变曲线的关系。对该数学模型进行假设性验证分析,得到起始安全度和衰减系数对事故时间的影响。通过支架结构的施工期变形的监测数据和某次支架坍塌事故实例验证流变-突变数学模型是合理的。

Based on the characteristics of the bridge construction accident,the bridge construction safety accident rheological rule curve was drawn by studying on the theory of rheology and mutation bridge construction safety accident law.The bridge construction safety accident rheology and mutation mathematical model was set up,and the cause of the accident and the relationship between rheological mutation curve was analyzed using the mathematical software MATLAB based on the mathematical model.Initial safety and attenuation rate of accident time effect was obtained by means of verify and analysis on the mathematical model.The rheology and mutation mathematical model is proved to be reasonable,through studying on the deformation monitoring data of support structure during construction.
