高桩码头在淤积作用下的承载力分析

根据检测报告,台州发电厂高桩码头桩基、上部构件存在不同程度损坏情况。由于码头处于河道扩大段,淤积严重,为探讨岸坡淤积对码头安全性影响,本文运用ABAQUS软件,以M-C材料来模拟土体的弹塑性性质,采用梁单元模拟桩基,横梁结构,根据实际岸坡线,建立桩-土相互作用二维有限元模型,分析了淤积自重作用下对桩基产生的内力与变形,计算结果表明在淤积自重作用下,码头有向海侧移动趋势,后排桩基下部受力较大,但桩基承载力富余量充足,码头受力处于安全状态。     

Determination of optimal probabilistic seismic demand models for pile-supported wharves

One of the basic components of the Performance-Based Earthquake Engineering (PBEE) framework of Pacific Earthquake Engineering Research (PEER) Center is the probabilistic seismic demand model (PSDM). PSDM is based upon a representative relation between ground motion intensity measures (IMs) and engineering demand parameters (EDPs). This research aims to develop an optimal PSDM for typical pile-supported wharf structures in western US ports by using probabilistic seismic demand analysis (PSDA). In this study, 4 bins with 20 non-near-field ground motions and 7 typical pile-supported wharf structures are used to determine an optimal PSDM by PSDA. The model geometry used in this study has a hybrid configuration incorporating many common field conditions. The optimal PSDM should be practical, sufficient, effective and efficient – all tested through several IM–EDP pairs derived by PSDA. The ground motion IMs used in this study include characteristics such as spectral quantities, duration, energy-related quantities and frequency content. Different EDPs are considered for local, intermediate and global response quantities. The considered optimal PSDM comprises a spectral IM, such as spectral acceleration and one of several EDPs. The EDPs of moment curvature ductility factor, displacement ductility factor and horizontal displacement of embankment and differential settlement between deck and behind land are considered for local, intermediate and global response quantities, respectively. Optimal PSDMs are used within PEER–PBEE framework, where they are coupled with both ground motion intensity and structural element fragility models to yield probabilities of exceeding structural performance levels under certain seismic hazard.
