Single Slope Surface Compartmentation Cingulum Concrete Exploitation Apply And Research In Expressway

In this thesis, for researching the traffic safety device—concrete guard fence ofthe median separator on the single face of slope of highway, we countered thepractical situation of GUILIN-LIUZHOU freeway,exploited and utilized this kind ofthe guard fence by linking up with the recent research in USA. According todynamics, engineering theory of structure etc., we fixed on the structure parameterabout this fence's strength, rigidity, height and form of inside slope. Meanwhile,we tested the capability of this guard fence adopting international common practice:experimental technology of auto collision. Furthermore, via the applications of theguard fence in the GUILIN-LIUZHOU freeway project, we improved this kind offence's feasibility, security and economy in reality. In addition to accelerating theprocess of concrete guard fence optimization which can make this technology to beadapted for the practical situation in China, our research will provide a basis for theformulating and modification of relevant rules, and then lay the foundation of thefence's popularization in the future.
