摘要
桥梁转体施工成败的关键在于转体结构的安全及转体的顺利进行和精确到位。而要做到这一点,必须在转体前对转动体进行称重试验。文章结合石家庄市环城公路跨石太铁路分离式立交桥主桥转体斜拉桥的转体施工,对转动体不平衡力矩、摩阻力矩、偏心距及转动球铰静摩擦系数的实验测试进行探讨分析。
Bridge swivel construction the key to success lies in the twist structure of the safety and smooth swivel, and exact place. To accomplish this ,the weighing test before the twist on the rotating body. In combination with twist construction of cable-stayed bridge in Shijiazhuang city ring road cross-Shijiazhuang-Taiyuan Railway separate overpass torque on the rotor imbalance, friction torque, eccentricity and turn the static friction coefficient of ball joints,laboratory tests to explore analysis.
