西安火车站站房建筑幕墙跨地裂缝构造设计及受力分析

Structural Design and Stress Analysis of Curtain Wall of Xi'an Railway Station Across Ground Fissure

地裂缝是西安地区典型的地质灾害,长期以来研究人员对地裂缝区域的建筑设计做了一系列研究,包括地裂缝成因、分布及活动规律,并提出一系列行之有效的防治对策,但是针对铁路旅客站房中建筑幕墙跨越地裂缝的构造措施还未有过相关研究。本项目为西安站改扩建工程,其中f3地裂缝穿越站房及高架候车室拟建场地,将对站房建筑安全造成一定影响。结合项目所处区域工程地质背景构造及相关勘察资料,通过分析研究地裂缝活动对建筑主体的影响,提出一种围护结构的跨地裂缝可行构造措施,将今后地裂缝可能发生的活动对建筑的影响降到最低。

Ground fissure is a typical geological disaster in Xi'an area.For a long time,researchers have done a series of researches on the architectural design of ground fissure area,including causes,distribution and activity law of ground fissure,and put forward a great many effective prevention and control measures.However,there is no relevant research on the structural measures of building curtain wall across ground fissures in railway passenger stations.This project is the reconstruction and expansion of Xi'an railway station.The F3 ground fissure,which passes through the proposed site of railway station,will have certain impact on the safety of station buildings.Combined with the engineering geological background structure and related survey data of the project area,and base on the analysis of the influence of ground fissure activities on the main structure of the building,this paper presents a feasible construction method for the retaining structure across the ground fissure,so as to minimize the impact of the possible ground fissure activities on the building in the future.
