Assembly type rock anchor rod foundation for power transmission line and simulation method
The invention belongs to the technical field of electric power, and discloses an assembly type rock anchor rod foundation for a power transmission line, which is provided with a prefabricated bottom plate, prefabricated side plates, connecting steel plates, connecting pieces and anchor rods, the prefabricated main column is characterized by further comprising longitudinal bars, grouting holes, foundation bolts, a prefabricated upper main column, adjusting nuts, a prefabricated lower main column, concrete dripping slurry, a reinforcing mesh and mortar. The method has the main beneficial technical effects that the relationship between damage variables and plastic shear displacement is self-defined, and the relationship between shear stress and shear displacement of the contact surface under different shear slip models is simulated; a single-anchor simulation test verifies that bonding contact can effectively reflect residual shear strength characteristics still existing after contact interface damage by adopting a table damage evolution form, and a comparison simulation result adopting the table damage evolution form is closer to an actual condition; overall simulation is carried out, and the reliability and rationality of the modeling method are verified by analyzing the bearing capacity of the foundation in each stage and the stress condition of each component.
本发明属于电力技术领域，公开了一种输电线路用装配式岩石锚杆基础，具有预制底板、预制侧板、连接钢板、连接件、锚杆；其特征在于：还具有纵筋、注浆孔、地脚螺栓、预制上主柱、调整螺母、预制下主柱、混凝土滴浆、钢筋网片、砂浆。本发明具有以下主要有益技术效果：自行定义损伤变量和塑性剪切位移关系，模拟出不同剪切滑移模型下接触面的剪应力与剪切位移关系；通过单锚仿真试验验证了粘结接触采用表格损伤演化形式能有效的反应出接触界面损伤后仍存在的残余剪切强度特征，对比仿真结果采用表格损伤演化形式更加贴近实际情况；进行了整体仿真，通过分析基础各阶段的承载能力以及各部件的受力情况，验证了建模方法的可靠性和合理性。
