Discussion on vertical deflection monitoring of long-span continuous beam of intercity railway
In order to solve the problems that the original monitored bridge deck points cannot be ob-served normally and conventional leveling cannot be implemented during the disease control process of large-span continuous beams in intercity railways operation,this paper proposes a method of using con-tinuous beam ventilation holes to set monitoring signs and high-precision intelligent total station trigo-nometric elevation method to collect monitoring data for the vertical deflection monitoring of large-span continuous beams in intercity railway bridges.This method is proved by the vertical deflection monitoring test during the operation and reinforcement of a large-span continuous beam in an intercity railway to have such advantages as simple point layout,high operation efficiency,and it can be used to accurately measure the changes in vertical deflection of continuous beams during operation and mainte-nance without interrupting train running.It provides reliable monitoring information for the operation and reinforcement of continuous beams.
