摘　　要：以刚性桩复合地基应力场试验结果为基础,考虑负摩阻力的影响,将垫层视为弹性体来考虑垫层压缩和桩刺入对沉降的影响,分别应用Geddes解和Boussinesq解计算桩身荷载和桩间土荷载在地基中产生的竖向应力,得到刚性桩复合地基沉降的简化计算方法。A method for the settlement calculation of composite foundation with rigid piles is presented, based on the tests of stress distribution. Impact of negative friction, cushion compression and penetration are also considered. Cushion is considered to behave the same as elastomer; Geddes＇ stress method and Boussinesq＇ stress method are used to calculate the vertical stresses.
