摘　　要：地基基础质量会直接影响上部结构的安全。现有的相关研究中,人们更关注地基的属性,却往往忽视了基础这一重要构件的作用,对基础质量的相关研究并不多见。本文结合一个条形基础质量缺陷的工程实例,采用有限元方法,对缺陷基础轴压荷载作用下的力学性能进行数值分析。并对工程检测中常见的带有质量缺陷的条形基础进行模拟,明确了各种质量缺陷对条形基础属性的影响,并提出了一种针对条形基础缺陷的加固方案。The safety of structure was related to the quality of the However, the relative literatures mainly focused on the foundation quality member, the function of strip basis was usually ignored. In this paper, t basis, found in practice and under axial load were analyzed, by the finite foundation and basis directly of structures. As an important he behaviors of detective strip element method. The influences of common defects on the behaviors of strip basis, under axial load, were further studied by numerical analysis. A strengthening scheme was provided finally.
