一、概述对于高等级公路的测设工作,我们现还处于摸索起步阶段。高等级公路车速高、通过能力大,要求安全、舒适、经济、美观,这对设计的要求就更高了。在线形设计上,除了满足汽车行驶在力学上保证安全外,还要保证司机在视觉和心理上都有良好的安全感。路线应与周围地形、自然景观协调一致、融为一体,并尽量降低工程造价,有良好的环境效益和经济效益。为此,其关键是选出一条合理的平、纵线形。下面,就自己近几 I. Overview For high-grade highway survey and design work, we are still in the initial stages of exploration. High-speed high-speed road through the capacity of large, requiring safety, comfort, economy, beauty, which the design requirements even higher. In the linear design, in addition to meet the car to ensure the safety of mechanics, but also to ensure that drivers have a good sense of security, both visually and psychologically. The route should be in harmony with the surrounding topography and natural landscape, and be integrated as one. The project cost should be minimized with good environmental and economic benefits. To this end, the key is to choose a reasonable flat, vertical line. Below, I myself almost
