Abstract
The soft subsoil had a wide distribution in Yingkou Coastal Industrial Base Railway, so cement mixing pile was used to reinforce the subgrade. In order to ensure the construction quality, to improve work efficiency and to achieve economical and reasonable design scheme, pile experiments and inspections were carried out on DK17+300 subgrade. Through inspection and data analysis on 24 pile groups in different parameter and arrangement patterns, the appropriate mixing proportion and the arrangement patterns of pipes were put forward, so as to serve as a guidance for its design optimization.关键词
