随着我国经济社会的发展,我国的教育事业得到了十足的发展,但是,在快速发展过程中还存在诸多问题需要我们去解决,如教学理念落后、教学方式落后等,近些年来,在国家教育部门的引导下,对我国各阶段的教育教学进行了一次深化改革,其中教学方法作为教学改革的重点与核心,其改革的好坏将直接影响整个国民教育水平的提高。俗话说的好,兴趣是最好的教师,所以,在课程改革不断深化的背景下,只有以学生的兴趣为出发点,才能更好更加有效的开展教学活动,才能提高学生对知识学习的积极性。本文今天就是基于此背景下对兴趣教学法在初中体育教学活动中的应用进行研究。 相似文献

2006年7月初,我避开了喧嚣的城市和酷暑的袭扰,又一次前往阿勒泰地区,准备航空拍摄福海辖区。从乌鲁木齐出发,沿着准噶尔盆地西缘的217国道向北行驶,途经和布克赛尔伊克乌图布拉格牧场,便转入318省道径直向福海县方向驶去。转眼间,公路两侧,绿草如茵,这和几小时前的砾漠地貌形成了强烈的反差,此时,空气中也散发着植被特有的芳香,同时,也享受着古尔班通古特沙漠北缘尽头乌伦古湖温暖湿润气候带来的凉爽。 相似文献

Two detailed bathymetric surveys document the effects of increased turbulence due to jet-propelled ferries and other ship traffic in Göteborg Harbour. Sedimentation is enhanced in areas where the water stratification is disturbed by harbour design and ship traffic. However, accumulation is dependent on bottom conditions, and erosion is prevalent in areas with heavy ship traffic, especially at turning sites. A geostatistical analysis of spatial bathymetric data indicates greater variability but a longer range of dependence between sites within areas of accumulation in comparison with those characterised by erosion or mixed erosion and accumulation. Changes in the geostatistical relationships induced by directing the comparison of sites along or across the channel are also possible to interpret in connection with the sedimentation conditions. Bathymetric variations, mineralogical trends, and contaminant changes support the interpretation of high bottom sediment mobility and the focusing of accumulation and erosion in specific areas. 相似文献

Due to increasing motorization, construction of flyovers and growth in transport network, the noise level has exceeded the prescribed limits in many Indian cities. The health implications of high noise levels are being identified as hypertension, sleeplessness, mental stress, etc. Due to this adverse effect of noise level, it is essential to assess the impact of traffic noise on residents and road users. This research is an effort to quantify and analyze the traffic noise emissions along bus rapid transit corridor in Delhi. Field measurements were carried out to understand and assess various aspects of the impact of bus rapid transit system corridor on land use and social lives of residents and road users. The present analysis presents the comparison between observed and predicted noise level at selected corridors and also describes the mitigatory measures to overcome such type of traffic noise pollution through design of noise barrier along the road and motivate people towards the use of public transport system. 相似文献

车辆动荷载是引起路面损坏的最主要原因。目前国内外相关研究多集中于单一车辆对路面结构所产生的动荷载,实际上路面结构所承受的是车流荷载,而且车流在行驶过程中各车辆的车速和车辆之间的距离会产生变化,但关于这方面的研究甚少。针对这一工程实际问题,采用微观交通流模型中的跟车模型来模拟车流行驶过程中各车辆的速度以及它们之间车距的变化,车辆振动模型采用1/4车身结构的两自由度模型,并根据国家标准GB7031-86[1]规定生成路面轮廓的时域信号。最后分析了某水泥混凝土路面在生成的车流荷载作用下的动力响应,为研究车流荷载作用下路面结构动力响应提供了基础性成果。 相似文献

This study applies artificial neural network (ANN) for the determination of optimized height of a highway noise barrier. Field measurements were carried out to collect traffic volume, vehicle speed, noise level, and site geometry data. Barrier height was varied from 2 to 5 m in increments of 0.1 m for each measured data set to generate theoretical data for network design. Barrier attenuation was calculated for each height increment using Federal Highway Administration model. For neural network design purpose, classified traffic volume, corresponding traffic speed, and barrier attenuation data have been taken as input parameters, while barrier height was considered as output. ANNs with different architectures were trained, cross validated, and tested using this theoretical data. Results indicate that ANN can be useful to determine the height of noise barrier accurately, which can effectively achieve the desired noise level reduction, for a given set of traffic volume, vehicular speed, highway geometry, and site conditions. 相似文献

To stabilise the tunnel faces and slopes in soft clay for the Airport Link construction in Australia, fracture grouting and glass fibre-reinforced plastic (GFRP) soil nails are proposed for the soil improvement as well as ease of handling. The compensation caused by the fracture grouting and the gain in strength due to consolidation as well as the geonail have stabilised the soft clay during construction. Only a small amount of ground settlement during soft clay box-jacking operation is generated so that the railway traffic above the embankment can be maintained without interference. The design method of the fracture grouting ground improvement study for this difficult project is discussed in this paper. Extensive laboratory and field tests were employed to verify the design assumptions and to fine-tune the ground improvement studies. The success of this project in poor ground conditions results from combined efforts of extensive field tests, an improved ground improvement design method and a realistic numerical analysis to assess the unstable/highly stressed zones for the placement of soil reinforcement. 相似文献
