桥涵基础沉降生石灰桩处治技术应用

Application of quicklime pile processing technology of culvert foundation settlement

结合某高速K28+300涵洞雨季遇水沉降开裂病害,采用石灰桩对地基进行处理,并对地基加固原理、施工工艺、控制要点等内容进行了探讨。工程实践证明该方法技术简单,且经济合理,能够有效地减少软弱基础的工后沉降,提高软土层的承载力,可为类似病害处理提供参考。

Combining with the highway culvert K28 ＋ 300 settlement cracking diseases in rainy season,the thesis deals with the foundation by applying quicklime pile,explores the foundation reinforcement principles,construction technology and control points. The engineering practice proves advantages of the above-mentioned technology,such as simple technology,economic and rational,effectively reducing he weak foundation settlement after construction,and improving soft soil layer bearing capacity,which has provided some guidance for processing similar diseases.
