渝北洛碛垃圾餐厨处理工程岩土工程勘察放样测量技术说明

PAGE渝北洛碛垃圾餐厨处理工程岩土工程勘察详细勘察钻孔放样测量技术说明二〇一六年十月项目名称：渝北洛碛垃圾餐厨处理工程岩土工程勘察放样测量报告名称：渝北洛碛垃圾餐厨处理工程岩土工程勘察测量员：项目负责：审核：二〇一六年十月测量依据:1.根据广西华蓝岩土工程有限公司关于渝北洛碛垃圾餐厨处理工程岩土工程勘察方案平面布置图及重庆市勘测院提供的测量控制点作为本次测量的依据，该图坐标系统为重庆独立坐标系统，高程系统为1956年黄海高程系统。二、.执行规范《工程测量规范》(GB50026-2007);《卫星定位城市测量规范CJJT73-2010》;《全球定位系统实时动态测量(RTK)技术规范》；《1：500、1:1000、1：2000地形图图式》（GB/T7929-1995）；《测绘技术总结编写规定》（CH1001-91）；《测绘产品检查验收规定》（CH1002-95）；《测绘产品质量评定标准》（CH1003-95）。三、已知控制点成果及利用测区所收集到的已知平面控制起算点成果系重庆市勘测院提供，为重庆独立坐标系，高程为1956年黄海高程系。已知点成果如下：编号XYZGPS183647.78395438.21278.429GPS283646.05095394.828278.5211.根据广西华蓝岩土工程有限公司提供的洛碛垃圾应急填埋场对外交通工程岩土工程勘察方案平面布置图解算出各钻孔坐标。然后根据已知平面控制点,使用中海达V30RTK，根据图解出来的孔位坐标在实地上放出各孔位置。四、RTK放样的实施：（1）基准站选设①基准站选设在视野开阔，高度截止角大于15°，且周围无大面积水域、大型建筑物等信号反射较强的地方，同时应尽量避免交通工具与行人的干扰。②基准站应设置在测区相对内地势相对较高的控制点上，以便差分信号的播发。③在选设基准站时还应远离微波塔、通信塔等强电磁发射源200米外，同时还应该远离高压输电线50米外。④基准站点选设好后留有专人进行看管、检查设备的运行情况。（2）放样实施由于GPS采用的是WGS84地心坐标系，高程为大地高，而测区为北京坐标系，高程为正常高，因此必须进行参数转换和高程拟合。考虑到实际情况，平面采用两个已知点进行四参数转换，第三点进行检核，高程采用固定差改正进行高程拟合，经检验精度全部符合要求。设置好基准站和流动站一系列参数后，采用基准站发射出的差分信号进行放样了，平面精度控制在5cm内，并实测出高程记录在手簿中。放孔前进行了已知控制点检查，详见测量控制点自检表1，各钻孔坐标及孔口标高见附表2。附：测量控制点自检表1测量控制点自检表工程名称:渝北洛碛垃圾应急填埋场岩土工程详细勘察钻孔放样测量比例尺:1：500图幅号：同精度检测□检测方式:GPS单位：米仪器名称、型号：中海达V30仪器编号：30106443001979同精度检测□点名已知数据实地检查数据较差（mm）备注纵坐标X横坐标Y高程H纵坐标X横坐标Y高程H△X△Y△HNO140961784.26272315.935270.00661784.26172315.937270.009-0.0010.0020.003N0141061848.23572361.177267.49261848.23772361.179267.4910.0020.002-0.001检查者：田园刘钊卿检查日期：2016年7月29日各钻孔坐标、实测孔口标高见表2：钻孔基本数据钻孔坐标孔口高程钻孔编号xyZK183623.7296008.62277.78ZK283600.0196034.52276.25ZK383577.6796068.85277.06ZK483607.9495997.40272.96ZK583587.0496028.46271.65ZK683558.9996065.72269.40ZK783540.2096098.89264.79ZK883592.5195985.90274.00ZK983570.6796017.16271.42ZK1083543.7596055.39269.32ZK1183589.3095962.42282.24ZK1283569.3595992.20277.11ZK1383543.7296023.85270.60ZK1483525.7996052.06269.57ZK1583512.5496083.12270.60ZK1683493.0196111.23279.43ZK1783489.2296142.13264.48ZK1883427.3396224.95226.88ZK1983569.4195948.41291.88ZK2083552.4095979.05280.71ZK2183529.5596010.63272.23ZK2283505.5796037.76275.78ZK2383485.3396061.46280.06ZK2483460.8696092.26294.37ZK2583447.1096105.92285.60ZK2683439.3196147.39258.97ZK2783421.8396146.67260.28ZK2883398.0096207.39238.23ZK2983551.2395936.85290.78ZK3083531.6895964.98275.90ZK3183508.5395996.23274.25ZK3283483.4596022.56281.13ZK3383462.8596044.20292.14ZK3483441.3996075.42299.38ZK3583395.5396162.56255.33ZK3683372.8196199.59241.15ZK3783354.8596228.61244.06ZK3883554.8595869.66309.57ZK3983542.1495890.01300.94ZK4083515.1495928.11280.60ZK4183491.8