There is no such thing. There are three books on soil mechanics in Tsinghua University, namely, Chen's Soil Mechanics 1994 edition and Chen Xizhe's latest edition of Soil Mechanics and Foundation. There is also Li Guangxin's soil mechanics edition. Li Guangxin's preface says that there are traces of Chen, but it is certainly not as good as Chen Classic. This book is a classic textbook of soil mechanics, which has been quoted in almost all soil mechanics books. But the practical book Soil Mechanics emphasizes understanding rather than practice. I have Chen's PDF document of Soil Mechanics, and some other versions of soil mechanics study guides. I don't know if it is possible!
