Discussion on Engineering Problems of Iron-shaped Rock Pillar of the Niuchang Ancient Caverns in Longyou Grottoes
摘要
Abstract
The Niuchang Ancient Caverns in Longyou belong to the Longyou Grottoes,a national key cultural relic protection unit.The ancient caverns contain a series of highlights of ancient engineering structures.In order to study the mechanical characteristics of iron-shaped rock pillar,with the help of Geomagic software,the three-dimensional models of ancient caverns with iron-shaped rock pillar and rectangular equal-section rock pillar were established respectively,and then the finite element grid division is performed with Abaqus software.Finally,the article used FLAC 3D software to analyze its displacement and stress under own weight.The results show that:compared with the rectangular rock pillar,the iron-shaped rock pillar have different degrees of reduction in the settlement and stress of the Niuchang Ancient Caverns,and the original iron-shaped rock pillar is more stable and scientific.This proves that the iron-shaped rock pillar set by the ancients are more conducive to the long-term stability of the ancient caverns than ordinary rectangular rock pillar.关键词
