摘    要: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. 基于全长粘结式锚杆的Mindlin解,对其抗拔力进行了理论分析,推导出抗拔承载力计算公 式,通过现场试验,对理论分析结果进行了验证,并就影响锚杆抗拔承载力的因素及其破坏 模式进行探讨. 试验结果表明,土工长丝锚杆可以满足土建筑遗址墙体加固的要求;通过加 肋改变锚杆表面状态对锚固力的提高非常显著.

关 键 词:土建筑遗址  土工长丝锚杆  承载力  破坏模式

Abstract:Combined the consolidated project of Gaochang Soil Ruins in Xinjiang Province, and directed toward the new type of geo-filament bolt, the theoretical analysis of bearing capacity is done based on the Mindlin theory of fully grouted bolt. The site test results are compared with the theory. In addition, the surface state and the failure mode are researched. The experimental study reveals that the geo-filament bolt can satisfy the consolidation requires of the earthen architecture site and the change of the bolt surface through adding ribs affects obviously the anchor force. The geo-filament bolt is proved to be an excellent material for the walls reinforcement of earthen architecture sites.
Keywords:earthen architecture site  Geo-filament bolt  bearing capacity  failure mode
