Research methods: Based on the subgrade settlement control design of the experimental section of Beijing-Tianjin intercity railway, the rational design program is worked out through making demonstrations in technology and economy.
Research results: Because the cost of settlement control for higher embankment of thick compressible subgride is relatively high, retaining structure which usually increase the engineering cost in common design now become a method to save engineering investment.
Research conclusions: To adopt retaining structure in settlement control for higher embankment of thick compressible subgrade can save money, occupy less land and make the construction environment beautiful on the basis of improving the reliability of settlement control.
