GFRP锚杆应变分布的数值模拟

GFRP锚杆具有抗拉强度高、抗腐蚀能力强等特点,但由于其抗剪强度较低,且具有明显的脆断现象,因此未被广泛应用于实际工程,但在临时支护工程中应用广泛,本文通过FLAC3D模拟计算在拉拔荷载作用下GFRP锚杆杆体表面的应变分布,研究GFRP锚杆在某岩体中应变分布规律。

bstract：GFRP bolting has characteristics of high tensile strength and high corrosion re-sistance,but because its low shear strength,distinct brit le fracture phenome-non,it is not widely used in practical engineering,but the application in the temporary support project.by FLAC3D calculated,this paper simulate GFRP bolting strain in dif erent pul ing loads,to study the strain distribution law of GFRP bolting.
