摘　　要：基于现场试验结果,文章对某公路边坡治理中的压力型锚索在分级循环加、卸载作用下,锚固段砂浆体的应变分布规律及变化趋势进行试验研究及分析,获得了压力型锚索锚固段砂浆体在各工况下的应变主要分布区段位置和长度,可为危岩治理设计合理确定锚固深度提供实测依据。The paper has carried out test study and analysis of strain distribution law and variation tendency of mortar mass in anchorage section under circulating loading and unloading in stages of pressure type anchorage cables in side slope treatment of a mad based on the in - situ test results respectively, and then verified both locations and lengths of major strain distribution zones of the mortar masses of pressure type anchorage cable anchored sections under various working conditions, which provides measured basis for designing and proper determination of anchorage depth in treatment of dangerous rocks.
