| 摘 要： | 针对锚杆抗滑桩的研究现状,设计了三种不同嵌固深度的锚杆抗滑桩,桩体及嵌固岩体以环氧树脂作为模型材料,进行了光弹试验,来研究嵌固在岩体中锚杆抗滑桩的受力特性。通过观测桩体及嵌固岩体的等差线条纹变化规律,以及测试锚杆拉力的变化,定性得出了抗滑桩桩体内力的分布规律、桩体的应力集中问题及出现位置和锚杆拉力的变化与桩体嵌固深度的关系等问题,这与普通抗滑桩的受力特性有很大不同。

| Abstract: | According to the research status of anchored pile,three types of anchored piles with different embedded depth are designed,based on epoxide resin as pile body and fixed rock mass,and photoelastic experiments are conducted to study the mechanical characteristics of anchored piles against landslide which are embedded in the rock mass.Through the observation of pile body and the isochromatic fringe variation of fixed rock mass,testing the change of anchor tension,the paper qualitatively gets the distribution r... |
