1、哈尔滨理工大学学士学位论文宁安市石岩镇至江东林场A标段一级公路设计摘要此次毕业设计是对宁安市石岩镇至江东林场段重丘陵地区的一级公路的方案设计,首先从选线、布线开始,依次进行平面设计、纵断面设计、横断面的设计,通过平纵横结合和交通量以及设计时速,得出路线的超高,从建设的经济性和合理性方面进行方案的比选,最后根据实际情况选出最合适的方案,尽量采取少挖填,减少工程量。然后进行公路挡土墙设计、路基路面设计。挡土墙主要进行主动土压力验算、稳定性验算(包括抗倾覆稳定性和抗滑移稳定性)以及地基承载力的验算,从而确保挡土墙安全稳定;路基路面
2、设计主要对道路横断面的设计以及路面结构层的设计和计算,横断面设计主要根据交通量和时速以及边坡坡度,同时保证排水的前提下进行设计;结构层设计是根据自然区划选择路面材料,同时也要对路面的强度、刚度和稳定性进行验算,以确保一级公路,在结构层方面的稳定性,该设计同时也给出了平纵横设计相关的表格跟图纸以及挖填的土石方调配表和路线的三维模拟图等内容。关键词公路设计;一级公路;仰斜式挡土墙;沥青路面-I-哈尔滨理工大学学士学位论文NinganrocktowntojiangdongforestbidAlevelofhighwaydesign
