1.6、使用主要儀器設(shè)備
本工程使用ZHDV8雙頻GPS接收機(jī),儀器均由國(guó)家計(jì)量部門(mén)授權(quán)檢定單位進(jìn)行過(guò)鑒定,其結(jié)果滿(mǎn)足GPS規(guī)范規(guī)定與本工程精度要求,并在測(cè)量外業(yè)開(kāi)始前按規(guī)范要求對(duì)儀器相關(guān)項(xiàng)目進(jìn)行了常規(guī)檢驗(yàn),且檢驗(yàn)結(jié)果表明所用儀器設(shè)備性能穩(wěn)定、可靠。
二、控制測(cè)量
本次測(cè)量為高斯投影面為3°帶第36投影帶,中央子午線(xiàn)為108°00′00″,1954年西安坐標(biāo)系,1956年黃海高程系.2.1、GPS觀測(cè)技術(shù)要求(1)基線(xiàn)邊長(zhǎng)相對(duì)中誤差優(yōu)于
(10mm)2(5ppms)2
(式中s為基線(xiàn)長(zhǎng),單位Km)(2)有效觀測(cè)衛(wèi)星數(shù)≥6;
(3)時(shí)段中任一衛(wèi)星有效觀測(cè)時(shí)間≥60min(4)觀測(cè)衛(wèi)星高度角≥120(5)觀測(cè)時(shí)段1
(6)數(shù)據(jù)采樣間隔15秒;(7)PDOP值≤8
(8)天線(xiàn)高在觀測(cè)前、后各量測(cè)一次2.2、平差計(jì)算
GPS網(wǎng)基線(xiàn)解算采用商用基線(xiàn)解算軟件ZHD201*進(jìn)行,基線(xiàn)解算工作于觀測(cè)當(dāng)天晚上傳輸完數(shù)據(jù)后隨即完成,并及時(shí)組成閉合環(huán)、進(jìn)行三維無(wú)約束平差進(jìn)行檢驗(yàn)。解算出每個(gè)時(shí)段的合格基線(xiàn),組成同步環(huán)進(jìn)行檢驗(yàn)。檢驗(yàn)可知其組成的同步環(huán)閉合差均滿(mǎn)足要求。異步環(huán)閉合差是衡量GPS網(wǎng)外業(yè)觀測(cè)數(shù)據(jù)質(zhì)量最重要的指標(biāo),最后平差時(shí)為保證全網(wǎng)有良好的圖形結(jié)構(gòu)。本次觀測(cè)閉合環(huán),其中異步環(huán)閉合差的最大值為1.5ppm可以看出:其異步環(huán)閉合差非常小,表明GPS網(wǎng)觀測(cè)數(shù)據(jù)質(zhì)量?jī)?yōu)良,觀測(cè)中不含粗差觀測(cè)值,所選基線(xiàn)可供內(nèi)業(yè)平差計(jì)算使用。2.3、GPS網(wǎng)平差
平差計(jì)算采用ZHD-201*軟件,利用2個(gè)已知點(diǎn)進(jìn)行約束平差。2.4精度評(píng)定
為了對(duì)GPS網(wǎng)內(nèi)部符合精度進(jìn)行檢驗(yàn)評(píng)估,以及檢測(cè)和剔除粗差觀測(cè)值,先進(jìn)行WGS-84坐標(biāo)系下的三維無(wú)約束平差。然后進(jìn)行約束平差,從網(wǎng)平差結(jié)果可知,未發(fā)現(xiàn)其粗差觀測(cè)值,基線(xiàn)向量改正數(shù)較小且服從正態(tài)分布,邊長(zhǎng)中誤差分布正常,最弱邊相對(duì)中誤差1/124520>1/40000、最弱點(diǎn)點(diǎn)位中誤差15mm<50mm值均比較小,表明該網(wǎng)達(dá)到了較高的精度。
三、質(zhì)量檢查及驗(yàn)收
質(zhì)量,作為一個(gè)工程項(xiàng)目的靈魂,它決定著一個(gè)工程的成敗。在質(zhì)量體系上我們執(zhí)行“三查二審”的原則。所為三查:自查、互查、專(zhuān)業(yè)查。二審:項(xiàng)目負(fù)責(zé)人審查、測(cè)量部審核提交最終成果。對(duì)本工程而言所有基礎(chǔ)控制資料都已通過(guò)內(nèi)外業(yè)完成200的檢查。測(cè)量部審核終成果提交正式成果報(bào)告。
本項(xiàng)目驗(yàn)收工作有監(jiān)理部組織,有甲方領(lǐng)導(dǎo)、煤礦測(cè)量站代表、監(jiān)理部、施工單位橫山縣煤炭規(guī)劃開(kāi)采測(cè)繪中心協(xié)助配合於4月19日對(duì)測(cè)量方法、使用設(shè)備、工作進(jìn)度等進(jìn)行了全面的論證和檢查。
四、結(jié)論
橫山縣高興莊煤礦近井點(diǎn)測(cè)量應(yīng)用了測(cè)繪高端技術(shù)使用了高精度測(cè)量?jī)x器GPS(ZHD-V8),滿(mǎn)足工程質(zhì)量保證了工程進(jìn)度。

