摘要: 为把CFRP筋锚杆更好地应用到岩土锚岩中,制作三丝7CFRP筋压车型锚杆,通过场地试验,对锚杆的极限承载力、锚头位移和锚固体应变进行理论分析,并形成一套压力型CFRP筋锚杆的制作和施工工序。Abstract: For the CFRP tendons being better applied to the rock bolt anchor,three-wire 7CFRP bar pressure-type anchor specimens were made.Through field tests it was analyzed theoretically the ultimate bearing capacity of anchor,displacement of the anchor head and the anchorage boby strain,by which it was formed a set of procedures of fabriction and construction of pressure-type CFRP tendon anchor.
