玻璃纤维增强塑料(GFRP)筋能替代钢筋作为土钉支护材料。以某工程基坑开挖支护为背景，利用有限元进行 GFRP 筋和钢筋土钉支护的仿真分析与比较。结果表明，GFRP 筋的受力随着开挖深度增加呈现较平稳的增长， GFRP 筋的受力增长幅度明显要小于钢筋，整个施工过程中钢筋的受力比 GFRP 筋大。在一定埋深范围，两种材料土钉受力分布相似；GFRP 筋土钉体受力分布更均匀，在埋深越大的筋体段，受开挖深度影响越大，承力变化更明显。利用仿真分析有助于研究 GFRP 筋土钉受力分布和作用机理。

Replacing the reinforcement as soil nailing,GFRP bars have obvious differences in mechanical properties with the reinforcement. According to a excavation engineering,two different materials of soil nailing were simulated and compared by finite element soft. The results show that the force of GFRP bars increase steadily with the depth of excavation,and the force growth rate of GFRP bars is significantly less than the reinforcement. Throughout the construction process,reinforcement force is larger than the GFRP bars. In a certain depth range,the force distribution of both materials soil nailing are similar. The force of GFRP soil nailing is more evenly distributed. In deeper place,GFRP soil nailing are impacted more significantly by excavation depth,and force changes of GFRP soil nailing are more obvious. Software simulation contributes to research on force distribution and mechanism of GFRP soil nailing.
