Research On Safety Design Of Medium Cruise Residential Area Integrating Fire Control And Evacuation

With the rise of cruise tourism,people have begun to choose cruise ships as entertainment and leisure destinations in order to pursue a higher quality of life.However,potential fire safety problems hinder the development of cruise tourism.By exploring reasonable cruise safety guarantees The design method can greatly avoid the risk of fire and other accidents,and improve the safety evacuation and survival probability of personnel after the accident.This paper takes the fire evacuation safety design of medium-sized cruise passengers as the research direction,and uses fire numerical simulation and evacuation simulation method based on passenger intelligence to construct a cruise passenger safety assurance index that integrates fire protection and evacuation to evaluate the feasibility of the safety design scheme.Firstly,the fire process and fire products of the cruise ship are analyzed,and the characteristics of the cruise ship fire are summarized;the evacuation model and evacuation influencing factors are expounded,and the judgment standard for safe evacuation is determined;the layout of various passenger cabins and evacuation passages of the research object is developed a preliminary analysis.Then,taking the residential area of medium-sized cruise passengers as the engineering background,three fire condition scenarios were set up according to the location of the fire source,and the fire model of the residential area of the medium-sized cruise ship was established by Pyro Sim fire simulation software.The time-varying risk index parameters were observed,and the Available Safety Egress Time(ASET)under each fire condition was determined according to the time when each risk index parameter reached the critical value.Then,using Anylogic software as the evacuation simulation platform,based on the customized passenger agent,the evacuation scene of the passenger living area of the medium-sized cruise ship was simulated,and the function code was used to control the definition of the agent’s attributes,so as to realize the generation of the passenger agent’s regional distribution,age and gender.The precise setting of the type and the corresponding evacuation speed interval makes the entire evacuation process closer to the real situation.Finally,according to the simulation results,the Required Safety Egress Time(RSET)corresponding to each fire condition is obtained.Finally,starting from the layout of fire fighting equipment and the modification of evacuation stairs,three safety design schemes were completed,and fire simulation and evacuation simulation were carried out again for the three schemes;at the same time,the fire safety assurance degree and evacuation safety were defined.Based on the concept of security degree,an evaluation index of cruise passenger security degree that integrates firefighting and evacuation is constructed.Reasonable evaluation and selection of three safety design schemes are carried out.The results show that scheme 2 not only meets higher safety performance requirements,but also reduces the amount of equipment configuration compared with scheme 1,and has higher cost performance.It is a comprehensive and better medium-sized cruise ship Fire evacuation safety design scheme for passenger living area.The speed interval assignment method of passenger agent proposed in this paper can more accurately solve the problem of single speed setting of different types of pedestrians in evacuation simulation,and can restore more realistic personnel evacuation scenarios,and the concept of cruise passenger safety indemnification can provide a certain reference value for the safety design researchers of the cruise living area.
