THE STUDY OF CRUSHED STONE CRAWL MECHANISM ON HILLSLOPES OF WEATHERED SURFACE

The Ccrawl movement of crushed stone on hillslopes of weathered surface is a natural and dependent varied environmental slow geological deformation.This paper described the movement mechanism of this natural phenomenon and its movementform,besed on the study of surveying data and observation from a seious of in - site trialsurveying methods.Thisalso posed the preliminaly assumptions and trials of the possible mechanical and mathematical models for this natural phenomenon.
