用MCA方法对地基不均匀沉降引发的墙体裂缝的仿真研究

Simulation on the Cracks in the Wall Casued by Foundation's Uneven Settlement with MCA Method

用可移动元胞自动机数值模拟(MCA)方法,对三种常见的地基不均匀沉降形式进行二维数值模拟,得出了地基不均匀沉降引起的墙体裂缝形式,讨论裂缝产生的机理,得到的裂缝形式和载荷位移曲线与相关文献吻合.

The three common forms of the uneven settlement of the foundation is numerically simulated（2D） using the numerical simulation method by MCA. Some forms of the cracks caused by the uneven settlement of the foundation are obtained, and mechanism resulting in the cracks is discussed. The cracks form and the load displacement curve acquired are conicident with the relevant literature.
