基于模糊灰色理论液压压桩机工作可靠性评价方法

The Research of the Reliability of Hydraulic Pressure Static Force Pile Driver Based on Fuzzy and Grey Systems Theory

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,由于其各影响因素之间存在灰色模糊特征,传统评价方法很难对其进行正确的评价。本文利用模糊灰色理论,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。

Hydraulic pressure static force pile driver is large construction equipment, and its reliability is very important. The traditional evaluation methods are difficult to make proper evaluations due to its affecting factors with fuzzy and grey characters. In this article the fuzzy and grey systems theory is employed to construct a evaluation model of the hydraulic pressure static force pile driver. The experiment results show that the evaluation precision and reliability of this method are better than that of the traditional ones.
