摘要
为了提高锚索的承载能力和使用寿命,设计了新型球面锚索锚具,通过锚索静载拉拔实验,模拟锚索在应用中可能出现的各种情况,调节锚索中心线与锚固面的角度,加载直到破坏。通过新型球面锚索锚具与普通锚索锚具的实验数据分析,验证球面锚索锚具有更好的承载能力和减弱剪切应力的能力,从而为新型锚索锚具的应用提供了理论依据。
In order to improve the load - bearing capacity and useful life of anchor cable, design new anchor cable anchorage, through static load drawing experiment of anchor cable, simulation the various situations may arise in application, regulation angle between the centerline anchor cable and the anchorage face, loading until destruction. Analyze the experimental data of new spherical anchor cable anchorage and general anchor cable anchorage, proof the spherical anchor cable anchorage has better load - bearing capacity and reduces the ability of shear stress, and provide a theoretical basis for the application of new anchor cable anchorage.
