摘　　要：连续4年实测某滨海电厂挤扩支盘桩沉降,分析了电厂主厂房和烟囱基础沉降及发展特点。通过对软土地基挤扩支盘桩沉降机理的分析,提出了采用半对数坐标法预估最终沉降的方法,并对烟囱的最终沉降进行了预估。Based on 4 years sequential settlement data, foundation settlement behavior of main powerhouse and chimney are analyzed. A semi-logarithmic scale method for forecasting the final settlement is put forward, after discussing the settlement mechanism of pile with expanded branches and plates. The final settlement of the chimney is calculated.
