文章采用模型试验方法,对3种布孔方式的有孔管桩进行极限承载力试验和应力集中现象试验。试验结果表明:星状布孔方式管桩承载力折减最低,应力集中系数较小,能为有孔管桩设计提供可靠的试验依据。
Using the model test method, the test of ultimate bearing capacity and stress concentration for three kinds of the pipe-pile with hole has been investigated. The results show that the reduce of ultimate bearing capacity of radial opening hole model of pipe-pile is the lowest, and it’ s stress concentration coefficient is smaller relatively. These results can provide reliably experimental basis for the design of pipe-pile with hole.
