从实际工程出发,对桩土水平相互作用进行简化抽象为平面分析问题,采用FLAC~(3D)数值计算方法,通过不同工况的加载,对比主动桩和被动桩计算结果,对单桩与其周边土相互做用进行研究。通过数值计算及分析单桩桩-土间相互作用机理,得到一些有用的表格数据及分析方法,为进一步桩土相互作用进行参数分析,以及深入研究群桩与土相互作用、桩基与土相互作用提供理论依据,这对预防滑坡、软土滑动等对桩基础以及构筑物的破坏有重要的意义。
Based on the practical engineering, simplified abstraction of horizontal interaction between pile and soil is the problem of plane analysis. The FLAC 3D numerical calculation method is adopted to compare the calculation results of active pile and passive pile by different working conditions. Soil mutual research. Through numerical calculation and analysis of single-pile-soil interaction mechanism, some useful tabular data and analysis methods are obtained to conduct parameter analysis for further pile-soil interaction and further study on the interaction between pile groups and soil. Provide a theoretical basis for the role, which is important to prevent landslides, soft soil sliding and other damage to the pile foundation and structures.
