摘　　要：湿软地基存在低承载力、大沉降量、长固结时间等弊端,地基沉降对建成后的路面质量、行车速度以及使用寿命等关键性问题影响重大。为保证地基安全,结合数字化测绘技术,提出一种沉降变形量预测方法。根据某高速公路的一个湿软地基沉降标埋设情况与各项指标归一化数据,得到该地基沉降测绘图与预测曲线,表明所提方法能够有效预测沉降变形量,且具有比较理想的精准度,与实际测量值拟合度较高。The wet soft foundation has the disadvantages of low bearing capacity,large settlement and long consolidation time.The foundation settlement has a great impact on the pavement quality,driving speed and service life.In order to ensure the foundation safety,a settlement deformation prediction method based on digital mapping technology is proposed.According to the embedded condition of a wet soft foundation settlement mark and the normalized data of each index,the mapping map and prediction curve of the foundation settlement are obtained.The results show that the proposed method can effectively predict the settlement deformation,and has ideal accuracy,and has a high degree of fit with the actual measured value.
