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...

圆形钢筋混凝土桩局部破除后抗弯能力计算及应用

深基坑工程中常常出现围护桩成桩垂直度偏差以致侵入主体结构限界的现象，为保证后续主体结构尺寸符合要求，需要对侵限部位进行凿除，进而导致其抗弯承载能力下降。针对圆截面桩体局部凿除后的抗弯承载能力计算问题，基于二次逼近法，建立圆形钢筋混凝土桩局部破除后正截面抗弯承载能力计算方法，结合实际工程分析围护桩局部破除后对基坑围护结构体系的安全性影响。结果表明： 桩身局部破除后，纵向受力钢筋切断和桩身截面面积的减小将导致桩身正截面抗弯能力快速下降；依托工程中800 mm 的围护桩，凿除18 cm 厚度（含切断6根主筋）后，其正截面抗弯能力下降至原设计值的55%，剩余承载力已不能满足安全支护的要求，需进行加固处理。
