松散介质内大吨位长锚索的受力研究

Study on Big Tonnage and Long-anchor's Stress in Loose Substance

本文以川藏公路102滑坡群2#滑坡加固及高筑填路堤修筑工程为例,采用有限元法,按不同单元及不同的施工顺序进行了锚索受力分析计算,探讨了松散介质内大吨位长锚索在穿过高筑填路堤、滑坡体、滑面、稳定松散介质后的应力分布特征及施工顺序对应力分布的影响。具有一定的理论探讨和工程实践意义。

Based on the 2# landslide reinforcement project of 102 landslide group at Chuanzang highway, using the finite element method, calculates and analyses the anchor's stress according to different unit and work sequence, discusses the stress distribution properties of the big tonnage long-anchor when it dill through the high fill-back embankment, landslide mass, landslide face, and the stable loose substance in turn.The results show that the work sequence has a large effect on the stress distribution.
