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 ,对现场试验作了数值模拟分析
The anchorage force of the sand consolidation prestressed anchor is provided by the friction between the sand body and the anchor hole wall. The interior test and the field test are designed, and the technology is deeply studied. Based on the laboratory test results, numerical simulation analysis of the field test was made
