摘要
始建于宋初的梵天寺经幢在上千年自然应力的作用下,出现了大面积的构件破坏和缺损,造成重心偏移,严重影响了经幢的整体稳定。经现场调查分析已知,经幢所用岩体节理面比较发育,结构面及其充填物的变形是岩体变形、开裂的主要原因。本文通过对南北两经幢进行数值模拟,并对各层岩石受力情况进行计算分析,得出经幢岩石构件受力分布情况,为经幢整体结构加固及保护提供科学依据。
The sutra pillars in Hangzhou Brahma Temple,built in the early years of Song Dynasty,have suffered large-scale destruction and some parts are missing under natural decay of a thousand years,resulting in center of gravity shifting,seriously affecting their overall stability.The field investigation and analysis showed that the rock joints fairly developed and deformation of rock structure and fillings are the main reasons of rock deformation and cracking.Based on numerical modeling of both the north and south pillars,and calculation of forces on layers of rock,we analyzed the force distribution of the rock members,to provide a scientific basis for consolidation and preservation of their overall structure.
