摘　　要：根据部分已有工程经验,结合路基及堤坝等复杂荷载作用下软土地基的强度计算方法和汉森公式,提出可用于充砂模袋围堰稳定计算的设计方法。The sand-filled geotextile tube cofferdam is applied to coastal soft soil foundation. However, the stability calculation result of frequently used circular slide methods is quite different from the practical project. Base on engineering experience,combined with the structural strength calculation method of soft soil foundation and Hansen formula under complex loads,a design method for the stability calculation of sand-filled geotextile tube cofferdam is proposed.
