Study on emergency rescue material demand and optimal site selection for gas pipeline leakage and explosion
To study the demand for emergency rescue materials and optimal rescue point selection after a gas pipeline leakage and explosion,this paper uses a Case-Based Reasoning(CBR)method to establish an emergency resource demand model for gas pipeline leakage and explosion accidents,and conducts a case study of a gas pipeline leakage and explosion accident in a chemical industrial park.Firstly,this paper collected key elements of historical accidents such as the number of casualties,affected area,and accident grade and unified their dimensions.MATLAB programming is used to determine the source case with the highest similarity to the target case and obtain the proportional reasoning calculation of the emergency resource demand of the target case.Secondly,this paper used the functions of ArcGIS visualization and spatial network analysis to perform buffer zone overlay analysis on the distribution structure of explosion release sources and roads in the industrial park.Meanwhile,ArcGIS interpolation analysis method is used to obtain the risk distribution map of gas explosion accidents in the park,and the comprehensive accident risk map is divided into five levels using natural breakpoint segmentation.The intersection of the erased and merged buffer zone and the high-risk area of gas is the initial location for emergency rescue.Finally,this paper established a network spatial data set to allocate rescue points for high-risk areas in the initial location.Taking into account road conditions and individual differences,six accident emergency rescue points were set up in the industrial park.A range within 5 km was considered an effective rescue range to ensure that emergency supplies can be supplied on time.The results show that the chemical industrial park can optimize the selection of emergency rescue sites by obtaining the demand for emergency resources from historical data on emergency rescue,and by using ArcGIS to establish emergency resource location allocation points and determine the number of rescue points.
