桥梁桩基承载力性状的测试新技术研究

A New Technique to Determine Pile Bearing Capacity for Bridge Foundation

根据桥梁桩基工程中荷载传递规律的特点，分析了桩基承载力现场测试技术和方法，认为Ｏｓｔｅｒｂｅｒｇ测桩法是桩基测试的革命．通过室内初步试验结果和现场的工程实例介绍了Ｏｓｔｅｒｂｅｒｇ测桩法的原理、应用现状及存在问题，认为该测桩法适合于桥梁桩基载荷试验并确定桩基承载性状，对大型桥梁桩基测试意义重大，在工程实践中具广阔的应用前景．

According to the load transfer in bridge pile foundations, the techniques and methods of pile bearing capacity are analyzed. The advantages and disadvantages of Osterberg's load test are discussed in this paper. It shows that Osterberg load test system is available for determining the bearing capacity of bridge pile foundation.
