武汉伽利勘察设计有限责任公司承担了福银高速十天联络线定测任务。该项目：主线60KM，互通4处，服务区1处，桥梁与隧道较多。此联络线地处湖北西北部，属鄂西北中山低山区。区域山丘顶部浑圆，局部由于较强烈的切割而显陡峻。沿线沟谷纵横，地形起伏较大，一般相对高差40400米，所经区域海拔在150600米之间，属于山岭重丘地形。由于封山育林，山上林木高大茂密，且夹杂大量荆棘，以及其他灌木，给定测带来很大不便。时值八、九月份，山中有害昆虫奇多，恰逢山区雨水季节，时有阵雨，山涧涨水，给测量工作带来很大困难。2 自检依据2.1勘测规范根据2007年7月1日新颁布的公路勘测规范（JTJ C10-2007）和公路勘测细则(JTG/T C10-2007)以及其他相关测量规范，检查要求如下：1、中桩平面桩位精度公路等级中桩位置中误差(cm)桩位检测之差（cm）平原、微丘重丘、山岭平原、微丘重丘、山岭高速、一、二级公路5101020三级及以下公路101520302、中桩高程测量精度公路等级闭合差（mm）两次测量之差（cm）高速、一、二级公路30L5三级及三级以下公路50L103、横断面检测互差限差公路等级距离（m）高差（m）高速、一、二级公路L/100+0.1h/100+L/200+0.1三级及三级以下公路L/50+0.1h/50+L/100+0.1地形图测量，依据公路勘测规范的相关规定，对地物点数据的采集精度要求如下：4、图上地物点的点位中误差重要地物（mm）一般地物（mm）水下地物（mm）1：5001：10001：20000.60.82.01.21.0表2等高线插值的高程中误差地形类别平原微丘重丘山岭水下高程中误差（1/3）Hd（1/2）Hd（2/3）HdHd1.2Hd表3地形图上高程注记点的间距比例尺1:5001:10001:20001:5000高程点注记间距153050100基本等高距为0.5m时，高程点注记应注到0.01m；基本等高距大于0.5m时，可注记至0.1m。2.2 定测要求1、中桩敷设与高程测量坐标系与路线控制网坐标系相同，线路控制测量成果为第三勘测设计室提供。 2、洞口前、后各30米，中桩按5米敷设。横断面左、右各宽60-100米。 3、线路中桩按20米敷设，在路线应设加桩的位置根据规范要求确定。 4、高程测量采用三角高程，其精度满足公路勘测规范（JTG C10-2007）的要求。 5、断面成果整理设计室要求的格式。 6、绘图软件为南方CASS6.1。3成果检测3.1自检成果10个测量工作组在外业测量工作结束后，即组织了相关人员对外业测量成果进行自检工作，抽查一定数量的中线与断面数据展绘到地图上。到实地进行地形查看、比对以及对中线点进行测量对比的自我检查。抽查量达到30%以上。3.3.2互检成果1、互检组对已放中桩重新测量坐标与高程，和原成果进行比较，抽测结果如下：K0+760K0+800中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHYK0+7603621840524599.83333.273621840.1524599.79333.274-0.0270.04-0.004YK0+7653621838.4524595.13335.4083621838.4524595.13335.391-0.022-0.0030.017YK0+7703621836.7524590.42336.5873621836.6524590.49336.6060.047-0.069-0.019YK0+7753621834.8524585.77337.1913621834.8524585.75337.251-0.0230.016-0.06YK0+7803621833524581.11337.3773621833524581.15337.3880.027-0.041-0.011YK0+7853621831.3524576.38337.7153621831.3524576.38337.7240.0350.001-0.009YK0+7903621829.6524571.69339.5043621829.6524571.75339.56-0.011-0.051-0.056YK0+7953621827.8524566.99340.1933621827.9524566.99340.181-0.028-0.0010.012YK0+8003621826524562.31342.5163621826524562.27342.5030.0350.0360.013YK3+210YK3+910中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHYK3+2103620522.3522548.06364.8633620522.3522548.12364.8360.044-0.0550.027YK3+2153620519.5522543.94365.2593620519.5522544.01365.235-0.002-0.0640.024YK3+2203620516.8522539.78365.3983620516.8522539.75365.429-0.0010.027-0.031YK3+2273620512.8522533.93368.993620512.8522533.92369.0270.0310.01-0.037YK3+2303620511.2522531.45369.6013620511.2522531.43369.580.0250.0180.021YK3+2353620508.4522527.28372.2633620508.4522527.33372.33-0.03-0.047-0.067YK3+2403620505.6522523.12374.7673620505.7522523.14374.742-0.012-0.0150.025YK3+9053620151.4521960.41382.4563620151.4521960.4382.4950.0050.015-0.039YK3+9103620148.9521956.02384.8973620149521955.99384.887-0.0610.0210.01K8+925K9+100中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHK8+9253616908.6518311.17288.7193616908.7518311.21288.755-0.024-0.044-0.036K8+9553616893.5518285.23274.4933616893.6518285.19274.542-0.0360.038-0.049K8+9583616892518282.66272.8353616892518282.68272.8770.001-0.027-0.042K8+9753616883.3518268.09273.1593616883.3518268.11273.22-0.025-0.017-0.061K9+0003616870.2518246.71272.9023616870.2518246.68272.8770.0430.0220.025K9+0193616860.2518230.58274.2593616860.2518230.6274.315-0.004-0.026