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。设计了一系列室内试验对这项技术深入地作了研究。基于试验成果对砂固结锚固机理作了探讨。
The anchorage force of the sand consolidation prestressed anchor is provided by the friction between the sand body and the anchor hole wall. A series of in-house experiments were designed to study this technique in-depth. Based on the experimental results, the anchoring mechanism of sand consolidation was discussed.
