摘要
砖混结构砌体的抗压强度是房屋可靠性评定和房屋改造、加固的基本依据。本文介绍一种微破损砌体抗压强度检测方法——原位轴压法,即采用专用液压油缸式扁千斤顶,在现场对砌体抗压强度进行直接原位测定。试验研究及工程实践表明,这种检测方法数据可靠、简便适用。
The compressive strength of masonry walls in existing buildings is the base of reliability estimation for reforming or strengthening of building.In this paper,a micro-destructive method for evaluating compressive strength of brick masonry,i.e.axial compression method in situ is proposed.In this method a special flat jack is used to determine the compressive strength of masonry walls in situ.The experimental results and engineering practice show that the method is convenient for use and the experimental datum arc reliable.
