| 摘 要： | 以某地铁工程区间隧道为例，采用通用的FLAC程序对盾构区间隧道施工在不同注浆压力条件下引起的地表沉降及围岩变形进行了数值模拟研究。根据该分析结果，综合考虑在工程地面条件允许的沉降范围内，提出了合理的盾构施工同步注浆压力及相应的控制沉降措施。

| Abstract: | Taking the running tunnel of a Metro project as an example, this paper discusses the surface settlement and surrounding rock deformation arising in shield tunneling under different grouting pressures by means of FLAC program. Considering the allowable surface settlement range, the authors propose reasonable simultaneous grouting pressures and settlement control measures in shield tunneling construction. |

| Keywords: | shield tunnel grouting pressure settlement numerical simulation |
