[提要]  原位轴压法是现场直接测定墙体承载力的一种微破损检测技术。测得的砌体抗压强度能综合反映砖、砂浆和砌体砌筑质量的影响。本文主要是对测试时的各种影响因素进行了分析。通过大量的对比试验得出了与标准砌体之间强度换算系数的关系、适用范围及工程应用情况。

In-situ axial compression method is a kind of slight-damage test technique to determine, directly insitu, the loading capacity on brick walls. The compression strength of the brick laying, so determined, show its complex influences by the bricks, mortar and the quality of laying. This paper mainly analyses various influential factors from the measurements. A large amount of contrast tests gives the strength conversion coefficient in relation to the standar brick layings and its applicable extent. Finally its applications in practical engineering situations are illustrated.
