前支点挂篮行走偏位预防及纠偏措施

摘要

In the walking process of the front-support hanging basket,due to the walking system, such as the asymmetry of side sliding boots,the difference of walking distance and unequal walking speed may lead to deviation.Some problems related to the construction of Malinghe Bridge in this pa-per were deeply discussed,and some reasonable precautions were proposed.%在前支点挂篮行走过程中，由于挂篮行走系统自身的原因，其上、下游两侧滑靴行走不对称或每次行走距离、行走速度不均等将导致行走偏位。文中就马岭河特大桥主梁挂篮施工中行走过程的一些相关问题进行分析，提出合理的纠偏措施。
