摘　　要：在分析国内外初始地应力场研究现状的基础上,研究了考虑地形及构造应力影响下,基于3D-FSM间接边界元法的初始地应力场反演分析法,并开发了相应的数值计算系统。利用工程实例说明了分析步骤,并验证了该方法的适应性及精度。Based on the analyzing the research status of the initial ground stresses at home and abroad, the initial ground stresses back analysis method with usable program based on the 3D-FSM IBEM considering the influence of te, rrain and tectonic stress has been studied. And the corresponding numerical analysis subsystem has also been developed. The analysis procedure is expatiated by using an actual project example; meanwhile, it verifies the applicability and calculating precision of the method.
