施工缝预留方法的试验研究

The Experiment Study on the Method of Providing Construction Joint

施工缝的预留位置及处理方法一般应按规范进行,但当偶然原因作用使得施工缝不能留在预先规定的地方时,结构的强度可能不满足要求。本文针对这一问题,对施工缝的预留方法进行了一批对比性试验。通过试验,得出一些可以提高施工缝强度的规律和定量的概念,可供施工时参考。

Providing ang dealing with the construction joint may usually be made depending on building code.But when construction joint can not be set up in the exact place under the accidental reasons,structural strength may don＇t meet requirments.In the paper,a series of experiments were made on providing construction joint.From the experiments,some rules and concepts that can improve strength of construction joint were found and may be used in the construction.
