施工方案-施工測量平面控制網(wǎng)方案

che施工測量平面（高程）控制網(wǎng)方案（成果）一、概述1、工程概況秭歸縣九里移民安置小區(qū)功能完善項目共有5條道路系城市道路綜合改造。各條道路分別為：九里二路全長195米，紅線寬26米，車行道寬15米；建東大道全長764.55米，紅線寬32米，車行道寬22.5米；迎賓路全長1940米，九里二路至陡茅路紅線寬13米，陡茅路至楊貴店橋頭紅線寬15米，楊貴店橋頭至止點紅線寬18米。陡茅路全長370米，紅線寬18米，車行道12米；二圣路全長151.39米。五條道路總長3421米。2、設計提供測量點位根據(jù)建設單位按設計人提供的測量控制點為GPS-E級點共7個，其點號分別為：GPS1、GPS3、GPS4、GPS8、GPS9、GPS10、GPS11。二、測量方案測量現(xiàn)有資料平面坐標資料：按照業(yè)主提供的設計人移交的GPS控制點，因各點位之間有部分不能相互通視，施工過程無法進行，所以按照現(xiàn)場僅有通視條件，將首尾已知點GPS1、GPS8、GPS10進行了聯(lián)測，并按照施工要求在中間各施工段進行了加密，其加密點編號分別為：JM1、JM2、JM3、JM4、JM5、JM6、JM7、JM8、JM9、JM10、JM11。高程資料：按照建設單位提供的設計人移交的GPS-E級點，選擇GPS8為基準點，進行閉合和附合測量。cheche測量依據(jù)施工圖紙：a、建東大道路線平面圖、路線縱斷面圖及直線、曲線及轉角表、縱坡、豎曲線表；b、九里二路路線平面圖、路線縱斷面圖及直線曲線轉角表、縱坡、豎曲線表；c、迎賓路路線平面圖、路線縱斷面圖及直線、曲線及轉角表、縱坡、豎曲線表；d、陡茅路路線平面圖、路線縱斷面圖及直線、曲線及轉角表、縱坡、豎曲線表；e、二圣路路線平面圖、路線斷面圖及直線、曲線及轉角表、豎曲線表。規(guī)范依據(jù)：a、《城鎮(zhèn)道路工程施工與質量驗收規(guī)范》(CJJ1—2008),該規(guī)范中相關測量章節(jié)內容。平面控制測量按照《城鎮(zhèn)道路工程施工與質量驗收規(guī)范》(CJJ1—2008)5.2.6導線測量之規(guī)定，進行布點測量。城鎮(zhèn)道路工程施工首級控制(交樁點)測量、復核的主要技術指標如下表，經(jīng)實測數(shù)據(jù)進行平差，其結果導線全長相對閉合差：k=fs/8=1/31157,測量成果詳見后附件A。導線測量的主要技術指標 表5.2.6—1等級導線長度(km)平均邊長(km)測角中誤差(”)測距中誤差(mm)測回數(shù)2”級儀器方位角閉合差(”)導線全長相對閉合差備注一級40.551/30000210^n<1/15000二級2.40.2581/14000116^n<1/10000三級1.20.1121/7000124^n<1/50004、 高程控制測量按照由建設單位提供的GPS8點黃海高程點為基準點，分兩個布點方案，方案一：由GPS8點開始沿陡茅路至迎賓路交叉路口至九里二cheche路再至建東大道最終閉合至GPS8點，為滿足施工過程需要，方案一沿途共加密25個永久水準點，基本能保證施工過程中不被破壞；方案二由GPS8沿陡茅路至迎賓路向東至楊貴店再至二圣路、福利院門口終點，為滿足施工需要沿途加密21個永久水準點，能保證施工過程中不被破壞，直至竣工驗收均能使用該水準點。按照方案一和方案二現(xiàn)場實測其測量成果詳見附件二。高程控制按照《城鎮(zhèn)道路工程施工與質量驗收規(guī)范》（CJJ1一2008）,5.4.8、5.4.9城鎮(zhèn)道路高程控制之規(guī)定，進行兩測回實地測量，其測量成果見后附件B。5、測量設備測量儀器：平面控制測量儀器采用：國產廣州中海達測繪有限公司生產的全站儀，儀器其主要技術參數(shù)，測角精度：2〃，測距精度：2mm+2PPm。水準測量儀器：采用日本拓普康AT-B4,精度：±2mm/一公里往返誤差。三、坐標和高程系統(tǒng)本次測量系統(tǒng)：平面坐標系統(tǒng)采用1954年北京坐標系；高程基準采用國家水準黃海高程，依據(jù)由建設單位依據(jù)武漢衡通公路勘察設計院成果提供。四、測量控制點（平面、高程）成果本次測量成果共分兩個系統(tǒng)，平面坐標控制和高程控制系統(tǒng)，其實測數(shù)據(jù)，詳見本附件A、附后件B：A、平面控制測量成果表；B、高程控制測量成果表。che
