Abstract
The detailed design specification introduced , firstly roads (60km/h) of the entire design process and the technical requirements for the construction outlined. Design process is divided into : the horizontal bar design sections, vertical section design, photographic design, to separate sections of the structure design, and road design and construction, structural budgeting. After calculation design, has been the main outcome of the design : graphic design line, vertical section design, photographic design, the design of retaining walls, culverts and small bridges design and linear curve corner table, roadbed design tables, the number of earth and stone tables, road widen table, the number of protective engineering table, the final number of works under a construction plan of budgeting.
Key words: firstly roads (60km/h)
内容提要
本设计说明书详细介绍了一级公路（60km/h）整个设计过程的情况，并对施工的技术要求进行了扼要说明。设计过程大概分为：路段的平面线形设计、纵断面设计、横断面设计，对部分路段的结构物进行单独设计，以及路面结构的设计和施工图的预算编制。经过计算设计，所得到基设计表、土石方数量表、路面加宽表，防护的设计成果主要有：路线平面设计图、纵断面设计图、横断面设计图，挡土墙设计图、涵洞及小桥设计图以及直线曲线转角表、路工程数量表，最后根据工程数量，进行了施工图的预算编制。
