Centrifugal Experimental Study On Seismic Response Of Bridge Pile Group Foundation In Saturated Sand Field Overlain By Water, Zhi-Xiao Yan, Yu-Run Li, Dong-Sheng Wang, Yong-Zhi Wang
Rock and Soil Mechanics
In order to explore the dynamic interaction of the soil−pile group foundation−bridge structure system in saturated sand field overlain by water, a physical similarity model of the vertical (inclined) pile group foundation−bridge structure was designed and manufactured. Centrifuge shaking table tests with seismic wave inputs of different ground motion intensities and characteristics were conducted. The dynamic characteristic indices of pile group foundation−bridge structure were analyzed, and the development of excess pore water pressure in the saturated sand foundation overlain by water and the dynamic response of pile−soil interaction were also investigated. The results indicated that the presence of overlying water …

Model Test And Finite Beam Element Solution Of Cyclic Lateral Characteristics Of Piles In Sloping Ground, Wen-Zhe Peng, Ming-Hua Zhao, Chao-Wei Yang, Heng Zhao
Rock and Soil Mechanics
To reveal the cyclic lateral characteristics of piles in sloping ground under the combined influence of slope effect and cyclic weakening effect, one-way cyclic lateral loading tests with different cycle numbers, load amplitudes and slope angles were carried out, and corresponding lateral static loading tests were conducted as a comparison. The variation trends of pile head deflection, bending moment and subgrade reaction were revealed. Then, the element stiffness matrix was improved by considering the second-order effect and pile-soil interaction to develop the finite beam element solution. Finally, the theoretical predicted curves were compared with measured curves and results calculated by …
