Analysis on Monitoring Scheme for Bearing Platform Cofferdam in Bridge Engineering
Taking Dongjiang Extra-large Bridge as the research object,according to the characteristics of the engineering,the monitoring purpose and content of the bearing platform cofferdam are put forward.The field monitoring method is adopted to implement the whole process monitoring of the steel sheet pile cofferdam,and the monitoring early warning value is set.When the monitoring data exceeds the early warning value,it indicates that the structural safety of the cofferdam is threatened,and corresponding measures need to be taken to solve the problem.The research results show that the monitoring of the bearing platform cofferdam can find out the potential safety hazards in the construction in time,avoid safety accidents.
