摘 要：In this paper,one unique cloud-shaped nock pillar is discovered in an ancient quarry in Zhejiang Province,Textual research indicates that this ancient quarry was initially exploited La Liang Dynasty(502-557 BC}.Geological conditions of the ancient quarry arc elaborated in this *** investigation results indicate that this rock pillar was left during *** reconstruction through the data acquired by 3D laser scanning presents that ii has a complex ***-Dimensional finite difference stimulation using Mohr-Coulomb parameters acquired from back analysis has been conducted to analyze its stress distribution and *** results suggest a maximum stress of1,7 MPa in this pillar,the stress reduces from bottom to top,and from one side to the opposite side of the pillar,and finally the stress exhibits a similar *** displacement in B side reduces from bottom to top,then increases reversely.
