Abstract There are two types of theorems in large deformation analysis of deep soft rock engineering，i.e. polar decomposition theorem and solar decomposition theorem，which the deformation gradient F is decomposed into addition of deformation and rotation by a co-moving coordinate system method. However，there is no finite element methou(FEM) software including solar decomposition theorem up to now，except the finite element software on large deformation analysis for soft rock engineering at great depth，briefly called Large Deformation Engineering Analyses Software(LDEAS) including a solar decomposition increment module. The finite element equations based on solar decomposition theorem were given；according to the functional expression between geostress and depth proposed by Hoek-Brown，the solar decomposition increment module was adopted to analyze the large deformation of a tunnel excavated at six different sets of designed depths to find the relation between deformation and depth. The results indicate that：the deformation of surrounding rock increases with increasing depth；the maximum value of relative displacement between floor and roof is much larger than that of the sidewall shrinkage；and each of them has a good linear relationship with depth；the increasing rate of relative displacement between floor and roof is larger than that of the sidewall shrinkage.

Key words： rock mechanics deep soft rock engineering solar decomposition large deformation
