在研制出新型伞状抗拔锚并对其进行室内模型试验的基础上,为深入了解其实际应用效果和价值,现进一步对其展开现场实测试验。现场试验主要进行了伞状锚施工工艺的分析研究和承载性能的对比评价,施工工艺方面主要是基于现有传统抗拔桩和抗拔锚杆施工工艺上的改进,承载性能方面主要是通过现场静力载荷试验得出伞状锚的实际承载力,并与理论值进行了对比分析。试验结果表明:与传统抗拔桩相比,伞状锚的施工工艺与之类似,但在承载力方面,在等效条件下,新型伞状抗拔锚承载力的提高非常明显,再次证实了伞状锚的优越性,为其工程推广应用奠定了良好的基础。 On the basis of developing a new type of umbrella-shaped anti-pulling anchor and conducting indoor model test, in order to understand its practical application effect and value, it is further carried out on-site test. The field test mainly carried out the analysis and research on the umbrella anchor construction technology and the comparative evaluation of the bearing capacity. The construction technology is mainly based on the improvement of the existing traditional uplift piles and anti-pull anchor construction technology. The bearing performance is mainly through the scene The static load test results in the actual bearing capacity of umbrella anchor, and compared with the theoretical value. The experimental results show that the construction technology of the umbrella anchor is similar to that of the conventional tensioned pile, but the bearing capacity of the new umbrella-shaped anti-pulling anchor under the equivalent conditions is obviously improved. Once again confirmed The superiority of umbrella anchor has laid a good foundation for the popularization and application of its project.
