（國家地震局工程力學(xué)研究所 哈爾濱 150080）[提要] 利用振動反問題理論，通過現(xiàn)場無損檢測技術(shù)，取得砌體結(jié)構(gòu)的動力特性（振型和固有頻率）信息，進(jìn)而建立動力學(xué)參數(shù)與砌體結(jié)構(gòu)剛度之間的顯式函數(shù)關(guān)系，從砌體結(jié)構(gòu)部件的本構(gòu)關(guān)系建立剛度與強(qiáng)度關(guān)系，得出實測強(qiáng)度、墻體承載力以及砌體結(jié)構(gòu)施工質(zhì)量達(dá)到設(shè)計指標(biāo)的程度。進(jìn)一步可以給出安全性評定，抗側(cè)力能力及優(yōu)質(zhì)工程評選的客觀依據(jù)。
[關(guān)鍵詞] 砌體結(jié)構(gòu) 施工質(zhì)量 無損檢測 振動反問題In this paper the method is given, combining nondestructive testing technology to obtain the data of structural dynamic behaviors, as the frequences and modes of vibration of masonry building, with theo-retical 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.
