| 摘 要： | 基于土力学理论,结合数值分析的方法建立长江漫滩典型地质条件下地基土层及其表面的建筑荷载模型,采用ANSYS计算软件对其进行模拟分析,探讨建筑物间距、建筑物规模对建筑物差异沉降的影响,分析相邻建筑物作用下的沉降影响范围变化规律。结果表明,建筑物间距、建筑物规模对建筑物差异沉降会产生不同的影响,相邻建筑物作用下的水平和深度影响范围也有不同的变化规律。

| Abstract: | Based on the theory of soil mechanics and numerical analysis method ,a foundation soil and building load model of Yangtze River floodplain is established ,and analyzed through ANSYS calculation software on differential settlement of buildings caused by spacing of buildings and building scale . The results show the differential settlement caused by spacing of building and building scale is different ,as well as the variation of the level and depth of influence scope of adjacent buildings . |
