摘要
锚杆在岩土介质中的复杂性、多变性,使得锚固能力确定计算十分困难.文章根据对全长粘结锚杆锚固能力试验、作用机理和应力应变模式分析,建立了锚固作用力学模型,导出了参数计算的理论解、设计参数匹配关系及提高锚固能力影响因素,为锚杆支护设计提供了理论依据.
The complexity and changeability of the rock medium into which anchors are put make it rather difficult to determine the anchoring ability. This paper bases on the analysis of the anchoring ability of full-length bond anchor, its functioning mechanism and its stress responding modes, thus have set up the model for anchor functioning mechanics. This paper also deduces the theoretical resolution of parameter calculation, the matching relations of designed parameters, and some factors to improve anchoring ability, and provides theoretical foundation for anchoring technology.
