摘要： 若能了解矩形巷道孔边的应力集中系数表达式，则对矿山水平矩形巷道的设计和支护都有很大的帮助。首先通过量纲分析，将与矩形巷道有关的参数无量纲化，然后借助复变函数这一方法，推导了应力集中系数K_t与比例系数k、s之间的函数关系以及Kt与比例系数n之间的函数关系，并且均与数值模拟结果进行了对比分析，得到了较为满意的结果。

Abstract: If stress concentration factor expression for rectangular drift opening is known, it can be of great help in the design and support of mine horizontal rectangular drift.Dimensional analysis was first made and parameters relating to rectangular drift were made dimensionless.By means of functions of complex variable, the functional relations between stress concentration coefficient K_tand ratio coefficients k, s, n were deduced and compared with numerical simulation results, which achieved satisfactory results.
