摘要
通过对国内 30余例锚固工程试验资料的统计分析 ,在讨论影响岩体与锚固体间粘结强度因素的基础上 ,提出了确定预应力锚索内锚固段与岩体间粘结强度的经验公式 .为便于设计人员确定内锚段长度 ,建立了内锚段长度设计系数图 .实例计算表明 ,所提供的确定方法与岩锚试验结果较为吻合 .
Based on statistic analysis of 30 anchoring projects in China and discussion of the factors affecting the cohesive strength between the rock mass and grouted part of prestressed anchor cables, an empirical formula of anchorage cohesive strength and rock mass property is proposed. For the convenience of design of the length of the grouted part, a graph of design coefficient is provided. Finally, an example is given, which shows that the result calculated with the present method and the test result are in good agreement.
