工業(yè)大學(xué)測(cè)量學(xué)一作業(yè)題[2015].doc

測(cè)量學(xué)一作業(yè)題一、如圖2-19所示，測(cè)區(qū)附近有一已知高程的水準(zhǔn)點(diǎn)，欲求得1、2、3點(diǎn)的高程，可從點(diǎn)起進(jìn)行水準(zhǔn)測(cè)量，經(jīng)過1、2、3點(diǎn)再回到點(diǎn)，形成一個(gè)閉合水準(zhǔn)路線。各段觀測(cè)高差及路線長(zhǎng)度如圖所示。 閉合水準(zhǔn)導(dǎo)線圖2-20 附合水準(zhǔn)導(dǎo)線二、如圖所示，從已知高程的水準(zhǔn)點(diǎn)開始測(cè)量，附合至另一己知高程的水準(zhǔn)點(diǎn)。今欲測(cè)點(diǎn)高程。三、豎直角觀測(cè)數(shù)據(jù)列于下表中，試完成其記錄和計(jì)算。No.94356天頂為0測(cè)站目標(biāo)盤左讀數(shù) 盤右讀數(shù) 水平始讀數(shù) 豎直角 天頂距 98 41.3261 18.886 16.4250 35.797 26.5四、用光學(xué)經(jīng)緯儀按測(cè)回法觀測(cè)水平角，測(cè)得水平度盤的盤左和盤右讀數(shù)如圖所示，列表進(jìn)行記錄和計(jì)算，并說明角值是否在允許誤差范圍內(nèi)？若在允許誤差范圍內(nèi)，一測(cè)回角值是多少？如超限，該如何處理 ？ 五、丈量、兩段水平距離。往測(cè)為126.780，返測(cè)為126.735；往測(cè)為357.235，這測(cè)為357.190。問哪一段丈量精確？為什么？?jī)啥尉嚯x的丈量結(jié)果各為多少？六、已知點(diǎn)的磁偏角為，過點(diǎn)的真子午線與中央子午線的收斂角，直線的坐標(biāo)方位角，求的真方位角和磁方位角，并繪圖加以說明。七、何謂直線的正、反坐標(biāo)方位角？若按下圖所示傳遞坐標(biāo)方位角，已知,測(cè)得，求邊的坐標(biāo)方位角。八、甲、乙兩組對(duì)同一個(gè)平面三角形分別觀測(cè)了10次，三角形內(nèi)角和的真誤差為甲組 乙組 計(jì)算這兩組觀測(cè)值的平均誤差和中誤差。九、獨(dú)立觀測(cè)值 、的中誤差分別為、，某函數(shù)為，求其中誤差。十、某建筑物基礎(chǔ)設(shè)計(jì)為正六邊形?？⒐y(cè)量中，分甲、乙兩組測(cè)定其周長(zhǎng)。甲組丈量一條邊長(zhǎng)為，乙組丈量六條邊長(zhǎng)分別為則、。丈量的中誤差均為，試比較兩組所求周長(zhǎng)的精度。十一、如圖所示的附合導(dǎo)線中，已標(biāo)出已知數(shù)據(jù)和觀測(cè)數(shù)據(jù)，計(jì)算2，3兩點(diǎn)的坐標(biāo)。習(xí)題5-14圖十二、在帶高斯平面系中，、兩點(diǎn)的坐標(biāo)為：，；，。試計(jì)算 邊的坐標(biāo)方位角和邊長(zhǎng)。十三、地面某點(diǎn)的經(jīng)度，試求該地面點(diǎn)所在帶和帶的帶號(hào)及其中央子午線的經(jīng)度。十四、根據(jù)圖繪制M、N兩點(diǎn)間的斷面圖。十五、已知某區(qū)地形點(diǎn)坐標(biāo)（點(diǎn)號(hào)，X，Y，Z）如下，試畫出等高線圖。1,500000.0000,300000.0000,650.0000,4,500000.0000,300012.4887,650.6613,5,499993.6843,300004.8272,650.2938,6,500007.6585,300010.5926,650.7039,7,500023.0234,300019.0523,652.2059,8,500030.0383,300013.7579,653.0508,9,500036.9233,299999.5813,655.1371,10,500043.3832,299985.8998,655.1297,11,500042.0911,299971.4638,651.3122,12,500040.0173,299959.1801,647.2404,13,500037.6305,299944.6533,644.5392,14,500038.0621,299931.0245,640.7354,15,500038.2016,299923.8026,639.1459,16,500033.7875,299908.5310,633.9054,17,500024.7619,299911.9132,631.5592,18,500033.1310,299916.7466,635.6923,19,500033.6018,299924.6127,636.9840,20,500027.7382,299924.8335,633.8691,21,500030.1264,299927.6873,637.1033,22,500030.4651,299938.0981,640.1747,23,500030.9718,299942.0213,640.7937,24,500032.1993,299944.5369,641.6695,25,500037.2834,299947.4849,644.9099,26,500036.4741,299952.0597,645.5318,27,500034.3590,299956.5598,644.4035,28,500026.3210,299941.9508,625.4035,29,500038.1757,299961.9861,647.9183,30,500035.7695,299961.8460,645.2685,31,500035.8220,299973.1844,649.6052,32,500036.6379,299981.7880,651.3210,33,500034.8227,299982.9322,651.1158,34,500033.8373,299988.4226,653.7051,35,500032.2139,299988.0931,651.1798,37,500033.1305,299996.8901,653.3643,38,500030.9675,299997.0992,652.6075,39,500030.8864,300002.9057,653.1246,40,500024.6335,300008.9151,650.7803,41,500029.2743,300001.7030,649.1154,42,500027.1446,299992.4251,645.1772,43,500027.9917,299980.2270,639.2619,44,500030.3691,299972.8612,635.5062,45,500028.8083,299967.5815,632.4163,46,500028.5147,299951.2116,626.7351,47,500027.8657,299935.7395,624.9474,48,500024.8098,299922.7290,623.1860,49,500014.3811,299918.8940,623.5641,50,500005.6093,299909.1494,623.5910,51,499999.8701,299927.9743,623.9831,52,499985.5920,299949.7636,627.8775,53,500006.5200,299932.9787,624.2305,54,500017.6549,299941.1395,625.3937,55,500026.0027,299957.5869,628.0127,56,500007.9428,299956.2791,628.5563,57,499993.1361,299956.9157,628.8152,58,499977.8380,299961.8909,631.4972,59,499978.3143,299973.3781,638.5733,60,499992.1218,299972.4053,638.9551,61,500007.0593,299973.9004,639.1250,62,500027.7562,299979.2315,638.9257,63,500026.6599,299983.2480,639.8592,64,500013.6703,299979.9947,639.6206,65,499997.5637,299978.0300,639.6537,66,499981.4610,299977.3339,639.6588,67,499971.3398,299991.7726,649.2741,68,499989.1837,299997.5224,649.8099,69,500011.1585,300001.0635,650.1476,70,500027.2054,300003.9006,650.1935,71,500039.7446,300019.0751,654.1577,72,500049.6378,299999.4535,657.7609,73,500059.0023,299984.9459,658.0090,74,500068.6943,299972.5196,660.0112,
