基于应用的GFRP锚杆拉伸和剪切性能试验研究

Study on tensile test and shear test of GFRP bolt on the bases of its application

摘要: 为探索玻璃钢纤维增强塑料(GFRP)锚杆在矿山中的实践应用,在经典拉伸、剪切试验模型的基础上,结合GFRP复合材料独特的受力特性,对GFRP锚杆进行了改进的拉伸和剪切试验。详细介绍了拉伸试验试件锚具的制作。较为准确的得到了GFRP锚杆的拉伸、剪切实验参数及破坏形态。试验结果为GFRP锚杆在矿山推广应用中,科学确定支护参数和支护操作制度提供了基础依据。

Abstract: In order to probe the GFRP anchor practically applicate in mine,and on the bases of classic model of tensile test and shear test, combined with the unique features of GFRP bolt, the text record GFRP anchor improved tensile and shear test. The tensile test sample of GFRP anchor is presented in detail.And it get a more accurate tensile & shear test parameters and failure modes of GFRP bolt.The results can be the foundation of scientifically determining the parameters and operation system in the application of GFRP bolt.
