摘　　要：本文针对旱田-特克斯公路K111+454处涵洞基础出现的不均匀沉降,通过方案对比,提出钻孔注浆固结法,并详细阐述其施工工艺。该方法简单快捷,施工安全,可操作性和可控制性强,但施工过程中要尤为注意注浆速度、浆液比及注浆压力。实践证明,该方法有效地提高了土体密实度及地基承载力,加固质量满足实际工程设计要求。In this paper, the non-uniform settlement of culvert foundation at K111＋454 of Hantian-Tekesi road isproposed.The grouting consolidation method of borehole and elaborate construction technology have been put forwarded through scheme comparison.This method is simple, quick, safe, operable and controllable, but the groutingspeed, slurry ratio and grouting pressure should be paid special attention in the construction process.The practicehas proved that the method can effectively improve soil compactness and bearing capacity, and the reinforcementquality meet the actual engineering design requirements.
