群桩基础安全稳定性评判决策中各因子评判标准边界的确定是保证其模型正确构建的关键环节。由于安全监测系统无法测得这种警戒值,因此,本文采用基于ABAQUS软件的数值模拟方法,依据上部结构受力特点及使用要求来确定群桩基础安全稳定性判别决策因子的警戒值。仿真结果显示:该方法能可靠获取超大型深水群桩基础成桥后的基桩轴力不均匀性和差异沉降的最佳警戒值。
The determination of the criterion of each factor in decision-making of group pile foundation safety and stability is the key to ensure the correct construction of the model. Because the safety monitoring system can not measure this warning value, this paper adopts the numerical simulation method based on ABAQUS software to determine the warning value of the decision-making factor of the safety stability of pile group foundation according to the characteristics and requirements of the superstructure. The simulation results show that this method can obtain the best warning value of pile foundation axial force inhomogeneity and differential settlement after construction of super-large deep-water group pile foundation.
