摘要
以相似理论为基础,通过建立基坑的地质结构模型,采用物理模拟研究中的底摩擦试验方法,研究了基坑在时间和空间上的变形特征,试验结果表明:基坑变形是一个持续的变形过程,在有附加荷载的情况下更快更明显,并且由变形所产生的裂缝的位置与附加荷载作用边界及其大小都有关系。
On the basis of similarity theory, through establishing foundation geology structure model, applying bottom friction testing method used in physical simulation research, the paper studies the time and space deformation characteristics of foundation. Experimental results show that： foundation deformation is a continuous deformation process; foundation deformation will be faster and more obvious under additional load; deformation cracking Iacation is related with additional load boundary.
