【摘要】 本文主要通过试验研究分析了钢绞线与水泥浆体(以下简称浆体)结合面粘结—滑移特性,根据实测的粘结应力和滑移量值,用最小二乘法原理给出了粘结—滑移关系的数学模型,为确定预应力锚固沐系内锚头长度和承载能力以及用非线性有限元法分析其破坏机理提供了必要的条件。更多还原

【Abstract】 An experiment is conducted to study the bond-slip behavior between strand tendon and cement grout in this paper. With the least square method a mathematical model about the relationship between bond and slip is established based on the experimental data of bond stress and slippage. The model contributes a necessary condition for determining the length and the bearing capacity of anchor-root in prestnessed anchoring body and analyzing the fail mechanism of anchor-root by non-linear finile element method.更多还原
