In practice, footings may be constructed near each other which results in an interaction between foundations and leads to significant effect on bearing capacity (BC), failure mechanism, footing settlement and tilting. This paper reviews comprehensively the progress and state-of-the-art relevant to footing interference investigations and applications. This review covers experimental and theoretical (analytical, numerical and statistical) and field studies which have been performed on the footing interference effects under static and seismic loads defining the variation of efficiency factor (ζ) and its influence on the BC, settlement and tilting of supported structures. The present study reveals the role of current research situation, existing deficiencies and future outlooks on the interfering footings. From the results of past findings and using optimization and statistical algorithm, some relationships for different cases are recommended to estimate the efficiency factor and extending classical equations for practical design. It has been concluded that in general case, apart from well-known factors the footing interference effect depends on embedment depth, width and shape of footings, spacing between footings, and differential load intensity on the footings.

在实践中，立脚可以彼此靠近构造，这会导致基础之间的相互作用，并对承载力（BC），破坏机制，立脚沉降和倾斜产生重大影响。本文全面回顾了与立足点干扰研究和应用相关的进展和最新技术。这篇综述涵盖了实验和理论（分析，数值和统计）以及现场研究，这些研究是针对在静态和地震载荷下确定有效系数（ζ）及其对BC的影响，支撑结构的沉降和倾斜。本研究揭示了当前研究状况，存在的不足以及对未来基础的影响。根据以往的研究结果，并使用优化和统计算法，建议针对不同情况的一些关系来估算效率因子并扩展经典方程式，以进行实际设计。已经得出结论，在一般情况下，除众所周知的因素外，基础干涉效应还取决于嵌入深度，基础的宽度和形状，基础之间的间距以及基础上的差异负载强度。
