| 英文摘要 | With the advantages of both granular piles and rigid piles, pervious concrete piles (PCPs) are especially suitable for improving ground bearing capacity. To study the dynamic performance characteristics of PCP composite foundation under earthquake loads, the acceleration response of subgrade and the development and dissipation of excess pore water pressure in composite foundation during the earthquake were numerically calculated. The dynamic performances of PCP were compared with those of gravel pile and low-grade concrete pile. The surface acceleration amplification coefficient of PCP composite foundation is obviously smaller than two other composite foundations. Meanwhile, its predominant period is only half that of the gravel pile and low-grade concrete pile composite foundation, which demonstrates that PCP composite foundation is more effective for avoiding the mechanical resonance of the upper building. Besides the significant damping effect, it also has obvious pressure-reduction effect. The excess pore water pressure induced by an earthquake dissipates quickly because of the high permeability of PCPs, and foundation liquefaction is effectively inhibited. Consequently, the draining-damping coupling effect of PCPs can improve deformation compatibility of soil during the earthquake. (C) 2017 American Society of Civil Engineers. |
