Application of three-dimensional laser scanning technology in historic stone’s numerical simulation
SHI Jun-li
Abstract：In order to accurately simulate the structural stability of the stone relics,with Yungang 11 th Grotto as object,it used three-dimensional laser scanner quickly to accurately obtain caves surface array data,and ANASYS to make internal network structure split and finally imported Flac3d on Grotto whole seismic re-sponse simulation.The result showed that:the overall direction of displacement of rock caves of Yungang the 11 th Grotto was a downward tilt with good stability over time and gradually downward portion with stress concentration.It was predicted that without taking protective measures for the bottom of the recessed portion weathering,the bottom of the cave would lead to instability in 100 years due to stress concentration destruc-tion.Based on this corresponding reinforcement measures were proposed.
