台藏塔结构病害分析与维修加固措施研究

Analysis and Reinforcement of Structural Disease of Taizang Tower

经实地考察研究发现台藏塔遗址由于自然因素和人为因素破坏严重,存在多种形式的结构病害,且同一形式的病害对遗址的整体稳定性的影响程度不同。台藏塔维修加固过程中根据病害对整体稳定性的影响程度采取了三种砌筑技术、三种锚杆锚固技术和钢楦及钢架支撑等技术。工程实践表明,这些工程措施取得了理想的维修加固效果;也为西北干旱地区土遗址的维修加固提供了一些思路和借鉴。

After on-the-spot investigation and research,it is found that the Taizang Tower is destroyed seriously because of the natural factor and the human factor.Many kinds of diseases,and disease in identical form is different to integral stability of the ruin.Some technologies,such as three kinds of masonry,three kinds of anchored bolt,steel shoetree and steel frame support ect,had been used in the process of reinforcement of the Taizang Tower due to the influence of different kinds of diseases.By the examination of engineering practices,ideal result has been obtained after applying these protective techniques;The experience may be provide some methods to the reinforcement of earthen sites in the northwestern China.
