道路勘察課程設計

1、公路勘測設計說明書一、課程設計的目的和任務公路勘測設計課程設計是公路與城市道路專業(yè)的實踐課。本實踐課的主要目的和任務是：（1）、設計文件中原始資料的查詢、收集；（2）、掌握平面設計、縱斷面設計、橫斷面設計中各種設計指標的選取，初步學 習各相關規(guī)范的查找及使用。二、課程設計的內容和要求公路勘測設計課程設計的內容：（1）按照地形地物的規(guī)定識別道路沿線 自然特征；（2）平面設計一一各種幾何參數(shù)的選??；（3）縱斷面設計一一主要指 標的選擇；（4）橫斷面設計一一路幅布置及路拱坡度。由于路基路面工程沒有單 獨的課程設計，所以本設計還包含一部分路基路面的結構綜合設計內容。公路勘測設計課程設計的內容：（1）通

2、過資料查閱和學習了解道路設計 的基本方法；（2）掌握平、縱、橫設計之間的關系并學會運用，學會路基路面的 結構綜合設計。三、設計資料道路等級：一級設計行車速度：100Km/h地形圖：見圖四、項目介紹鄧王一級公路，里程樁號 K0 000mK3 3128.8475m，全長3128.847m。五、地形地貌該地區(qū)屬沖積平原，地形開闊，地勢起伏平緩，沿線河流、排灌溝渠交錯， 農田水利設施完善，鄉(xiāng)村道路網(wǎng)密集、區(qū)域內均為高產(chǎn)農田區(qū)。沿途小溝渠較多 可采用涵洞處理。擬建公路沿線地勢總體較平坦，沿途多為農田。K1 +480m, K1+940m K2+420,K2+740,K2+76C和 K3+128.8475處

3、地勢較低，需進 行高填方，路基采用攪拌樁處治。沿途小溝渠較多可采用涵洞處理。K0 + 5601, K1+940m K1+960m K2+42C和K2+820處要求橫跨公路，可設置凈空為6m的通道橫跨。K1+60m處有一水塘，須進行填方，路基采用攪拌樁處治。六、道路所在地區(qū)的土壤、地質、水文資料、氣候（1）土壤：本段內地層主要由第四系松散沉積層所組成，表層為素填土和粘性土。土質均一，呈硬塑一一半硬塑狀。(2) 地質構造：該地段經(jīng)歷了歷史上比較復雜的活動時期，其活動方式在不同的歷史時期出現(xiàn)明顯的多樣化，整個地區(qū)無不良地質現(xiàn)象，工程地質良好。(3) 水文：該地區(qū)無大的河流，但區(qū)段內灌溉溝渠交錯，經(jīng)有

4、關勘探單位檢測表明，沿 線溝渠水質良好。沿線有大量地表潛水，地下水一般埋深 0.52.5m,并隨汛期 發(fā)生變化地下水表現(xiàn)為碳酸鹽山丘區(qū)的巖溶水。氣候本地區(qū)屬暖濕帶半濕潤季風氣候區(qū)， 海洋型與大陸型過度的氣候特征較明顯，氣候溫和，四季分明，雨量充沛，春秋季短，冬寒夏熱，年內夏秋雨季降水的相對 集中，易出現(xiàn)暴雨造成澇災，其余季節(jié)的降雨量偏少，氣候區(qū)內的年平均氣溫13.7 ° C,以7、8月份最熱，年平均最高氣溫19.4 ° C,歷年的平均最底氣溫9.1 ° C,年平均最高氣溫39.9 ° C,歷年的平均最高積雪深度20,最大凍土深度是33, 歷年平均的無霜期

5、163.5天，氣候區(qū)年內的平均降水量884.0，歷年的最大年降 水量1358.0 , 710月份降水相對集中，區(qū)域內常年的主導風向為東北風，歷年的平均風速為3.3，最大風速為16.8 , 8、9月份受臺風影響區(qū)內空氣濕度較大， 年平均相對濕度為70流右，最小相對濕度為65%最大相對濕度為85%七、不 良地質根據(jù)中國地震動參數(shù)區(qū)劃圖(GB18306-2001),線路經(jīng)過區(qū)地震基本烈度7度，地震峰值加速度為 0.10g。八、交通量資料該路段交通量組成如下:車型總重前軸重后軸重后軸數(shù)前軸數(shù)交通量小汽車115200南京NJ-13053.615.338.3111200解放CA-10B80.2519.46
