Research On Construction Safety Risk Management Of Comprehensive Pipeline Corridor In W City Based On Social Network Analysis Method

Underground integrated pipeline corridor can realize the intensive integration and unified management of all kinds of municipal pipelines in the underground space of the city,eliminate the "spider web in the air","road zipper" and other urban dilemmas,help to enhance the level of urban modernization and improve the life of residents.In today’s urban modernization in China,its construction has attracted the attention of relevant government departments.However,due to the complexity and uncertainty of the urban underground construction environment,construction safety accidents can easily occur during the construction process,causing significant losses.Therefore,it is of great significance to establish an underground integrated pipeline corridor construction safety risk management system.This thesis uses the social network analysis method to carry out the research of safety risk management of underground integrated pipeline corridor construction,which helps to analyze the connection between risks internally,evaluate the degree of risk impact,achieve effective risk control,and then help to solve the safety risks in urban underground integrated pipeline corridor construction.First of all,this study based on the mechanism of construction safety risks of the integrated pipe corridor,the causative analysis of the types of safety accidents,while using the hierarchical holographic model of the construction safety risk elements of the integrated pipe corridor to conduct a comprehensive,multi-angle analysis,to obtain a list of primary risk elements,and then there are experienced experts on the project to filter and filter the first identified risk elements according to the actual situation of the project,so as to A more realistic risk index system was constructed,covering five aspects: personnel,material and equipment,technology,environment and management.Secondly,the relationship data of risk factors were collected through an online questionnaire to construct and visualize an adjacency matrix of the underground integrated pipeline corridor construction safety network.Based on social network analysis method,using block model,intermediate centrality of points and intermediate person analysis,core risk factors are identified.Meanwhile,the key risk relationships are identified using the intermediate centrality of lines.Finally,according to the identified core risk factors and key risk relationships of the urban underground integrated pipeline corridor construction safety analysis,put forward targeted risk control measures.This paper identifies the risk factors at a deep level through the hierarchical holographic model method,and then considers the inner connection between the risk factors through the social network analysis method.According to the principle of "blocking the source,cutting off the path and controlling the impact",the results show that the risk has been effectively controlled and the method is effective,which provides a certain reference value for the subsequent research on the safety risk management of integrated pipe corridor construction.
