摘　　要：根据生石灰挤密桩吸水膨胀固结脱水的原理,提出了生石灰挤密桩的设计方法,从土壤的孔隙比变化入手,找出桩管直径d和有效挤密半径R的关系式,并提出了复合地基承载力的确定方法,以供类似工程参考。According to the principles of quick-lime sealed pile water expended reinforced and dehydration,it brings forward designing methods of quick-lime sealed pile.Based on earth hole rates changes,it finds out the formula between pile radius d and valid sealed radius R.It also brings forward fixing methods of compound basement capacity,so as to make reference for familiar projects.
