摘要:
本文通过室内模型试验,研究扩底群桩在水平荷载作用下桩土相互作用的变形机理。通过埋设的传感器测得桩间土压力、桩侧土压力等数据,换算桩身应力、弯矩,分析桩土相互作用变化规律;结合有限元软件建立多种扩底桩计算模型,研究桩长对桩土相互作用的影响规律,本文的研究结果对扩底桩基础的理论发展及工程推广应用提供有力的科学依据。
Abstract:
According to indoor model test, we research the deformation mechanism of the interaction of soils of expanding belled pile group under the horizontal load. The embedded soil sensor measures the soil pressure between pile side to convert the pile body stress and bending moment, and analyzes the variation law of pile-soil interaction. Combined with finite element software,the calculation model of various piles is established to study the influence law of pile length and pile-soil interaction. The research results of this paper provide a strong scientific basis for the theoretical development of the expanding belled pile foundation and engineering application.
