摘要

摘要: 土建筑遗址是古人留给我们的珍贵文化遗产,其破坏已十分严重。目前保护主要从化学和物理加固两方面考虑。与化学保护相比较,结构稳定性加固更是刻不容缓。结合新疆高昌故城土建筑遗址保护工程,将土工长丝这种新型锚杆应用于墙体加固,简要介绍了杆件材料的特点、性能和施工工艺,并对土坯墙体中的锚杆进行拉拔试验,从不同的影响因素上对锚杆承载力进行对比分析。试验结果表明,锚杆表面状态对锚固力的影响较大;锚杆的长度不宜太大,以0.8~1.5m为宜。对小型土建筑遗址墙体加固而言,土工长丝锚杆是一类优良的材料,具有技术先进、工艺新颖、施工方便、对文物本体破坏较小等特点,有广泛推广应用的价值。

Abstract: The earthen architecture site is a rare cultural heritage which is destroyed seriously. The protections of the earthen architecture site include two aspects which are chemistry and physics protection at present. Compared with chemical protection, the structure stability is more important. Combined the protected project of Gaochang Soil Ruins in Xinjiang, the new type anchor of geo-filament anchor is used, whose construction technology is introduced; in addition, the numerical comparative tests in typical soil medium were implemented and compared the bearing capacity of anchor from the different affections. According the test results, the surface state affects the anchor force obviously; the length of archor is feasible from 018～115m. Geo-filament archor is proved to be an excellent material which is used in the walls reinforcement of earthen architecture sites, and it has many typical characters which are advanced technology, novel techniques and convenient construction. Because of that, the new research will play an important part in guiding us to protect the earthen architecture sites.
