摘要
本文提出了一种新的考虑材料参数随机分布的边界元计算方法．推导出材料参数按空间呈高斯型正态分布时边界元基本计算公式，利用这些公式可以计算出每个单元的位移和面力的均值与方差，从而求出结构的可靠度．
In this paper, a computational method of 2-D probability boundary element is developed. With the combination of probatility boundary element, the PBEM formulation is derived. The average value and the vaviance of the structure can be calcuted. From this formualtion, the method of this paper developped can be usded in the reliability of the structure.
