In order to promote the application of isolation technology in high-speed railway construction,this paper analyzes the economic effects of isolation technology on small and medium-sized station buildings in high intensity area.Taking a typical railway station building as an example,the general seismic structure and isolation structure models under various seismic intensity conditions are established,and the law of the change of main material consumption under different conditions and the factors affecting the cost increase and decrease are analyzed.The results show that the civil construction cost of the isolated building is slightly higher than that of the general seismic building,and the increase range is 5%.The seismic intensity and the area of the first floor have a great influence on the cost of the isolated building.This paper analyzes the advantages of seismic isolation design for small and medium-sized station buildings in high intensity area from the perspective of comprehensive economy,and puts forward the applicable conditions of seismic isolation design for station buildings:high seismic intensity,small bottom area,no less than 2 floors,good geological conditions,line side station buildings with basement,station buildings in high fill area are also very suitable.The relevant research data presented in this paper can be used as reference for decision-making and design personnel of relevant departments.
