| 摘 要： | 高地下水位地区构筑地下建(构)筑物必须解决结构上浮问题,抵抗上拔荷载作用已成为地下工程建设中经常需要面临的问题。试验表明爆扩桩具有很好的抗浮能力,其成桩施工工艺方面的研究也比较完善,但是对爆扩桩的承载机理的研究很少,通过运用NCAP-1有限元计算程序,分析总结爆扩桩的抗拔承载机理。

| Abstract: | The buoyance of underground structure in a high ground water level area is a problem needing solution,so the anti-pullout mechanism of underground structure has become an important research topic.It is shown from the test results that the explosion-expanded pile has good anti-buoyance capacity, and its pile-forming technology is also perfect,but the study on the pile loading mechanism is deficient.In this paper,the NCAP-1 finite element computational program is used to analyze the anti-pullout loading mechanism of explosionexpanded pile. |
