摘　　要：随着社会经济的发展,老旧小区的改造越来越频繁,如何精确地检测出砌体的抗压强度,为后期改造提供参考依据就显得非常重要。文中采用贯入加回弹法与原味轴压法分别对常规条件下某砌体墙试件抗压强度进行检测,通过对两种方法检测出的砌体强度关系进行比对分析,并根据原味轴压法检测结果对贯入回弹法检测的砌体强度进行修正,对今后采用贯入加回弹法检测既有老旧砌体抗压强度工作具有重要的指导意义。With the development of social economy,the transformation of old residential areas is more and more frequent.How to accurately detect the compressive strength of masonry and provide reference basis for later transformation is very important.In this paper,the penetration plus rebound method and the original axial compression method are used to test the compressive strength of a masonry wall specimen under conventional conditions respectively.Through the comparative analysis of the relationship between the masonry strength detected by the two methods,and the masonry strength detected by the penetration plus rebound method is corrected according to the test results of the original axial compression method,It has important guiding significance for testing the compressive strength of existing old masonry by penetration and rebound method in the future..

关 键 词：老旧砌体结构 砌体抗压强度 贯入加回弹法 原味轴压法
