某一级公路（K15+300~K16+700）路基路面综合设计

摘 要

利用所学知识及公路最新设计规范，对某一级公路进行路基路面综合设计。在设计中，本着安全，经济，实用，可靠的原则，充分考虑公路与周围环境的和谐统一，全面分析此一级公路路基路面设计中出现的所有问题。从填挖平衡和行车安全等方面着手，进行路线纵断面设计；通过沥青、水泥混凝土路面结构设计及方案的比选，最终选用一般沥青混凝土路面结构；根据地形图及周边环境的需要，精心设计桥涵等构造物，使之即不破坏原来的自然环境，又要满足一定的要求；针对不同路段的路基填挖高度，分别采用植物防护或工程防护，或者二者结合；借鉴当前施工新工艺，新技术，采用新材料，用于设计中。

关键词：一级公路，路基路面，桥涵构造物，防护，综合设计。

某一级公路（K15+300~K16+700）路基路面综合设计

Abstract

Taking advantage of the latest highway conformity, design a grade 1 highway in subgrade and pavement comprehensively. In designing, considering secure-economic-practical idea and the harmony unify of the freeway with surroundings, analyses all aspects which include subgrades and pavements.

Thinking over the balance between excavating and filling and the facilities of road, plan the sections.

Comparing to the pavement structure of asphalt cement and concrete, select the pavement structure of cement and concrete.

According terrain map, conceive the bridges and culverts carefully without destructing normal environment. In accordance with the heights of excavating and filling from different subgrades’ structures; adopt the vegetable defection and projectcal defection or the combination of them.

Referring to current new construct method, new technique and the newest material are used in the design.

Keyword: grade 1 highway subgrade and pavement
