Abstract:The representative strong rotten clay stone and marlstone rock samples with undisturbed and disturbed state are selected at the Xinxiang Luwangfen test zone in Middle-Route of the South-to-North Water Transfer Project.Through a series of soil mechanics experimentation the physical and mechanical character of swelling rock has been well studied and supply scientific reference for the design and construction of swelling rock slope in Middle-Route of the South-to-North Water Transfer Project.

Key words:swelling rock;swelling stress;swelling ratio;strength index;initial tangent modulus
