| Abstract: | This paper analyzes the influence of pile spacing, pile diameter and pier cross-section on the stiffness of bridge foundation through the calculation of the longitudinal stiffness at pier-top. It also discusses how to select the reasonable pier stiffness and foundation stiffness under the condition of the same longitudinal stiffness, so as to guarantee the structural design to be rational and economical. |
