flac3D 5.0 manual user's guide - section P3-50: " In all civil or mining engineering projects, there is an in-situ state of stress in the ground, before any excavation or construction is started. In FLAC3D, an attempt is made to reproduce this in-situ state by setting initial conditions. Ideally, information about the initial state comes from field measurements. But, when these are not available, the model can be run for a range of possible conditions. Although the range is potentially infinite, there are a number of constraining factors (e.g., the system must be in equilibrium, and the chosen yield criteria must not be violated anywhere). "

P3-56:  " No initial state is the “correct one”: the choice may depend on the type of geological process that is believed to have occurred in the field."

计算初始地应力分布，与初始设置条件是有关系的。
