采空区沉陷变形和地震对建筑耦合作用的影响及保护措施
|
摘要
针对采空区建筑抗震抗沉陷变形能力的不足,在分别分析采空区沉陷变形和地震对建筑作用的基础之上,进一步研究分析了采空区沉陷变形和地震对建筑耦合作用的影响,指出通过提高建筑物基础的整体性、加强首层梁柱配筋、采用隔震减震设计、设置可升降点式基础、对建筑物进行变形加固处理可以增强建筑抗震抗变形的能力。
According to the capacity shortage of anti-seismic and resistance to subsidence deformation of buildings on goaf,based on the analysis of the influence of the subsidence deformation of goaf and the earthquake on the building,has a further study on the influence of the subsidence deformation of goaf and earthquake on building coupling. Based on the analysis of the relevant research results at home and abroad,points out that through the following measures can enhance the ability of anti-seismic and resistance to subsidence deformation of buildings on goaf,improve the integrity of the building foundation,strengthen the reinforcement of the first floor beam column,use the seismic isolation design,set up the rise-fall dot foundation,use the deformation strengthening treatment on buildings.
