Displacement calculation method and apparatus for underground structure

The invention discloses a displacement calculation method for an underground structure and belongs to the field of earthquake resistance of underground structures. The displacement calculation method for the underground structure comprises steps of acquiring a first quick calculation formula and acquiring soil mass displacement parameters. The first quick calculation formula displays a change relationship between displacement of the underground structure and soil mass displacement parameters of the soil mass in a preset range; the soil mass displacement parameters display displacement of the soil mass; and displacement of the underground structure can be calculated according to the soil mass displacement parameters and the first quick calculation formula. Problems of low displacement calculation efficiency and accuracy due to the earthquake can be solved for the underground; and displacement calculating speed and result accuracy can be improved for the underground structure. 本公开揭示了种地下结构的位移计算方法，属于地下结构抗震领域。所述地下
