Technical Features of Commonly-Used Span Bridges for Passenger Dedicated Railways

The current construction of passenger dedicated railways pushes forward the development of the global techniques for construction of railway bridges and to some extent, also demonstrates the development trend of the bridges under high-speed railway conditions. To carry out the construction of the passenger dedicated railways in a more scientific and rational way in the future, it is quite necessary to sum up the experiences and to make the system tests in the construction process in order to form a complete set of fairly perfect theories and techniques for the construction of the bridges under the said conditions. In this paper, the features of design and construction of the commonly-used span bridges for the passenger dedicated railways are dealt with.
