大广蒙冀界段公路构造物安全环保设计研究

Research on structure safety and environmental protection of Boundary of Inner Mongolia and Hebei section,Daqing- Guangzhou Highway

大庆-广州高速公路蒙冀界段公路主线和支线均采用高速公路标准,设计速度较高,隧道、互通立交多而复杂,安全环保问题突出,既有共性问题又有特殊问题,坡度、洞口、弃渣、防冻、互通顺接成为主要问题,因此,对交通工程及沿线设施提出更多要求。

Both the principal line and branch of Boundary of Inner Mongolia and Hebei section, Daqing - Guangzhou High- way adopted expressway standard, design speed is high, too many tunnel and complicated interchanges, safe environmental pro- tection problems is serious, there are both common problems and special problems, slope, hole, abandon slag, antifreeze and in- terflow connect become major problem, therefore, puts forward more requirements on traffic engineering and roadside facilities.
