摘　　要：由于洪水浸泡,砌体结构的承载能力将会受到影响,甚至出现倒塌.为了掌握不同含水率对砖砌体结构强度的影响规律,确定浸泡后结构的承载能力,有必要对含水率影响砖砌体抗压强度进行研究.通过对不同浸泡时间的砖砌体试件的抗压强度进行测试,对比了不浸泡、浸泡2 d、7 d、14d砖砌体试件的抗压强度,得到了砖砌体试件抗压强度随浸泡时间的变化规律.Bearing-capacity of Masonry will be influenced if soaked in flood,and it may even collapse.Therefore,it＇s necessary to investigate the effects of different water content on compression strength of masonry material to pursue rules how water content influences the characteristics of masonry material,and to determine rational strength of the material.In this paper,experiments are carried out to measure compression strength of brick masonry members under different soaking time.Through comparing their strength of the members with no soaking, soaking to 2 days,7 days and 14 days,some rules of strength development of brick masonry soaked in water are acquired.

关 键 词：砖砌体 含水率 抗压强度 试验分析
