| 摘 要： | 针对基桩竖向承载力自锚法测试体系中桩底嵌岩压力型锚杆的受力特点,基于Kelvin问题的弹性位移解,并结合锚固体-岩石作用的剪胀机理,推导了压力型锚杆应力分布的弹性解.基于所获得的解答,分析了桩底嵌岩锚杆锚固段应力沿锚固长度的分布规律,并分析了各种岩土参数变化对锚固段剪应力分布的影响.结果表明:桩底嵌岩锚杆锚固段上的正应...

| Abstract: | According to the mechanical characteristics of compression type rock-socketed anchor rods under pile toe in the system of vertical load-bearing capacity test of pile foundation by the self-anchored technique,an elastic solution for stress distribution of compression type anchor rods was derived based on the Kelvin's solution of elastic displacement and the dilatancy effect between anchorage body and surrounding rock.Then,the distribution of stresses of rock-socketed anchor rods under pile toe along the anch... |
