Abstract
To make a study on the anti-sliding stablity of foundation of hydraulic structures on subbed soils, and based on the result by anti-sliding tests of dragged concreting clip plates in foundation pits, the anti-sliding stablity of foundation on subbed soils was determind. There are 3 different forms of largest displacement with 8 different forms of silding move of subbed soils caused by the different maximum compressive stresses of eccentric loads on them. It is worked out a design method to determine the sliding frictional resistances and the forms of sliding moves of foundation subbed soils; a formula for the integal frication resistance to sliding for the structure;a formula for the the anti-sliding move of subbed soils and a rule to distinguish the plane sliding move of foundation subsoils with others. To analyze 3 structures which have been established provides a confirmation with the reality for the design method.
