摘　　要：利用线夹杂的工程计算模型以及无限平面中单夹杂的基本解 ,分析了无限平面中两根径向弹性线夹杂的相互干扰问题·　并将线夹杂和线夹杂相互作用的问题归结为解一组柯西型奇异积分的积分方程组 。Using the engineering model of elastic line inclusion and the basic solutions of a single inclusion, the interaction problem between line inclusions in an elastic solid was investigated. A set of standard Cauchy-type singular equations of the problem was presented. The stress intensity factors at points of inclusions and the interface stresses of two sides of the inclusion were calculated. Several numerical examples were given. The results could be regarded as a reference to engineering.