-0.056K9+0253616857.1518225.52272.8783616857.1518225.5272.8890.0110.014-0.011K9+0503616844518204.2278.5793616843.9518204.27278.5910.016-0.066-0.012K9+0753616830.9518183290.8913616830.9518183.01290.8610.002-0.0130.03K9+1003616817.7518161.64298.5753616817.7518161.67298.6080.016-0.03-0.033YK14+458YK14+478中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHYK14+4583616427.7512919.03277.3133616427.7512919277.33-0.0630.029-0.017YK14+4633616429512914.2279.1423616429512914.19279.096-0.0220.0050.046YK14+4683616430.3512909.36280.683616430.4512909.41280.724-0.064-0.046-0.044YK14+4733616431.7512904.58282.3983616431.7512904.63282.454-0.05-0.048-0.056YK14+4783616433512899.76285.0283616433512899.78285.020.048-0.0190.008YK21+324YK21+349中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHYK21+3243619374.1506793.78221.5053619374.2506793.77221.544-0.0510.01-0.039YK21+3293619373506793218.9243619373.1506793.02218.975-0.057-0.021-0.051YK21+3343619375.6506783.8214.1593619375.6506783.86214.123-0.011-0.0580.036YK21+3393619376.4506778.85210.3153619376.4506778.81210.29-0.0440.0420.025YK21+3453619377.2506772.91206.5143619377.2506772.9206.5540.0070.003-0.04YK21+3493619377.8506769.02203.7063619377.8506769.04203.728-0.007-0.021-0.022YK29+340YK29+360中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHYK29+3403619245.1498943.12290.2683619245.1498943.13290.2750.003-0.007-0.007YK29+3453619244.4498938.2290.8093619244.4498938.16290.821-0.0650.046-0.012YK29+3503619243.7498933.21291.693619243.7498933.18291.725-0.0040.036-0.035YK29+3553619242.9498928.32293.7553619242.9498928.33293.7980.038-0.013-0.043YK29+3603619242.3498923.28294.5883619242.3498923.33294.565-0.05-0.0510.023K36+905K36+950中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHK36+9053619187491631.86311.1923619187491631.91311.2330.012-0.057-0.041K36+9203619182.5491617.48312.4363619182.5491617.5312.4160.014-0.0140.02K36+9343619178.6491604.13312.2153619178.6491604.1312.2760.0080.027-0.061K36+9503619174.3491588.69320.4733619174.3491588.75320.443-0.061-0.0670.03K43+525K43+580中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHK43+5253619718.4485155.41332.6133619718.4485155.38332.634-0.040.03-0.021K43+5403619723.7485141.37331.2423619723.7485141.37331.312-0.024-0.008-0.07K43+5603619730.6485122.61329.563619730.6485122.57329.5270.0090.0450.033K43+5803619737.6485103.88327.2253619737.6485103.9327.28-0.003-0.021-0.055YK58+100YK58+180中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHYK58+1003624428471824.39364.3343624428.1471824.45364.397-0.031-0.065-0.063YK58+1203624422.3471805.29366.8423624422.4471805.34366.877-0.069-0.054-0.035YK58+1403624416.5471786.08366.3293624416.6471786.12366.284-0.025-0.0470.045YK58+1603624410.8471767.01366.3413624410.9471767.06366.397-0.041-0.056-0.056YK58+1803624405471747.71366.3813624405.1471747.77366.438-0.034-0.059-0.057ZK58+000ZK58+080中桩检查表桩号X坐标Y坐标H高程检查X检查Y检查HXYHZK58+0003624436.3471918.32390.0683624436.3471918.37390.042-0.012-0.0530.026ZK58+0203624429.9471899.43378.593624430471899.49378.596-0.024-0.052-0.006ZK58+0403624423.4471880.43359.8333624423.5471880.43359.861-0.0310-0.028ZK58+0603624417.3471861.45359.7223624417
