摘要
文中依托工程实例,对高压喷射扩大头锚杆的施工技术进行分析,通过现场试验检测锚杆的施工质量,并与普通的锚杆技术进行经济性对比.结果表明,锚杆的位移与加载呈正相关,锚杆的荷载-位移曲线离散性较小,且测试过程中锚杆未被破坏,抗浮锚杆具有良好的施工效果.
Abstract
Based on engineering examples,the construction technology of high pressure jet expansion head bolt is analyzed,the construction quality of bolt is tested by field test,and the economic comparison is made with common bolt technology.The results show that the displace-ment of the bolt is positively correlated with the loading,the dispersion of the load-displacement curve of the bolt is small,and the bolt is not damaged in the test process,and the anti-floating bolt has good construction effect.
