摘要
提出了复杂初始地应力场的力学模型。在该模型中，地应力不必符合某种特定的分布，通过求解构造应力在边界上的节点力，可以确定这种地应力。讨论了在线弹性介质中，通过有限元计算求解这种地应力的方法、过程，并给出算例。
A mechanical model for complex initial geostress field is put forward.Different from the geostress adopted often,the initial geostress,in this model,does not necessarily follow a certain kind of distribution law.And it can be back analyzed by determining boundary node forces due to tectonic stress.The method and process to back analyze the above initial geostress in linear elasticity material with finite element method is discussed,followed by an example.
