【摘要】 从理论上研究了锚杆-土之间相互影响的机理和现象，认为铺杆-土界面摩擦力的增量的主要影响因素是土的剪胀，提出了硬化和软化土中铺杆-土界面模型．应用这个模型，在给定界面参数条件下可预测锚杆的特性，或根据给定的锚杆抗技试验结果，可以确定界面参数．更多还原

【Abstract】 In this paper, the mechanism and the phenomena of the anchor-soil interaction were studied, and the soil dilatancy was regard as the main factor contributing to the increase of the anchor soil interface. The anchor-soil interface mode1s have been developed for hardening and softening behav ior, with which one can predict the anchor pertbrmance for the given interface parameters, and to determine the interface parameters from the given anchor pull-out test respectively This may reduce a lot of anchor pull-out test and obtain reliable anchor performance data for anchor’s design with high econo1nic benefit.更多还原
