发明名称 An elongate element tensioning member
摘要 <p>An adjustable yield rock bolt that comprises an elongated tensile support member that interacts with at least one gouging member and a receiving member capable of receiving the elongated tensile support member and hold the gouging member segment there between, wherein the elongated tensile support member extends beyond the receiving member a length that corresponds to a predetermined amount of yield before ultimate failure. The bolt has adjustability by allowing for controlled yield by gouging of the elongated tensile support member for any length of displacement.</p>
