道路勘察课程设计

1、公路勘测设计说明书一、课程设计的目的和任务公路勘测设计课程设计是公路与城市道路专业的实践课。本实践课的主要目的和任务是：（1）、设计文件中原始资料的查询、收集；（2）、掌握平面设计、纵断面设计、横断面设计中各种设计指标的选取，初步学 习各相关规范的查找及使用。二、课程设计的内容和要求公路勘测设计课程设计的内容：（1）按照地形地物的规定识别道路沿线 自然特征；（2）平面设计一一各种几何参数的选取；（3）纵断面设计一一主要指 标的选择；（4）横断面设计一一路幅布置及路拱坡度。由于路基路面工程没有单 独的课程设计，所以本设计还包含一部分路基路面的结构综合设计内容。公路勘测设计课程设计的内容：（1）通

2、过资料查阅和学习了解道路设计 的基本方法；（2）掌握平、纵、横设计之间的关系并学会运用，学会路基路面的 结构综合设计。三、设计资料道路等级：一级设计行车速度：100Km/h地形图：见图四、项目介绍邓王一级公路，里程桩号 K0 000mK3 3128.8475m，全长3128.847m。五、地形地貌该地区属冲积平原，地形开阔，地势起伏平缓，沿线河流、排灌沟渠交错， 农田水利设施完善，乡村道路网密集、区域内均为高产农田区。沿途小沟渠较多 可采用涵洞处理。拟建公路沿线地势总体较平坦，沿途多为农田。K1 +480m, K1+940m K2+420,K2+740,K2+76C和 K3+128.8475处

3、地势较低，需进 行高填方，路基采用搅拌桩处治。沿途小沟渠较多可采用涵洞处理。K0 + 5601, K1+940m K1+960m K2+42C和K2+820处要求横跨公路，可设置净空为6m的通道横跨。K1+60m处有一水塘，须进行填方，路基采用搅拌桩处治。六、道路所在地区的土壤、地质、水文资料、气候（1）土壤：本段内地层主要由第四系松散沉积层所组成，表层为素填土和粘性土。土质均一，呈硬塑一一半硬塑状。(2) 地质构造：该地段经历了历史上比较复杂的活动时期，其活动方式在不同的历史时期出现明显的多样化，整个地区无不良地质现象，工程地质良好。(3) 水文：该地区无大的河流，但区段内灌溉沟渠交错，经有

4、关勘探单位检测表明，沿 线沟渠水质良好。沿线有大量地表潜水，地下水一般埋深 0.52.5m,并随汛期 发生变化地下水表现为碳酸盐山丘区的岩溶水。气候本地区属暖湿带半湿润季风气候区， 海洋型与大陆型过度的气候特征较明显，气候温和，四季分明，雨量充沛，春秋季短，冬寒夏热，年内夏秋雨季降水的相对 集中，易出现暴雨造成涝灾，其余季节的降雨量偏少，气候区内的年平均气温13.7 ° C,以7、8月份最热，年平均最高气温19.4 ° C,历年的平均最底气温9.1 ° C,年平均最高气温39.9 ° C,历年的平均最高积雪深度20,最大冻土深度是33, 历年平均的无霜期

5、163.5天，气候区年内的平均降水量884.0，历年的最大年降 水量1358.0 , 710月份降水相对集中，区域内常年的主导风向为东北风，历年的平均风速为3.3，最大风速为16.8 , 8、9月份受台风影响区内空气湿度较大， 年平均相对湿度为70流右，最小相对湿度为65%最大相对湿度为85%七、不 良地质根据中国地震动参数区划图(GB18306-2001),线路经过区地震基本烈度7度，地震峰值加速度为 0.10g。八、交通量资料该路段交通量组成如下:车型总重前轴重后轴重后轴数前轴数交通量小汽车115200南京NJ-13053.615.338.3111200解放CA-10B80.2519.46
