广西南宁某地段全长5500m三级公路方案设计(含CAD图)(任务书,开题报告,外文翻译,计算说明书20000字,CAD图纸6张)
摘 要
本设计主要是广西南宁地区三级公路的设计。设计公路全长5500m，设计速度40km/h，双向双车道。本设计先整理了各种设计资料和依据，对沿线自然条件、设计技术标准和主要经济技术指标进行了研究。然后进行了路线设计，包括了平面设计纵断面设计，横断面设计、平纵组合设计和土石方计算与调配。接着又对路基进行了设计：布置路基横断面，并对路基的排水、防护进行了设计。接着又对路面进行了设计：对道路行车进行了轴载换算后设计了路面结构，并进行了应力验算。设计最后对桥梁涵洞进行了简单的设计。通过本次设计使我对专业知识加深了了解，为我以后的工作、学习提供了帮助。设计内容包括:选线与定线、平面设计、纵断面设计、横断面设计、土石方调配、路面结构设计、排水设计等。

ABSTRACT
This design mainly GuangXi Nanning area three highway design. Design of highway design speed of full-length 5635.990m, 30km / h, single lane. The design of first organize a variety of design data and the basis, by the natural conditions, the design of technical n is standards and main technical and economic indexes are studied. Then the route design, including graphic design, longitudinal design, cross-sectional design, longitudinal design and calculation and allocation. Then on the roadbed design: layout of subgrade cross section, and the subgrade drainage, protection of design. Then on the pavement to the design: road traffic axle load conversion after the design of the pavement structure, and the stress checking. Design of bridges and culverts in the simple design. Through this design enabled me to the professional knowledge to deepen understanding, for my future work, study offers to help.
Keywords: route design, design of subgrade, pavement design
