PDL Bridge Settlement Displacement Measurement & Control Technique

Bridge settlement displacement control is one of the major tasks of quality control for passenger dedicated line. It is of radical importance to bearing capacity of bridge and to the control of railway operation performance. This paper, based on the bridge construction of Zhengxi passenger dedicated line, mainly expatiates on the methods of bridge settlement meas urement & control, so as to test and verify the rationality of the design and construction. Finally, some suggestions are pro posed, which may be used as reference for other similar works.
