摘要
根据悬索桥锚碇的受力特点,提出研究锚碇结构与地层发生剪切滑移的重要性。将锚碇与土体之间发生相对滑移的过程分为3个阶段,解释了各个阶段中剪切滑移的形成发展过程及其机理,给出了接触面在剪切滑移的各个阶段中其剪应力的分布形态以及剪力作用下土体自身产生的切向位移的分布状况。依托某实际工程,按照1:100的比例制作锚碇结构模型,剖析了模型试验现象的原因,验证了理论分析中提出的定性判断结果。
According to the mechanics of anchorage, the importance of researching the interaction between anchorage and ground is discussed. Based on theoretical analysis, the process of the relative-slip between soil and anchorage is composed of three phases; and the mechanism of each phase is explained respectively. And then, the distribution of shear stress in each phase and the distribution of tangential displacement of the interface are presented. After that, a model test of anchorage is carried out with the geometrical scale of 1：100. By analyzing the test results, the propositions in theoretical analysis are performed.
