摘　　要：本文在空间轴称问题中,导出了圆域分布垂直力源作用下的地面位移表达式,并进行了数值计算和震例分析,研究了不同参数的垂直力源与地面位移的关系。In the case of radial symmetry, the expressions of the surface displacement due to the vertical force source uniformly distributed over the area of a circil are derivated. The results of numerical calculation are discussed and applied to the analysis of the 1976 Tangshan earthquake. This paper also studies the relations between the vertical force source and surface displacement fields with different parameters.
