考虑界面软化特性的土层锚杆拉拔受力分析
Pullout mechanical analysis of soil anchor based on softening behavior of interface
摘要
Abstract
Based on interface stick-soft-slip constitutive model presumption, the differential equation of soil anchorage mechanics and analytic solutions were presented. Under different pullout loadings, distribution pattern of anchor shear stress have three types, i.e. elasticity, elasticity-soften, and elasticity-soften-slip, but the three types do not all appear, to an anchorage engineering, and are restricted by physical and mechanical properties of materials. So, the internal relations among distribution pattern of anchor shear stress, ultimate pullout loading and destructive characteristics are analyzed, and discriminant criterions and ascertain methods are presented. At the same time, with the anchor pullout test data, the feasibility of method is verified by calculation and contrastive analysis.关键词