595959.16277.45ZK4283463.8295997.75287.72ZK4383443.6096027.19294.42ZK4483415.0196067.41296.61ZK4583402.4896094.57293.63ZK4683412.1996074.17293.63ZK4783349.6996153.75241.77ZK4883333.3496173.33234.54ZK4983313.1096203.12231.08ZK5083280.3896251.63227.62ZK5183258.3996285.18225.40ZK5283241.2496314.79225.20ZK5383479.7995904.13287.72ZK5483457.0095935.90294.86ZK5583430.9095973.10300.69ZK5683409.3796003.29291.82ZK5783382.4896043.15299.91ZK5883377.2596068.01291.64ZK5983358.0796081.85291.64ZK6083321.9996114.45254.17ZK6183298.2196151.14241.87ZK6283278.7796181.46239.19ZK6383247.8096230.25234.95ZK6483225.6396263.89223.25ZK6583204.5996296.17221.05ZK6683562.1695749.86286.04ZK6783551.4195764.37292.04ZK6883528.7395802.23292.22ZK6983515.1195821.83294.39ZK7083499.6695831.69295.63ZK7183486.0695852.51296.99ZK7283557.8595712.97287.98ZK7383545.5195734.89292.17ZK7483529.5495757.64299.22ZK7583509.9795782.50301.87ZK7683492.1195810.46295.91ZK7783482.5295819.75298.83ZK7883475.4095831.03302.60ZK7983450.2095883.27301.75ZK8083427.4595915.73309.44ZK8183401.3595953.07304.24ZK8283380.4195982.45286.70ZK8383356.9296024.61291.34ZK8483337.6396048.60282.96ZK8583335.8796056.54280.60ZK8683545.7195681.65291.79ZK8783535.7295695.50293.84ZK8883526.0895709.05300.79ZK8983532.6795685.40294.25ZK9083521.0695677.91295.53ZK9183514.4595712.81305.16ZK9283497.0295737.28303.64ZK9383480.8095762.58295.91ZK9483467.1595793.02294.35ZK9583456.7895801.77300.99ZK9683448.3295814.15306.43ZK9783406.4495852.27308.63ZK9883384.2195883.28301.83ZK9983360.3995920.51296.77ZK10083337.9195950.75282.12ZK10183309.8995990.67276.45ZK10283292.0796014.00274.50ZK10383292.5596035.11268.93ZK10483259.6296088.15234.70ZK10583246.1696110.46230.80ZK10683223.0396135.03227.80ZK10783209.5096204.82228.55ZK10883186.8996238.39221.63ZK10983164.3396274.45232.04ZK11083286.4495989.87279.19ZK11183266.1096015.59274.03ZK11283232.4096068.55236.30ZK11383210.7596094.18228.20ZK11483202.8996117.58226.90ZK11583180.9596150.21223.74ZK11683174.9396182.60221.77ZK11783153.3496216.49225.64ZK11883155.6996171.10221.65ZK11983129.3096212.67230.98ZK12083111.9596238.10236.70ZK12183080.4396288.08222.65ZK12283416.3595786.67294.21ZK12383396.5595812.97296.81ZK12483407.3195770.27287.54ZK12583383.1195805.11293.30ZK12683362.3495827.97294.46ZK12783339.5195860.56284.22ZK12883329.6095895.44283.44ZK12983295.8195922.66278.93ZK13083270.8395958.88288.04ZK13183258.7995970.61291.00ZK13283247.5695986.54285.12ZK13383240.5595997.06279.14ZK13483203.6396052.06242.50ZK13583174.1496098.66235.48ZK13683212.6196006.
