后装拔出法推定结构混凝土强度试验研究

“Post-installation and PulI-out”Method for Detecting the Strength of a Concre ee Concrete Structure

后装拔出法是检验混凝土抗压强度的一种新方法。试验表明混凝土抗拔力与混凝土抗压强度之间具有良好的线性相关关系。该法操作简单、方便、成本低,可随时用在已建成的新、老结构物上。这一方法的推广应用还有待工程实践进一步认证。

'Post-installation and pull out' method is a new technigue used for detec-ting the strength of a concrete structure. Tests indicated that the pull-out force to the concrete bore a linear relationship with the compressive strength of concrete. This method has the advantage of simple and convenient operation, with considerably low cost, and may be used for detecting any new or old concrete structures at any time. In regard to its widespread application, it requires to have more engineering practice in order to meet with universal recognition.
