应县木塔结构监测与试验分析研究综述

A summary on the research and analysis of testing and monitoring the Yingxian County Timber Pagoda structure

应县木塔历史悠久,结构复杂,其主要结构构件及构造做法基本上保留了原建时期的面貌,是研究我国早期古代建筑技术及大木制度的重要实物遗存,具有独特的艺术价值和极高的科学价值和成就。然而,由于年久失修,再加上民国时期的错误修缮和战争年代的炮弹袭击以及后来多次地震的损伤累积,当前,应县木塔二层明层结构倾斜变形严重,底部三层结构病害缠身,结构亟须修缮加固。近80年来,国内数十家单位参与应县木塔保护和研究工作,取得一些成果,为制定应县木塔保护方案提供了理论依据和基础数据。本文围绕应县木塔结构试验、结构计算及结构监测等几个方面的工作,梳理和归纳了应县木塔结构监测与试验分析的研究现状,并提出现存问题和建议,供相关研究和技术人员参考。

The Yingxian Timber Pagoda＇ s most structural components are original, that is the most important cultural heritage for the study of Chi- nese architectural technology and rules for its long history and the complex construction. However, at present, the Timber Pagoda needs strengthening by reparative method due to out of repair for years. Worst of all, the second story of the Timber Pagoda leant severely due earthquakes and wars. In the past 80 yem＇s, more than tens domestic work units have been invited to participate in the study and conservation of the Timber Pagoda. The results of their research can be applied to design the conservation proposal. This paper summarizes and analyzes the research done on testing and monitoring the Timber Pagoda＇ s structure and put forward questions and suggestions for the relative researchers and engineers.
