邻水建筑物地基的稳定性受力分析和建模

Stability Analysis and Modeling of Building Foundation Adjacent to Water

本文针对邻水地区地基不牢固的现状,应用牛顿第一定律、休止角、自组织临界性等相关知识,将复杂地基拆分为一些简单的地基拼接。对长方体、棱台、圆台等不同几何形状的地基体进行受力分析,建立波浪和潮汐作用下的数学力学模型。综合多维度因素,在有风雨情形下,分析三维几何地基模型的稳定性,得到水沙比与含水量的最优值。最后,进行误差分析、灵敏度分析和稳定性分析,得出科学稳定的邻水建筑地基模型。

In this paper,the complex foundation was divided into some simple foundation stitching based on New⁃ton's first law,angle of repose,self-organizing criticality and other related knowledge,according to the current situa⁃tion of the unsound foundation in the area adjacent to water.The mathematical mechanics model of wave and tide was established by analyzing the forces on the ground matrix with different geometrical shapes,such as cuboid,prismatic and circular platform.In the case of wind and rain,the stability of three-dimensional geometric foundation model was analyzed by integrating multi-dimensional factors,the optimal values of water-sand ratio and water content were ob⁃tained.Error analysis,sensitivity analysis and stability analysis were carried out,and the scientific stable foundation model of building adjacent to water was obtained.
