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.

ANCHOR THEORY AND EXPERIMENTAL STUDY OF GEO-FILAMENT BOLT

Combined the consolidated project of Gaochang Soil Ruinsin Xinjiang Province, and directed toward the new type of geo-filamentbolt, the theoretical analysis of bearing capacity is done based on the Mindlintheory of fully grouted bolt. The site test results arecompared with the theory. In addition, the surface state and the failuremode are researched. The experimental study reveals that the geo-filament boltcan satisfy the consolidation requires of the earthen architecture site andthe change of the bolt surface through adding ribsaffects obviously the anchor force. The geo-filament bolt is proved to be an excellent materialfor the walls reinforcement of earthen architecture sites.
