摘要

摘要: 劲性复合桩是在水泥土搅拌桩初凝前将芯桩插入其中,形成共同受力的一种新的复合桩型。在前人研究的基础上,以某工程项目为背景,进行了大量试桩试验,包括一般管桩与水泥土-管桩复合桩,并量测了复合桩中桩身轴力的传递,为其他类似工程项目提供参考。试验采用慢速维持荷载法检测试桩的承载力,试验结果表明水泥土-管桩复合桩的承载力相对于一般管桩有较大提高,能够满足工程提出的承载力要求,较大幅度地减少了工程造价,具有较高的经济效益。

Abstract: The strength composite pile is a new type of composite pile that a core pile is inserted into a deep cement mixing pile before the initial set. Based on the previous studies and a project case, load tests are conducted on a great number of test piles including pipe piles and composite piles, and the axial force of composite piles is measured. It will provide a beneficial reference for other similar projects. The slow maintenance loading method is adopted. The test results show that the bearing capacity of the strength composite pile increases obviously compared with that of the pipe pile, and it meets the requirements of engineering construction. Besides, the cost of the composite pile decreases significantly.
