摘　　要：我国中东部地区古遗址土层存在大量粉质黏土,楠竹加筋复合锚杆加固技术在该地区应用较少。本文通过建立楠竹加筋复合锚杆与粉质黏土锚固段相互作用的有限元模型,针对典型土层力学参数,分析了内粘结剂模量、外粘结剂厚度对锚固段应力分布状态的影响规律。结果表明,外粘结剂厚度对土层应力影响较大,内粘结剂模量对杆体内各部件应力分布影响较小,分析得到的数据能为该加固技术在华北地区的应用提供设计参考。There is a large amount of silty clay in the central and eastern part of China earthen archaeological sites, and the reinforcement technology of Bamboo-Steel Composite Anchor is seldom used in this area. In this paper, the finite element model of the interaction between Bamboo-Steel Composite Anchor and silty clay anchorage section was established. According to the mechanical parameters of typical soil layer, the influence of the internal binder modulus and the thickness of external binder on the stress distribution of anchorage section were analyzed. The results showed that the thickness of external binder had a great influence on the soil stress, while the internal binder modulus had a little influence on the stress distribution of the components in the model. The data obtained from the analysis can provide design reference for the application of the reinforcement technology in the central and eastern part of China.
