【摘要】 "5.12汶川特大地震"对安岳石窟所属的孔雀洞经目塔产生了较大的影响和破坏。本次勘察修缮设计目标是修复经目塔震后的直接残损,对其结构进行必要的加固,减缓风化对塔体的影响,由于破坏的突然性及抢救工作的迫切性要求,从勘察到设计仅仅1个多月时间,勘察设计方在工作之初便决定引入三维激光扫描技术,并在评估及设计过程使用计算机模拟复原技术,力求准确翔实的得出经目塔震后的评估结论,及为震落构件找到准确的原有位置。作为最终修缮设计的依据。并通过结构计算,最终确定经目塔的修缮方案。本次勘察设计过程中引入的三维激光扫描技术及计算机模拟技术在石质文物勘察设计中均具有突破性进展,为今后石质文物的科技保护进行了切实有效的探索。更多还原

【Abstract】 The 5.12 Wenchuan Earthquake caused damage and destruction to the Canon tower of the Peacock Cavity in the Anyue Grottoe.The aim of the project is to repair damage caused by the earthquake,to restore the frame, to reinforce the structure,and to decrease the effects of natural aging.Due to the unexpected destruction and the resulting rescue demands,this mapping and preservation project was completed in only one month.The three-dimension LASER scan technology was introduced from the beginning.Thus,through application of computer simulation technology,the computer-simulated rebuilt tower model can accurately assess the destruction of the Canon Tower and determine the original location of each damaged component.Together with structural calculation,these data provided a reference for final decision regarding the preservation plan.The application of three-dimension Laser Scanning and computer simulation was successful and stands as a milestone for the investigation and preservation design for stone relics.It represents a useful technique for scientific heritage conservation.更多还原
