在推行汽车列车化的情况下,对道路修建标准的提高日益需要,有关这种技术标准问题,公路总局公路科学研究所正进行试验研究,尚未得出可靠的验证资料,目前各省进行大力改建公路所用标准亦不一致。兹参照交通部公路设计院对汽车列车化,对道路标准要求的初步意见及结合我区具体情况,提供有关公路修建技术标准的初步意见如下:一、有关路线的主要技术依据(Ⅰ)路线纵坡路线纵坡对行驶列车是最主要的关键性技术问题,我区多系山岭丘陵地带,原有公路坡度既陡,修建公路
In the case of the implementation of the automobile train, the improvement of road construction standards is increasingly needed. Regarding such technical standards, the Highway Science Research Institute of Highway Administration is carrying out experimental studies and no reliable verification data have been drawn yet. At present, every province has vigorously rebuilt the roads The standard used is also inconsistent. With reference to the Preliminary Opinions of the Highway Design Institute of the Ministry of Communications on the automobile train, the requirements of the road standards and the technical standards for road construction in light of the specific conditions of our region, the following are the primary opinions: I. Main Technical Basis of the Routes (Ⅰ) Slope course Longitudinal train on the train is the most important key technical issues, I District multi-ridge mountain hilly areas, the original road slope is steep, the construction of roads
