high-speed railway tunnel-Zhengwan high-speed railway and the rationality of this method has been verified through the data of field test. Key words: rock mass classification; support pressure; deep..., the proposed empirical calculation method is applied to the support pressure calculation in Zhengwan high-speed railway, Hubei province, China. Table 1 Summary of various empirical methods for support pressure......
