坑式钢管静压桩在地基加固中的应用

Application of Pit Type Steel Pipe Static Pressure Pile in Foundation Reinforcement

摘要:

坑式钢管静压桩是解决既有建筑物因软弱土层地基产生沉降变形的一种技术方法。针对山西北化关铝化工有限公司质检楼地基沉降变形及工程地质条件，提出了采用坑式钢管静压桩进行加固处理的设计方案，介绍了坑式钢管静压桩施工方案和施工流程及注意事项；总结了施工过程中遇到的问题，并对施工后的监测数据进行了分析。结果表明，坑式钢管静压桩施工对软弱地基加固效果良好，可成功地解决软弱土层产生的地基沉降开裂问题。

Abstract:

The pit type static pressure steel tube pile is a technical method to solve soft soil foundation deformation of existing buildings due to subsidence. According to the foundation deformation and geological conditions of the inspection building of Beihuaguan Aluminum Chemical Company LTD. in Shanxi Province, a design was proposed for reinforcement by using pit type static pressure steel pipe piles with the construction schemes, construction processes and notes described. The problems encountered in the construction process are summarized with the monitoring data after construction analyzed. The results show that pit type static pressure steel tube piles are effective for soft foundation reinforcement and can successfully solve cracking of the foundation due to settlement of the soft soil layer.
