| 摘 要： | 本文实施了金属和玻璃纤维锚头的极限抗拔承载力的模型试验。结果表明,金属螺母长度达到10cm时,玻璃纤维增强聚合物锚杆锚头达到其极限抗拔承载力。该锚杆破坏形式为扒皮破坏,表层平均脱落厚度在2.4~2.7mm之间。起抵抗剪切破坏作用的主要是基体树脂及其附近的少数玻璃纤维。螺母长度为8cm的玻璃纤维增强聚合物锚头极限抗拔承载力,大约等同于金属螺母长度范围为6~7cm的锚头抗拔承载力,产生的位移值约是后者的2倍。

| Abstract: | A series of model tests were conducted on the ultimate tensile capacity of glass fiber reinforced polymer anchors using the mental screw nut and the glass fiber anchor head. The results show that when the mental screw nut is longer than 10cm, the ultimate capacity of GFRP anchor head will be achieved. The failure model of the GFRP anchor is the damage of the surface, and the average failure thickness of the failure surface is about 2.4~2.7mm. The most resistance to shear failure comes from the matrix resin and small parts of nearby glass fiber. The ultimate tensile capacity of GFRP anchors with an 8cm length of glass fiber head is approximately equal to that of the metal nuts with a length of 6 to 7 cm. However,the displacement is about 2 times the latter. |
