摘要 运用弹性力学空间轴对称问题与剪切位移法的基本假定和解答方法,建立分析模型和界面应力基本方程,得到化学植筋的界面应力和植筋轴力的弹性解析解答,结合算例说明了界面应力的衰减曲线分布规律,提出载荷传递系数k并简要分析了它对载荷传递规律影响. Using basic assumptions and solutions of spatial axisymmetric problems of elasticity and the shear displacement method,an analysis model is proposed and the basic equations,are deduced with analytical solutions,which illustrate the attenuation curve with an example,together with the load transfer coefficient k and its influence on the load transfer law.
