摘要
介绍了桩基施工过程中的桩底沉渣及泥皮问题对基桩承载力及沉降量的影响,指出后注浆技术可以有效消除这一问题,结合太原某工程实例,阐述了后注浆技术的应用并对承载力的提高进行分析,以期对类似工程提供宝贵的工程经验。
The paper introduces the influence of the sediment at pipe-tip and mud cover in the construction of the pile foundation on the loading capacity and the settlement of foundation piles,points out the post-grouting technique can eliminate the problem and analyzes the application of the technique and its improvement for the loading capacity by combining with some engineering practice in Taiyuan,so as to provide some precious engineering experience for similar projects.
