摘要
研究预应力锚索框架与岩土体的相互作用机理及施加预应力产生的附加应力 ,以福建省漳 (州 )龙 (岩 )高速公路和溪段 K63 +73 0~ 95 0与 K64+690~ 790边坡的锚索框架加固为工程实例 ,在对预应力锚索框架结构力学作用机理分析的基础上 ,建立相应的三维地质力学模型 ,应用 FLAC3D快速拉格郎日差分程序对此进行数值模拟 。
The structure of frame beam with prestress cable is a new anti slide structure. It has been used on the road chasm slope more and more widely with the construction of express web in mountainous areas. By now, only a little research has been made on the interaction between frame beam with prestress cable and rock and soil and the subsidiary stress induced by prestress. But the structure design must be based on their researches. Therefore, the authors select on the slope in Hexi K64+690~790 of Zhangzhou Longyan express highway in Fujian Province as a case in this paper. And based on the research of mechanism , a three dimension geological model is established. Then, the authors carry out the numerical simulation with FLAC 3D (Fast Lagrangian Analysis of Continua) and make an elementary research on the distribution of subsidiary stress.
