为了对金陵大报恩寺地宫遗址进行科学保护,首先通过ANSYS有限元模拟对地宫遗址的现状结构性能进行分析,找出其在不同工况下存在的安全隐患;然后根据保护原则及计算分析结果提出仅增设护壁、增设护壁及锚杆的两种保护技术方案,采用ANSYS有限元模拟计算对两种保护技术方案在四种工况下的结构性能进行比较分析,最后提出了适用于地宫遗址的保护方案,建议采用增设不锈钢的护壁及水平、竖向锚杆,并给出了不锈钢护壁及锚杆相应的参数值。
In order to provide a scientific basis for preserving the Underground Palace in Jinling Dabaoen Temple, actual structural information of the Underground Palace was analyzed using engineering simulation software: ANSYS. Structural safety problems under various combinations of construction loads were noted. Then two different conservation designs involving the adding of sleeves and adding of sleeves and anchor rods were evaluated based on the conservation rules and the results of theoretical analysis. The structural performances of the two designs under four load combinations were analyzed comparatively by ANSYS. Finally, a conservation design plan for the under- ground palace in Jinling Dabaoen Temple was decided upon. The plan suggests adding both sleeves and anchor rods. The engineering parameters of the sleeves and anchor rods are also presented.
