1、贵阳市环城高速公路K6+600~K8+000段路基路面综合设计摘要本设计是贵阳市环城高速公路K6+600~K8+000段路基路面综合设计路基路面综合设计。本设计路段全长1.4km,采用高速公路设计标准,设计时速100km/h,双向四车道,路基宽26m,其中行车道宽2×7.5m,中央分隔带宽2m,路缘带宽0.75m,硬路肩宽3m,土路肩宽0.75m。本设计内容包括主线平面设计,路线纵断面设计,路基横断面设计,边坡稳定性分析,挡土墙设计,边坡防护设计,路基路面排水设计,路面结构设计几个方面。路线设计中严格遵照行业规范,所有线型指标均满足高速公路最低线型指标要求,并综合考虑了经济性要求。
2、路基横断面设计中,选择最高边坡进行边坡稳定性分析,并在高边坡路段设置俯斜式路堤挡墙和护脚墙。排水设计中,对排水沟、边沟尺寸进行了水力计算。水泥路面和沥青路面设计中,两种路面分干燥和中湿两种状态各三种备选方案,通过比选,各选出了一种最优方案。本设计应用了纬地等软件。完成了英文文献《重塑膨胀粘土掺合石灰、氯化钙和稻壳灰的工程特性》的翻译。本计算书对各项设计内容进行了全面叙述。关键词:高速公路;路基路面;设计第6页共67页K6+600~K8+000SECTIONOFAROUNDTHECITYEXPRESSWAYINGUIYANGCITYCOMPREHENSIVEDESIGNOFSUBGR
