摘　　要：采用试验与理论计算对比的方法,考察抱杆在起吊、竖直、倾斜时不同荷载状态下的应力。通过试验结果分析,指出该类抱杆的结构薄弱部位,为类似抱杆的设计、施工提供参考。同时将试验结果与有限元计算结果进行对比分析,结果表明该类抱杆具有优良的力学性能。Contrast testing was done to evaluate the stress of a holding pole under lifting, vertical and inclining loads. The weak position of the holding pole was pointed out by the analysis of the test results, which may be used as references for later design and construction. And the results of the tests were compared to those by FEM. The results indicate that the holding pole has excellent mechanical performance.
