The traditional geotechnical engineering deformation repair method takes a long time, has low precision and poor effect. In order to solve this problem, a method of geotechnical engineering deformation damage repair based on elastic–plastic mechanics is proposed. Firstly, the balance equation, constitutive equation and evolution equation of deformation and damage in geotechnical engineering are established; then the deformation and failure process of geotechnical engineering is deduced, and the failure value of rock mass is calculated; finally, the deformation and damage repair in geotechnical engineering is completed by using elastic–plastic mechanics method. The experimental results show that, compared with other methods, the damage value of this method is consistent with the actual damage value, and the repair accuracy is high. The calculation time is in the range of 2–4 s, and the repair efficiency is high. Moreover, this method can achieve the ideal effect of geotechnical engineering deformation repair.
