运用室内物理模型试验和原位试验，对基于水硬石灰与石英砂浆液的木锚杆锚固系统在夯土介质中进行了拉拔测试与杆体-浆体界面应变监测，研究了该锚固系统的锚固性能与破坏模式、杆体-浆体界面剪应变分布与传递特征。试验结果表明,该锚固系统50 cm锚固长度可以提供30~45 kN(室内)与16.2~19 kN(现场)的极限锚固力；锚固系统具有较强的延性；在加载进程中杆体-浆体界面的应力分布与传递特征具有单峰值或双峰值分布、界面应力向锚固末端传递、压应力出现在锚固段中末端等特征，表现出复杂的受力特性。研究结果表明，该锚固系统在结构形式和力学性能上适合于夯筑土遗址加固，并与遗址体具有较好的兼容性。

physical model and field experiments which consists of pullout test and strain monitoring on bolt-grout interface were conducted on wood bolts fully grouted by natural hydraulic lime and quartz sand slurry in rammed earth to study anchor capacity，failure mode，shear stress distribution and transfer along the bolt-grout interface .were studied on its Experimental results shows that ultimate anchor force in laboratory (30 kN~45 kN) is larger than that in field (16.2kN~19kN). Anchor system has strong ductility. In the process of loading, single-peak or double-peak stress distributes along bolt-grout interface and interfacial stress transfers toward anchor end, meanwhile, compressive stress mainly emerges at middle-end of anchor segment. With considerably physical and mechanical compatibility to rammed earth, the anchor system is suitable to conserve rammed earth heritages.
