摘要
本文通过在圆钢管表面上钻盲孔来检测构件上某点的表面工作应力,了解钻孔后孔周应变的释放情况,弄清不同受力状态和不同表面应力分布情况下的钻孔释放规律,通过试验来掌握该法的适用情况及影响参数,并结合相关理论研究在役压弯钢管构件的内力识别问题。
In this paper,the surface work stress of the steel tube was detected by drill blind hole which will make us to know the situation of strain release after drilling the hole,and will understand the release regular on different force status and different surface stress.Unified the correlation theories research,we will study the problem about internal force identification of press-bend steel tube by test.
