Moving ships and other objects drifting on water often impact a bridge's pile foundation. The mechanical model of the piles-bridge
structure under horizontal forcing was established, and a time-domain approach based on Finite-difference Method was developed
for analyzing the dynamic response of the piles-bridge structure. For a single pile, good agreement between two computed results
validated the present approach. The slenderness ratio of the pile, the pile-soil stiffness ratio and the type of the structure
influence the dynamic response of the piles-bridge structure. The computed results showed that the stiffness of the structure
determines the dynamic response of the piles-bridge structure under horizontal forcing.

Correlation of liquefaction resistance with shear wave velocity based on laboratory study using bender element 总被引：1，自引：0，他引：1
INTRODUCTION Evaluation of soil liquefaction resistance is an important aspect of geotechnical engineering practice, and several types of evaluating procedures have evolved over the last three decades. The well known “simplified procedure” originated by Seed and Idriss (1971) can be used to evaluate liquefaction resistance based on standard penetration test (SPT) blow counts. Over the years, the simplified procedure has been modified and updated with additional data, and has become th… 相似文献

INTRODUCTION Recently, more and more investigations have been conducted on multilayer piezoelectric media. Kharouf and Heyliger (1994) and Heyliger and Ra- mirez (2000) dealt with the free vibration problems of laminated piezoelectric cylinders and discs, respec- tively. Chen (2000) considered the free vibration of (multilayer) nonhomogeneous piezoceramic hollow spheres by employing a separation formulation for displacements. Chen (2001) developed a state-space method for free vibration … 相似文献

介绍某多层中间覆盖层填埋场边坡滑移过程的现场监测结果,包括渗滤液水位、表面水平位移和深层侧向位移.基于监测数据,开展稳定性分析,验证顶层降水、分层降水及近边坡区域降水的稳定控制效果.结果表明:最大滑移面积达到34 760m~2,第10平台的平均表面水平位移量为1.77m;近边坡区域的堆载是其失稳的主要原因;距堆载区越近,滑移程度越大,水位上升更显著;受中间覆盖层的影响,该类型填埋场的主要失稳模式是堆体内部的局部滑动;近边坡区域降水对其稳定控制效果明显. 相似文献

Axisymmetric fundamental solutions that are applied in the consolidation calculations of a finitecaly clay layer with impeded
boundaries were derived. Laplace and Hankel integral transforms were utilized with respect to time and radial coordinates,
respectively in the analysis. The derivation of fundamental solutions considers two boundary-value problems involving unit
point loading and ring loading in the vertical. The solutions are extended to circular distributed and strip distributed normal
load. The computation and analysis of settlements, vertical total stress and excess pore pressure in the consolidation layer
subject to circular loading are presented.
