高架桥基础承台开挖引起的路面差异沉降控制方法研究

高架桥基础承台施工时需开挖基坑,回填后新路基在车辆荷载作用下将产生较大的沉降,故造成新老路基上部路面的差异沉降。该文采用有限差分软件FLAC3D分析研究不同的土工格栅层数、格栅模量、格栅位置、回填材料以及基坑开挖方式对减小路面差异沉降的效果。计算结果表明:格栅层数越多对减小差异沉降的效果越好,并且随着格栅层数的增加,格栅加筋效果减弱。增加格栅模量也可减小路面不均匀沉降,且格栅铺设的3个位置都有作用,其中铺设在面层与基层交界处效果最好。回填材料选择二灰土可以明显减小新老路基的差异沉降,故采用类似二灰土等坚硬的回填材料具有很好的效果。基坑开挖采用放坡开挖的方式,对减小沉降与差异沉降方面的效果优于台阶开挖。

The perception of Bus Rapid Transit: a passenger survey from Beijing Southern Axis BRT Line 1

Bus Rapid Transit (BRT) has emerged as a cost-effective transport system for urban mobility. As a relatively new form of Mass Transit, its ability to provide a high-quality transport service and potential to stimulate land development remain largely unexplored. This study intends to investigate the public attitude towards BRT services, as well as respondents’ perception of living near BRT stations, using the Beijing Southern Axis BRT system as a case study. A data-set of responses to 525 questionnaires were assembled and analysed using a combination of statistical techniques. The results show that BRT has gained great popularity among passengers, and brought about a positive impact on the attractiveness of residential property. The data identify that the majority of passengers are work-related commuters and use BRT more than once a day. The captive users have a higher satisfaction than choice users with respect to reliability, comfort & cleanliness and overall satisfaction with the BRT service. It is argued that the BRT has significantly improved the attractiveness of residential property along the BRT corridor.     

Experimental research on the mechanical properties of gypsum breccia with different water content

This paper deals with the influence of water content on the mechanical properties of gypsum breccia with different initial water contents. The experimental research was taken on the GDS (geotechnical digital systems) tri-axial experiment system by strain rate control. The mechanical properties,including stress-strain curves,peak deviator stress,relative residual strength,elastic modulus,Poisson's ratio,angle of internal friction and cohesion of gypsum breccia,were studied by experiment. The results showed t...
