1煤矸石粉填料在沥青混凝土中的应用显示文摘该文的研究目的是探究煤矸石粉作为填料对沥青混凝土路用性能的影响规律。从洗煤厂取煤矸石样品后,将其破碎加工成天然煤矸石粉填料;将天然煤矸石粉在750℃下充分燃烧,制成煤矸石灰填料。X射线衍射试验结果表明:煤矸石粉和煤矸石灰中的火山灰成分使其可以作为活性填料应用于沥青混凝土中。主要进行了以下室内试验:干燥和饱水条件下马歇尔稳定度试验、间接拉伸强度和回弹模量试验。试验结果表明:与掺传统石灰石粉填料的沥青混合料对比,煤矸石粉和煤矸石灰沥青混合料具有更高的高温稳定性和回弹模量;煤矸石粉和石灰石粉作为填料等比例掺配应用于沥青混合料中,可以使其获得更高的水稳定性,而且煤矸石灰比煤矸石粉对混合料水稳定性的改善效果更为显著;由间接拉伸强度试验中的应力应变曲线可以得到混合料的韧性指标,该指标可以表征材料的能量吸收力或柔韧性,煤矸石粉沥青混合料的韧性比石灰石粉沥青混合料更好。赵梦龙 冯新军 唐雄 Amir Modarres Morteza Rahmanzadeh 2017中外公路2017,37,6:11
2煤矸石粉与传统填料沥青混凝土力学性能和环境影响的对比研究显示文摘由于自然资源日益枯竭,各行各业对于废物利用的需求显著增长。煤矸石是在煤的开采、加工过程中产生的副产品,其在自然环境中的累积引起了一系列经济和环境问题。为了研究煤矸石粉在道路工程中的适用性,通过马歇尔稳定度、间接拉伸强度、水稳定性、回弹模量和耐疲劳性能试验,对煤矸石粉热拌沥青混凝土与石灰石粉、沸石粉和普通硅酸盐水泥等传统填料热拌沥青混凝土进行力学性能对比。结果表明:与石灰石粉和沸石粉相比,煤矸石粉尤其是煤矸石灰作为填料改善了热拌沥青混凝土的力学性能,而煤矸石灰沥青混凝土和普通硅酸盐水泥沥青混凝土有几乎相同的力学性能。另外,采用毒性特征浸出程序(TCLP)来评价煤矸石粉沥青混凝土对环境的影响,结果表明:不同试验样品的重金属浓度在很大程度上小于标准值。因此将煤矸石粉作为填料应用在热拌沥青混凝土中不仅可以获得优良的力学性能,而且还可以有效减少煤矸石对环境的污染。冯新军(编译) 赵梦龙(编译) 李猛(编译) amir modarres morteza rahmanzadeh pooyan ayar 2017中外公路2017,37,5:9
3PRODUCTION PLANNING PROBLEM WITH PRICING UNDER RANDOM YIELD:CVAR CRITERION显示文摘In this paper,we address a basic production planning problem with price dependent demand and stochastic yield of production.We use price and target quantity as decision variables to lower the risk of low yield.The value of risk control becomes more important especially for products with short life cycle.This is because,the profit implications of low yield might be unbearable in the short run.We apply Conditional Value at Risk(CVaR) to model the.risk.CVaR measure is a coherent risk measure and thereby having nice conceptual and mathematical underpinnings.It is also widely used in practice.We consider the problem under general demand function and general distribution function of yield and find sufficient conditions under which the problem has a unique local maximum.We also both analytically and numerically analyze the impact of parameter change on the optimal solution.Among our results,we analytically show that with increasing risk aversion,the optimal price increases.This relation is opposite to that of in Newsvendor problem where the uncertainty lies in demand side.Saman Eskandarzadeh Kourosh Eshghi Mohammad Modarres Yazdi Mohsen Bahramgiri 2014Journal of Systems Science and Systems Engineering2014,23,3:3
4多堆核电场址概率风险评价中的始发事件分析显示文摘绝大多数核电厂概率风险评价均以单个反应堆为单位,安全目标的制定也是如此。事实上,同一场址(site)上有多座核电厂(plant)、同一厂址(plant)上有多个反应堆(reactor)的情况并不罕见。为将概率风险评价从单个反应堆推广至整个场址,本文在定义场址风险的基础上,针对始发事件展开分析,给出其分类及识别方法建议。分析表明,多堆场址的始发事件可归入2类单堆始发事件,以及3类多堆始发事件。此结果是开展多堆场址概率风险评价的第1步,具有重要价值。张赛 童节娟 Modarres Mohammad 2017原子能科学技术2017,51,8:3
