Abstract:
Based on the three-dimensional stress state and some assumptions of the tapered bucket foundation, we used the limit equilibrium method to obtain the calculation formula of horizontal bearing capacity of tapered bucket foundation, and compared the results with the model test results, and thus validated the reliability of the formula. Through varying different parameters, we analyzed the influence of the obliquity of bucket wall, proportionality coefficient of soil resistance, top diameter of bucket foundation, height-diameter ratio of bucket foundation, and height of acting point on the value of horizontal bearing capacity of tapered bucket foundation. It was found that the horizontal bearing capacity increased rapidly as the obliquity of bucket wall increased. The results of this research are helpful to the optimization design of traditional bucket foundation.
