本文介绍预应力安全壳1:1模型试验中大吨位曲线钢束两个阶段的试验研究。第一部分镦锚体系的试验证实了:在影响曲线束摩擦系数的各项因素中,润滑剂起了决定性的作用。同时通过对比找到了既经济又实用的润滑剂。第二部分介绍钢绞线体系的试验情况,并指出该锚具锚固能满足国内规范要求。
This paper presents the experimental study of the two stages of the large tonnage curve steel beam in the 1: 1 model test of prestressed containment. The first part of the upsetting anchor system tests confirmed: Lubricants play a decisive role in the various factors that affect the friction coefficient of the curve. At the same time by contrast to find both economical and practical lubricant. The second part introduces the experimental situation of strand system, and points out that the anchor can meet the requirements of domestic norms.
