| Abstract: | 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. |
