EXPLORATION OF e-lgp METHOD TAKING ACCOUNT OF RHEOLOGY AND LATERAL DEFORMATION

Finite element method can consider not only soil lateral deformation but also rheology during settlement calculation of highway, but the course is more numerous and not easily mastered by common engineering technicians.With a lot of nonlinear finite element method calculations, one settlement general modification formula is brought out, which may cause the e-lgp method to consider lateral deformation, then, based on the fact of secondary compression related to loadings, the absolute time coordinate sy stem is suggested for secondary compression calculation, by the traditional secondary compression calculation formula is rectified.Thus, during the 1-D settlement calculation of highway, the thing that in consideration of rheology and lateral deformation can become reality when combined the above two sides.This thought can cause more accurate results and can be lightly mastered, so it has definite using value in practical engineering.