6、地面平面控制測(cè)量
根據(jù)工程要求,本次首級(jí)平面控制網(wǎng)以E級(jí)GPS網(wǎng)來(lái)布設(shè),高程控制以E級(jí)GPS測(cè)量。
(1)選點(diǎn)埋石
GPS點(diǎn)周?chē)鷳?yīng)視野開(kāi)闊,視場(chǎng)內(nèi)障礙物的高度不宜超過(guò)15°,點(diǎn)間距以100~500米之間為宜;距離強(qiáng)發(fā)射源不小于200m,高壓線(xiàn)不小于50m;避開(kāi)強(qiáng)烈反射衛(wèi)星信號(hào)的大型建筑物。所有點(diǎn)的埋設(shè)均應(yīng)有利于長(zhǎng)期保存,始終應(yīng)以看到井口面中心點(diǎn)為原則,相鄰點(diǎn)間須通視良好,有利于聯(lián)系測(cè)量。
控制點(diǎn)是本次測(cè)量中十分重要的起算依據(jù),一定要埋設(shè)好,保護(hù)好。標(biāo)石采用預(yù)制混凝土標(biāo)石,標(biāo)石上底200mm×200mm下底400mm×40mm高600mm。點(diǎn)標(biāo)芯采用Φ14mm,長(zhǎng)200mm帶鉤鋼筋,上鋸“十”字。混凝土選用C20號(hào),表面平滑,標(biāo)芯露出標(biāo)石面5mm,標(biāo)芯要安置在標(biāo)石中心。挖好坑后,下方大于20cm的現(xiàn)澆混凝土澆筑,中間夯實(shí)回填土,上面用厚度≥5cm,寬度≥10cm的

(2)控制網(wǎng)施測(cè)
以西掩(D級(jí))、尾氣檢驗(yàn)站(D級(jí))、核桃洼(D級(jí))為基點(diǎn),充分利用原有已知控制點(diǎn)布設(shè)成GPS三角網(wǎng),采用邊連式的布網(wǎng)方式,相鄰點(diǎn)間最大距離≤10km、最小距離≥100m;野外觀測(cè)采用五臺(tái)套NGS9600單頻GPS接收機(jī),靜態(tài)相對(duì)定位測(cè)量方法,根據(jù)《全球定位系統(tǒng)(GPS)測(cè)量規(guī)范》(GB201*)的有關(guān)規(guī)程、規(guī)范作業(yè),衛(wèi)星高度角≥15°、有效衛(wèi)星觀測(cè)總數(shù)≥4顆、有效觀測(cè)時(shí)段≥60分鐘、數(shù)據(jù)采樣間隔20min、點(diǎn)位幾何圖形強(qiáng)度因子PDOP≤6;平面為1980年西安坐標(biāo)系,6度帶高斯投影(中央子午線(xiàn)111°),Y值已加500km,高程為1985年國(guó)家高程基準(zhǔn)。
采用南方GPS數(shù)據(jù)處理軟件進(jìn)行數(shù)據(jù)解算1、無(wú)約束平差
GPS網(wǎng)無(wú)約束平差是在WGS-84坐標(biāo)系下的平差,處理由于多余觀測(cè)誤差而引起的網(wǎng)內(nèi)不符值,以反映GPS網(wǎng)的內(nèi)部符合精度,平差過(guò)程中沒(méi)有發(fā)現(xiàn)粗差現(xiàn)象,平差結(jié)果為:最大點(diǎn)位中誤差:
Mxy=0.018(米)2、平面
以西掩(D級(jí))、尾氣檢驗(yàn)站(D級(jí))、核桃洼(D級(jí))控制點(diǎn)作為基準(zhǔn)點(diǎn)對(duì)GPS網(wǎng)進(jìn)行1980年西安坐標(biāo)系二維約束平差。
最大點(diǎn)位中誤差:M=0.043466(米)最弱邊相對(duì)中誤差:M/S=1:610003、高程(約束平差)
以西掩(D級(jí))、尾氣檢驗(yàn)站(D級(jí))、核桃洼(D級(jí))控制點(diǎn)高程作為起算數(shù)據(jù),對(duì)GPS網(wǎng)進(jìn)行1985國(guó)家高程基準(zhǔn)的高程約束平差,擬合大地水準(zhǔn)面,推算GPS網(wǎng)點(diǎn)的高程。

為了使得井上、下采用統(tǒng)一的平面坐標(biāo)系和高程系統(tǒng),應(yīng)進(jìn)行聯(lián)系測(cè)量。聯(lián)系測(cè)量根據(jù)工程特點(diǎn)進(jìn)行一井單絲投點(diǎn),陀螺全站儀定向的方法進(jìn)行。投點(diǎn)時(shí)用
的鋼絲應(yīng)盡可能采用小直徑的高強(qiáng)度鋼絲,但必須保證足夠的抗拉強(qiáng)度。在垂線(xiàn)下放后,嚴(yán)格檢查重砣與桶壁、桶底之間及垂線(xiàn)與井壁、井筒設(shè)備之間有無(wú)接觸之處。當(dāng)確認(rèn)無(wú)接觸后,在鋼絲完全穩(wěn)定后井上下同步進(jìn)行觀測(cè)。擺動(dòng)垂線(xiàn)位置采用標(biāo)尺法確定擺動(dòng)垂線(xiàn)位置,按垂線(xiàn)的最大擺幅在標(biāo)尺上的位置,連續(xù)讀取13次以上(次數(shù)為奇數(shù))的讀數(shù),并取左、右讀數(shù)平均值的中數(shù)作為垂線(xiàn)在標(biāo)尺上的穩(wěn)定位置。按上述方法連續(xù)進(jìn)行兩次,兩次結(jié)果的互差不超過(guò)1mm,取其平均值作為最終結(jié)果。
鋼絲至儀器間的長(zhǎng)度采用鋼尺丈量方法進(jìn)行,在垂線(xiàn)穩(wěn)定情況下應(yīng)用鋼尺以不同起點(diǎn)丈量六次,取其平均值作為丈量結(jié)果。同一邊長(zhǎng)各次觀測(cè)值互差不大于2mm。
