Monitoring and Analysis of Datum Strand of the Xi Houmen Suspension Bridge

In the construction monitoring and control of the datum strand of Xi Houmen Suspension Bridge,the parameter formula method is adopted to express the relationship between datum strand configuration and related parameter in order to facilitate application in construction control.The monitoring method and application of each parameter in the formula is elab- orated,the readjusting results and stable observations are analyzed as well.It proves the efficiency of construction monito- ring,the correctness of the method,and the reasonableness of parameter adoption.The datum strand reaches the require- ments of adjusting and stable observation.The method can be a reference to other suspension bridges.
