1956年中,我们测设了三条二级公路,由于我们对于高级公路的要求与其技术的复杂性认识不足,因而在工作中走了不少弯路。现将第六第八两个测量队在测设105线中所获得的几点体会,摘录如下,以供今后测设高级公路的研究参考。一、线型高级公路速度高、运量大,路线应力求直捷舒顺。路线的等级越高,线型越接近直线,在地形许可的条件下直线长度可不受限制。中小桥与河流正交及线路与铁路正交的婴要,只在不影响路线顺直的条件下方可考虑,平原区的定线如无正确的地图常因局部的移动, In 1956, we measured three Class 2 highways, and due to our lack of understanding of the demands of the highways and the complexity of their technologies, we made many detours in our work. Now the sixth eight eight two measurement team in measuring 105 lines obtained by the experience of several excerpts below, for future high-profile highway survey and design reference. First, the high-speed linear high-speed, large traffic, the route should be quick and easy. The higher the level of the route, the closer the line is to a straight line, and the length of the line can be unlimited under the conditions of the terrain. Small and medium-sized bridges and rivers and the orthogonal lines and infants to the railway, only under the conditions do not affect the straight line can be considered, the plains area alignment without a correct map often due to local movement,
