Abstract: According to the characteristics of highway engineering,as to the eigenvalue of ground bearing capacity in the construction department, the corrections concerning width, relative allowable deformation and stiffness are carried out. The design value of road base bearing capacity matching the characteristics of road base in loess area are put forward. The checking method of road base bearing capacity in loess area is determined correspondingly.

Key words: loess area, highway, ground design, ground bearing capacity, sedimentation deformation, checking method
