摘　　要：钢混组合桩结合了混凝土管桩造价低和钢管桩抗弯性能好的优点,在满足工程质量要求的前提下降低成本。结合工程实例开展钢混组合桩沉桩动应力测试,对联接段的应力传递效果进行研究。结果表明:联接段设计合理,能起到很好的应力传递作用。The steel concrete composite pile combines the low cost of concrete cylinder pile and good flexural performance of steel tubular pile, and reduces the cost under the premise of satisfying the project quality requirement.Combining with the engineering practice, we carry out the dynamic piling stress test to study the effect of the stress transfer by the connecting section. The results show that the design of the connection section is reasonable and it plays a good role of stress transfer.
