【摘要】 液压静力压桩机是一种大型桩基础施工设备,其工作可靠性问题十分重要,由于液压系统的故障往往带有模糊灰色性,传统的评价方法很难对其进行正确的评价。利用模糊灰色理论,构建了基于模糊灰色理论静力压桩机工作评价可靠性模型,经过试验研究证明,利用该方法对静力压桩机进行评价,其评价精度、可靠性较传统方法显著提高。更多还原

【Abstract】 Hydrostatic pile press is a kind of large-sized construction equipment for pile foundation. Its operation reliability is a very important problem. Due to the fuzzy gray feature of hydraulic system failures, it is difficult to get a proper evaluation with conventional evaluation methods. A fuzzy-gray-theory based model to evaluate operation reliability of hydrostatic pile press is established with fuzzy gray theory. Test and research show that accuracy and credibility of the evaluation are significantly increased with the method compared to conventional method.更多还原
