Abstract
Through research and analysis conducted by the participants in the construction, operation, design and scientific research of domestic modern trams and the comparison, summary and design, five aspects such as the bedding slope rate design, pavement, safety protection of high and low coverage scope, drainage design and road lap are discussed and optimized, and roadbed standardized cross-sections are recommend. Analysis of railway A, B group of filler applied directly indicates their disadvantages in subgrade engineering and the bed bottom packing with A, B group of gravel, sand soil less than 6 cm should be selected. With a view to the present condition in the design of the existing bridge transition section design, the uneven settlement and the stiffness transition problems, the optimization scheme is put forward.关键词
