高强耐磨贝氏体道岔尖轨的研制

在贝氏体钢轨及贝氏体辙叉研究的基础上,通过成分选择、精炼、精轧及稳定化处理,制成60AT贝氏体钢轨,再加工成贝氏体道岔尖轨。通过对60 AT贝氏体钢轨以及异型钢轨性能的检验可知:60 AT贝氏体钢轨以及异型钢轨全断面抗拉强度、屈服强度和伸长率等均达到相关标准规定的要求,并且强韧性配合非常好;贝氏体道岔尖轨强韧性指标明显地优于珠光体道岔尖轨,同时不需要进行淬火处理,就可以保证全断面具有高且均匀的硬度。通过大秦线的铺设试验可知:贝氏体道岔尖轨无严重的剥离掉块等疲劳伤损;耐磨性能相比珠光体尖轨具有明显优势,使用寿命约为珠光体道岔尖轨的2倍。     

社区步行通达性对独栋住宅房价的效益评估--美国德克萨斯州奥斯丁市空间特征分析

通过分析美国德克萨斯州奥斯丁市2010—2012年独栋住宅的销售价格,以街道智慧步行指数(Street Smart Walk Score)和人行道密度(Sidewalk Density)作为衡量指标,研究社区步行通达性对房价的影响。使用Cliff-Ord空间特征模型(即广义空间模型,General Spatial Model,或者SAC)控制空间自相关影响。结果表明：在依赖小汽车的社区通过增加设施可达性来提升步行通达性的举措并不能提高房价;增加人行道也只能最小限度地提高房价。投资社区便利设施和人行道对适宜步行社区的房价提升效果比依赖小汽车的社区显著。     

压实黄土的路用性能试验研究

用常规压实方法制备不同压实功能下的土样,来研究压实黄土的工程性质。试验结果表明：压实黄土的压缩模量、粘聚力及内摩擦角随击实功的增大而增大;不同击实功下土样的强度随龄期基本呈增长趋势,但其增长幅度与试验过程中的压应力大小有关;同一龄期土样的粘聚力随击实功变化幅度较大,而内摩擦角随击实功变化幅度较小。

The effect of road traffic noise on the prices of residential property – A case study of the polish city of Olsztyn

The key factors that determine the prices of real estate are location, technical standard of property as well as the local environment. In urban agglomerations, road traffic noise has a considerable impact on the purchasing decisions made by apartment buyers. This is a widespread problem in Central-Eastern Europe. The main objective of this study was to verify the working hypothesis that apartment prices are correlated with traffic noise levels in Olsztyn, the capital city of the Region of Warmia and Mazury in north-eastern Poland.The study was carried out in four principal stages. Firstly, traffic noise intensity was determined for apartments (objects of real estate transactions concluded in 2013), based on an acoustic map for the city of Olsztyn. The map was developed in line with the provisions of Directive 2002/49/EC of the European Parliament and of the Council of 25 June 2002 relating to the assessment and management of environmental noise. Secondly, the values of the Noise Depreciation Sensitivity Index (NDSI) were calculated. NDSI determines the percentage change in property prices per dB increase in noise levels. The distribution of unit prices of apartments was mapped relative to noise levels, and the relationships between the analyzed variables were assessed. Thirdly, linear correlations between the unit prices of apartments and noise levels were analyzed. The strength and direction of relationships between the analyzed parameters were determined based on Pearson’s correlation coefficient. In the last stage, the distribution of the unit prices of apartments was mapped by ordinary kriging, a geostatistical estimation method. The research hypothesis was confirmed by comparing the spatial distribution of traffic noise levels measured in stage 1 with the spatial distribution of apartment prices.
