Study on Optimum Methods for Large Canal Slope

Abstract:

Aiming to characteristics of large canal slope, the key problem of slope optimization for large canal was studied, and synthetic optimization methods of canal slope were put forward: 1. Enough geological exploration and geotechnical test are beneficial to determine shear strength parameters accurately and to prevent conservative design. 2. Appropriate slope stability analysis method of large canal was chosen, and anti-sliding stability of canal slope accurately was evaluated considering the effect of canal stage excavation and large board concrete liner on canal slope stability. 3. The whole canal slope optimization was embodied through controlling the anti-sliding stability safety factor affluence of canal slope. 4. Based on permissible minimum slope gradient and practically economic cross-section of canal, an optimization method of canal slope was put forward considering slope stability and minimum cost. In addition, concept of permissible limited state and permissible limited gradient for canal slope were proposed.
