Abstract
The dynamical models related to development of the joint system (commonly called “Sheeting”) with horizontal or slightly inclined trend, found frequently in the weathered granitic rocks, have been considered in detail concerning the cases of the primarily horizontal topography and of the sloping ground produced after dissection. As a result it has become evident that (1) removal of the stress ascrived to the load lying over the land surface in surely one of the important factors, (2) possibility of the dynamical heterogeneity resulted from development of the timy-scaled sheeting in the weathered part of the granitic rocks in deducible from inspection of some data of the measurement referred, and (3) in consequence scruting of disposition of the sheeting is considerably useful as a indicator for classifying the strength of the basement rocks.
