砂固结锚固室内试验及砂土强度特性理论的再认识
LABORATORY TESTING STUDY ON SAND-CONSOLIDATED- ANCHORAGE-PRESTRESSED BOLT AND NEW SUGGESTION ON SAND STRENGTH THEORY
【摘要】 砂固结内锚头预应为锚杆的锚固力是由砂体与锚孔壁之间的摩擦力提供的,设计的室内试验测出了摩擦力的分布曲线,基于本试验成果对目前的砂土强度特性理论提出了一些看法。
【Abstract】 The anchorage force of consolidated-anchorage-prestressed bolt is actually the friction resistance between sand and drill hole. The friction resistance curve is gotten through laboratory tests. Based on these tests some new suggestions on sand strensth theory are proposed.
