| Abstract: | 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 bearing 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. |
