| Abstract: | To compare the bearing capacities of the traditional spudcan and the bucket spudcan,the effects of different-type spudcans on the rigidity of pile legs and the entire bearing capacity were analyzed in detail.Through the loading method of Swipe and constant displacement,this paper plots the spatial failure envelopes of the vertical-horizontal load,vertical-moment load,vertical-horizontal-moment load of the bucket spudcan and traditional spudcan under the mode of composite loading,as well as the spatial failu... |
