摘　　要：将正常工作状态下的土钉分为主动区土钉段和稳定区土钉段,并根据土钉的受力特点,分别建立了受力与变形关系的计算模式.该计算模式的建立为土钉支护及复合土钉支护中土钉变形计算提供了依据,从而为进一步计算土钉支护以及复合土钉支护的变形创造了条件.In this paper, soil nails in service are divided into two segments, active area segment and anchor area segment. Based on the characteristics of soil nail force, the calculation mode of force and deformation for each part are established. What we have done here provides basis for the deformation calculation of soil nails in soil nailing and composite soil nailing, and creates conditions for the deformation calculation of soil nailing and composite soil nailing.
