Supporting and high-speed railway embankment design
Abstcact：With the rapid development of China's high-speed railway, after the high-speed railway foundation requirements, thus reinforcing the roadbed in construction it is particularly important. High-speed railway subgrade settlement after construction very strict control, subgrade after construction settlement mainly residual settlement after the completion of the railway track laying foundation settlement control in order to meet our high-speed railway embankment after construction requirements, the need to choose the right foundation settlement calculation method selecting appropriate foundation reinforcement measures in accordance with the settlement calculations. Before designing high-speed rail access to a lot on design specifications, and according to the specifications of the embankment design process, according to the mission statement of requirements designed retaining wall, and checking whether its stability to meet the requirements, the design of the pile retaining plate complete wall reinforcement, the last of the high-speed railway embankment design time to start on.
