换索施工顺序和换索数目对梁塔内力的影响分析

摘要

Combining with the engineering situation of a bridge,this paper established the bridge plane bar system model and made simulation and calculation,combining with theoretical calculation and practice measurement,analyzed the influence of cable replacement construction se-quence and number to different beam and tower internal forces,gave the best construction sequence and cable replacement number to medium and small span cable-stayed bridge cable replacement.%结合某桥梁的工程概况，建立了桥梁平面杆系模型并进行模拟计算，将理论计算和实践测量相结合，分析了换索施工顺序和换索数目的不同对梁塔内力的影响，给出了中小跨径斜拉桥换索的最佳施工顺序和换索数目。
