城市轨道交通工程施工安全事故聚类分析

为确定城市轨道交通工程施工事故的主要类型,并探究全过程的各种风险因素.针对城市轨道交通工程施工安全事故,提出了基于K-means均值的城市轨道交通工程施工安全事故聚类分析的主要流程,分析验证了安全风险分布的重点阶段与主导因素,同时,确定了城市轨道交通工程施工事故的主要类型.研究可以建立安全风险分布阶段及风险因素基本框架,确定分类变量,形成结构化数据库.

Reliability evaluation of subway operation based on Copula time-dependent model

It is very important to determine the main types of urban rail transit engineering construction accidents and explore various risk factors throughout the process. This paper proposes proposed the main process of cluster analysis of urban rail transit engineering construction safety accidents based on the k-mean method for urban rail transit construction safety accidents, analyzes analyzed and verifies verified the key stages and leading factors of the distribution of safety risks, and at the same time, determines determined the city The main types of construction accidents in urban rail transit engineering. Through the research in this article, this study can establish the basic stage of security risk distribution and risk factors, determine categorical variables, and form a structured database.
