摘　　要：长短桩复合地基工作性状研究,已逐步成为理论和工程界关注的热点.通过2组刚性短桩、3组刚性长短桩复合地基,6组单桩承载力的现场试验,研究了刚性长短桩复合地基的工作性状,提出考虑桩"上刺"的刚性长短桩复合地基承载力的计算新方法,具有较强的工程实用性,可供理论研究参考和指导工程设计.It has become a theoretical and engineering concern at the summit, to study long-short-pile composite foundation working mechanism. From the field-test of three groups short-rigid-pile composite foundation,three groups long-short-rigid-pile composite foundation and six groups single-pile load bearing capacity,the beating capacity of Long-short-pile composite foundation was analyzed, and a new calculation method to compute the bearing capacity of rigid long-short-pile composite foundation considering the pile ＂upper-penetration＂, was put forward. The method is of strong engineering adaptability,and serves as a reference to theoretical research and guide of practical designing.
