| Abstract: | A stretch,by the length of 135 km. of the main canal of middle route south to northwater transferring project in China cuts through dilatable soil area. The dilatable soil mass has super-consolidation property and a great many fissures developing randomly in all directions. This soil con-tains some hydrophilic mineral, and is broken down into very small blocks of irregular shape. Theshear strength of the dilatable soil mass depends mainly on the degree of fissure development and stateof the fissure face. The method for determining the shear strength of the dilatable soil, relevant pro-tection and treatment of such a soil slope and stability analysis are introduced in this paper. |
