摘　　要：楠竹加筋复合锚杆是一种用于土遗址加固的新型锚定杆件,其内粘结剂由粉煤灰、石棉、环氧树脂制成。内粘结剂是一种新型纤维复合材料,通过弹性纵波波速测试、无侧限压缩试验、巴西劈裂试验得出了内粘结剂的最短养护时间、抗压强度、弹性模量、抗拉强度等物理力学指标。结果表明,按照新疆交河故城粉土崖体加固工程配比设计的内粘结剂具有良好的力学强度和较低的密度,有利于楠竹加筋复合锚杆内部应力的有效传递。Bamboo-steel cable （BSC） composite anchor is a new type of anchoring rod used to stabilize soil cliff in an ancient site. Its inner binding agent consists of fly ash and asbestos and epoxy. The inner binding agent is a new type of fiber reinforced composite material,its physical and mechanical indicators such as shortest curing time,compressive strength,modulus of elasticity and tensile strength are obtained by elastic wave velocity test,unconfined compression test and Brazilian test. The results show that the inner binding agent has a higher strength and a lower density,and is in favor of effective transfer of internal stress for BSC composite anchor according to proportioning design of ancient city silty soil cliff consolidation work in Xinjiang Jiaohe.
