摘　　要：本文在分析国内外大量文献资料的基础上,对土钉面层的受力机制进行了详细的讨论和分析,认为土钉面层主要受到钉体对面层的集中荷载及土体对面层的分布荷载作用。引入半弹性体和布辛涅奈斯克理论推导出了较为实用的土钉面层配筋量计算公式,并通过实例验证了该公式的正确性。Based on lots of domestic and international references, the paper discusses the mechanical mechanism of soil nailing faceplate in detail. It is considered that soil nailing faceplate bears concentrated load from nail and distributed load from soil. Semi-infinite elastic body and Boussinesq theory are introduced to deduce the practical formulas for calculating reinforcement ratio of soil nailing faceplate. Through analyzing an example and comparing with the practical situation, the formulas are validated to be correct.
