INTERACTION OF SOIL MASS AND BUCKET FOUNDATION UNDER HORIZONTAL LOADS

The interaction between soil mass and bucket foundation under horizontal loads is analyzed. The equilibrium equations of forces and moments on a single and a quadruple bucket structure are formulated. The relation of lateral displacement of bucket top with horizontal loads is obtained based on a soil-spring model. The results of the bucket top displacements are compared with the three-dimensional finite element results. Good agreement is achieved. In addition, the safety and stability for the CB20B quadruple bucket foundation platform under different work situations are discussed.
