Design and Research on Structural Health Monitoring System for Roof and Yungu Arch of Hangzhou West Railway Station
Hangzhou West Railway Station is a super-large railway passenger station.The steel roof of the passenger station adopts a truss-net combined structural system,and the cloud valley adopts an arch-supported suspension structure.The force transmission paths of the two structural systems are complex,and the structural stress state during the construction process is difficult to grasp.The structural health monitoring technology can grasp the stress state of the roof and Yungu arch structure in real time,which is an important means to ensure the structural safety during the construction and operation period.In this paper,a design scheme of structural health monitoring system for Hangzhou West Railway Station combining construction period and operation period is proposed.The monitoring objects include three categories:structural integrity,components,loads and environment.By erecting cloud server nodes during construction,the system is integrated into the intranet management and control platform to ensure the normal operation of the system during the operation stage.At the same time,aiming at the structural monitoring object of Hangzhou West Railway Station,this paper puts forward the safety assessment scheme of structural health monitoring,and sets the early warning threshold respectively to realize the safety early warning and state assessment of the structure.
