毕设基本摘要
摘 要
根据设计任务书提供的设计资料和设计要求以及交通部颁发的标准和规范对济宁至祁门高速公路第二标段进行路基路面综合设计。
此次设计主要内容包括：路线设计、路基设计、涵洞设计、路面设计，专题研究。根据提供的路线原始资料，考虑土石方填挖平衡、最大纵坡、最小纵坡、坡长、高程控制点等因素进行纵断面设计,由此结合平面图进行横断面设计。根据设计段内的地形状况，设置了排水沟、急流槽、圆管涵等排水设施。高填路堤路段利用表解法和解析法进行了稳定性验算。同时，进行防护工程设计,采用植草皮、砼预制块等多种形式进行边坡防护。进行了沥青混凝土路面的设计和水泥混凝土路面的设计，由给定的交通量等条件，按照路面结构组合设计的原则，选用不同路面结构层厚度和材料进行结构设计验算,并进行了方案比选。

ABSTRACT
According to the design information, demands of the design task instrument, the technical standards and specifications for freeway design published by the Ministry of Communications of China, the comprehensive design of freeway subgrade and pavement from the second section has been carried out based on the data of Jiqi freeway.
Our prime contents of the design project includes freeway route design, subgrade design, culvert design, pavement design and special study. According to route firsthand information that is offered , we must keep the balance between the diging and filling out, maximun vertical slope, minimum vertical slope, the length of slope, high control point, etc. During designing the vertical section and combining the plane figure ,we design the cross section. According to the terrain conditions of the design segment, set up drainage system which includes side ditch, intercepting ditch, etc. In high embankment highway section, make use of table solution and analytical to follow the checking stability calculation. Meanwhile, do protect engineering design, adopt plant turf to protect the slope, etc. Do the design which has carried on the asphalt concrete road surface and design of the cement concrete road surface by giving volume of traffic definitely terms, according to the design principle of the road surface structure, select for different road surface structure layers of thickness and material then carry on structural design checking computations, and do scheme comparison.
Keywords：freeway; subgrade design; culvert design; pavement design; comprehensive design
