This article gives a engineering case of CPTU method and laboratory method in soil classification in railway subgrade engineering. In China, soil classification in railway subgrade engineering is often obtained through the traditional laboratory test. With in-situ tests developed in China, CPTU test is used widely in stratigraphy for soft deposit in railway subgrade survey and the National Railway Administration code based on CPTU test is also established. A study is made with a engineering case of subgrade. Two methods are applied in identifying soil strata respectively and differences of them are also discussed.
