摘　　要：利用振动反问题理论,通过现场无损检测技术,取得砌体结构的动力特性(振型和固有频率)信息,进而建立动力学参数与砌体结构刚度之间的显式函数关系,从砌体结构部件的本构关系建立刚度与强度关系,得出实测强度、墙体承载力以及砌体结构施工质量达到设计指标的程度.进一步可以给出安全性评定,抗侧力能力及优质工程评选的客观依据.In this paper the method is given, combining nondestructive listing technology to obtain the data of structural dynamic behaviors, as the frequences and modes of vibration of masonry building, with theoretical analysis of inverse problem in vibration to form a formula which is a explicit function of relation between structure stiffness and dynamical behaviors, further, obtaining structure testing strength to eveluate the construction quality of masonry building.Comparing testing strength with design strength can eveluate construction quality and design level for masonry structure and give security and lateral resistence of the masonry structure. This method provides a objective scientific basis for comparing and appraising construction quality of the masonry building.
