摘要: PHC管桩打入过程中对桩周土的物理力学特性有着较大的影响,依托山东黄河冲积平原区某电厂工程项目,对PHC管桩的沉桩过程运用FLAC 3D进行数值模拟分析研究,建立了挤土效应下桩周厚液化土层在水平振动下的动力应变模型,分析了打桩过程中桩周土的液化发展特性。

Abstract: The installation of the High Strength Concrete (PHC) pipe piles has a significant impact on the physical and mechanical properties of the surrounding soils. The installation of the PHC pipe pile is numerically simulated based on an electricity power plant project in Yellow River Alluvial Delta of Shandong Province. The dynamic strain model in the surrounding soil under the horizontal excitations is established and the development of the liquefaction during the pile installation is presented.
