RESEARCH OF EARLY WARNING SYSTEM OF HYDRAULIC STRUCTURE OF RAIL TRANSIT

摘要

Viaduct is widely used in urban rail transit construction. For the piers and foundations of rail transit bridges constructed in the river or waterway, how to prevent hydraulic disease of them has become an important issue in rail transit construction. In this thesis, the primary concepts of early warning are introduced, and the main factors influencing durability of hydraulic structure of rail transit are analyzed. The early warning analysis on Wenyu River Bridge of the Beijing airport line is taken, and it provides valuable reference for the research on structural durability of rail transit in future.
