摘要
转体参数测试是桥梁水平转体施工中的重要环节之一,目的是实测体系不平衡力矩、摩阻力矩、摩阻系数、偏心距、配重以及牵引力等。但是转体参数的实测结果受到很多因素的影响。因此结合多年的现场实测经验,研究总结了几种影响因素,为现场快速实测提供了一定的依据。
The rotational parameters test is one of the important steps in bridge horizontal rotation construction.The test is for measuring the system’s unbalanced moment,frictional moment,frictional coefficient,eccentricity,counterweight,traction and so on.However,the measured results are affected by many factors.Based on many years of field measure ment experience,several influence factors,which are studied and summarized in this paper,provides some basis for rapid field measurement.
