【摘要】 工程桩周围经常会存在不平衡的堆载现象,大面积填土引起的荷载对相邻建筑物桩基的影响主要集中在三个关键问题:负摩阻力问题、被动桩问题和土体的蠕变效应与时变效应问题.本文采用有限元软件ABAQUS对新吹填区不平衡堆载的桩土模型进行有限元计算,从堆载高度、距离和宽度三个方面对不平衡堆载的单桩水平特性的影响进行了比较分析,可为实际工程提供一定的参考.更多还原

【Abstract】 Imbalanced surcharge loads are often found exist around engineering piles. The impacts of load caused by large area backfilling earth on the pile foundation of adjacent buildings are negative friction problems, passive pile problems, transient effects and soil creep effect. This paper calculates the pile-soil model of imbalanced surcharge loads at new reclamation area by using finite element software ABAQUS. The impact of imbalanced surcharge loads on single piles is studied in terms of the height, distance, and width of loading. This research is of help for practical projects.更多还原
