【摘要】 影响航道整治建筑物安全稳定性的因素是众多且复杂的。实际工程中,主要影响因素有材料因素、结构型式、人为因素和环境因素等。而这些因素往往具有不完全性、未知性。评定航道整治建筑物安全稳定性实质上是灰色系统问题。根据影响航道整治建筑物抵御水流泥沙破坏作用的主要因素,建立航道整治建筑物安全稳定性的灰关联评定模型,并进行了模型丁坝实例计算。分析表明,该模型使用方便,评定结果科学可靠,具有实用价值。更多还原

【Abstract】 The factors influencing on safety and stability of regulating structures in a channel are numerous and complicated. In the actual engineering, the main influencing factors include material factor, structure pattern, human factor and environmental factor. And these factors often have the features of incompleteness and uncertainty. So the evaluation on safety and stability of regulating structures in a channel is a grey system theory problem. Based on the main influencing factors that regulating structures resist the damage and sediment, the grey correlative evaluation on safety and stability of regulating structures in a channel is developed. The model is used for a spur dike calculation. The results show that the method is reasonable, practical and convenient to use.更多还原
