摘要
砂固结预应力锚杆的锚固力是由砂体与锚孔壁之间的摩擦力提供的。设计了室内试验和现场试验 ,并对这项技术作了深入地研究。基于室内试验成果 。
The anchorage force of sand consolidated anchorage prestressed bolt is actually the friction resistance between sand and drill hole. Through laboratory and field tests, a thorough study is made on the sand consolidated anchorage prestressed bolt. Based on lab test, a numerical simulation is carried out for the field test, and some useful results are obtained.
