摘　　要：牵索式挂篮前支点斜拉索索力对挂篮受力有非常重要的影响 ,根据挂篮关键部位的受力限值条件 ,给出了索力范围确定的方法、原理及步骤 ,结合实桥编制计算程序 ,进行数值计算 ,并在施工过程中得到运用。The cable force at the fore support has a very important effect on the force acting on the cable supported form traveler. On the basis of the force limitations for the key parts of the traveler, the principle, method and procedures for the determination of the scope of cable force are given. The computer program for calculations is developed and calculations for actual bridges are made and used during construction.
