Study On Vibration Response Of High-rise Buildings Cased By The Drilling And Blasting In Chongqing Metro

With the economic development of western China, in 2008. Chongqing enters the era of subway construction,。Because the city of Chongqing is on the foundation of the rock, the method of drilling and blasting is used in the process of subway the construction. And Chongqing is a big mountain city, in which there are many high-rise buildings, bridges aspect, so when using drill and blast method, it is bound to consider the vibration response of the high-rise buildings about the drilling and blasting.This paper takes the Wulidian section of Chongqing Metro Line 6 as background, and makes the vibration response of the surrounding high-rise buildings about hole drilling and blasting as the research object. By MAIDAS-GTS, three-dimensional solid model of the relevant is created. And the speed, acceleration, displacement vibration displacement charts of different floors in Surrounding buildings is extracted.And the impact of different geological conditions, different lithology, different slope angle and other factors on the vibration of the building in the process of tunnel blasting is analyzed.Preliminary study shows, when using drill and blast in Process of tunnel construction in the mountain city of rock foundation, the relationship between vibration of the high-rise buildings and floor, driving scale, lithology, slope and other factors is analyzed. It provides a reference for the future project.
