Preface

By improving the level of highway engineering survey and design, it can not only ensure the rationality of highway route, but also effectively reduce the occurrence of road traffic accidents. Due to the increasing scale of highway engineering construction in China, highway engineering survey and design work has attracted the attention of relevant departments. For Highway Survey and design personnel, the following principles should be observed:
      First, the design principle of respecting nature. In the process of Highway Survey and design, the survey and design personnel should seriously abide by the design principle of respecting nature and put the protection of ecological and natural environment in the first place. Because the highway engineering construction has a great impact on the natural ecological environment, which increases the difficulty of ecological environment restoration. Therefore, the highway survey and design personnel should abide by the principle of respecting the natural design, effectively investigate the topography of the area, and adopt a variety of design methods for design.
      Second, the principle of safety design. In the process of highway survey and design, the survey and design personnel should seriously abide by the principles of safety design, comprehensively consider various potential safety hazards, and take good measures to improve the safety of highway vehicles. By abiding by the principle of safety design, it can ensure that the highway survey and design scheme is more perfect, and effectively reduce the probability of highway traffic accidents.
         In addition, through the reasonable analysis of the existing problems and Countermeasures in highway survey and design, such as scientific design of highway route, comprehensive consideration of geological conditions along the highway, improvement of geological survey technology and so on, it can ensure the orderly progress of highway survey and design, and improve the implementation effect of highway survey and design scheme. Highway survey and design has a certain degree of difficulty, designers should continue to learn advanced knowledge, improve their professional skills, so as to promote the rapid development of China’s highway industry.

前 言

通过提升公路工程勘察设计水平，不仅能够保证公路路线的合理性，还能够有效减少道路交通安全事故的发生。由于我国公路工程建设规模的不断加大，公路工程勘察设计工作已经引起有关部门的重视，对于公路勘察设计人员来讲，要遵守以下原则：
        第一，尊重自然的设计原则。在公路勘察设计环节，勘察设计人员要认真遵守尊重自然的设计原则，将生态自然环境保护放在首位。因为公路工程建设施工对自然生态环境影响特别大，增加了生态环境的修复难度，因此，公路勘察设计人员要遵守尊重自然设计原则，对该地区的地形地貌进行有效勘察，采用多种设计方法进行设计。
        第二，安全设计原则。在公路勘察设计过程之中，勘察设计人员要认真遵守安全性设计原则，综合考虑各项安全隐患，并采取良好措施，提升公路车辆的安全性。通过遵守安全性设计原则，能够保证公路勘察设计方案更为完善，有效降低公路交通安全事故的发生概率。
        此外，通过对公路勘察设计中存在问题解决对策进行合理分析，例如科学设计公路路线、综合考虑公路沿线地质条件、完善地质勘察技术等等，能够保证公路勘察设计工作有序进行，提高公路勘察设计方案的实施效果。公路勘察设计具有一定难度，设计人员还要不断学习先进知识，提高自身的专业技能水平，进而推动我国公路事业的快速发展。
