【正文】 隨著現(xiàn)代科學(xué)技術(shù)的發(fā)展和計(jì)算機(jī)應(yīng)用技術(shù)水平的提高 ,各種理論和方法為變形分析與變形預(yù)報(bào)提供了廣泛的研究途徑。但若監(jiān)測數(shù)據(jù)為不等時距 ,必須進(jìn)行變換。該方法是建立在輸出等價原則上的等價系統(tǒng)的數(shù)學(xué)模型。 逐步線性回歸模型是建立在 F 檢驗(yàn)的基礎(chǔ)上逐個接納顯著因子進(jìn)入回歸方程。如果采用擴(kuò)展回歸法 ,則預(yù)測精度會更高。建模不需要大量的變形監(jiān)測資料 ,在變形監(jiān)測的初期就能進(jìn)行變形預(yù)報(bào)。但上述各種位移顯著性分析方法均存在如下中英文資料外文翻譯 14 缺點(diǎn)：①對于具體的形變網(wǎng) ,其點(diǎn)位移動情況不同、觀測值預(yù)處理時選擇的平差基準(zhǔn)不同 ,對位移的判定將得出不同的結(jié)論 ,有時甚至得出 錯誤的結(jié)論；②如果兩期監(jiān)測的精度不同 ,即兩期的母體單位權(quán)方差不一致 ,則不能應(yīng)用；③進(jìn)行假設(shè)檢驗(yàn)時 ,顯著水平的選取帶有極大的主觀隨意性。 Pelzer 在 1971 年提出了目前廣泛采用的整體位移顯著性分析的平均間隙法。因此 ,在變形監(jiān)測數(shù)據(jù)處理中必須進(jìn)行位移顯著性分析。因此 ,研究基于“ 3S”集成的變形監(jiān)測系統(tǒng) ,是變形監(jiān)測技術(shù)的一個重要發(fā)展趨勢。近年來 ,我國在利用GPS 進(jìn)行滑坡變形、大壩變形、礦區(qū)地面沉陷和地殼形變監(jiān)測等方面 ,做了大量的研究工作。近幾年發(fā)展起來的數(shù)字?jǐn)z影測量技術(shù) ,也在建筑物及滑坡等變形監(jiān)測中得到了成功的應(yīng)用 ,并顯示出良好的應(yīng)用前景。但外業(yè)工作量大 ,布點(diǎn)受地形條件影響 ,不易實(shí)現(xiàn)自動化監(jiān)測。 2 變形監(jiān)測技術(shù) 隨著科學(xué)技術(shù)的進(jìn)步和對變形監(jiān)測的要求的不斷提高 ,變形監(jiān)測技術(shù)中英文資料外文翻譯 12 也在不斷地發(fā)展。就地學(xué)和工程領(lǐng)域中的變形來說 ,當(dāng)變形量不超過一定范圍時 ,不會造成危害 ,而當(dāng)變形量超過變形體所能承受的允許范圍時 ,則往往會帶來嚴(yán)重的災(zāi)難。s crust deformation monitor, has done the massive research work. The GPS distortion monitor mainly has following merit： (1) The precision is higher, is bigger than 10km when the base length, its relative accuracy may achieve 106~107,obviously surpasses the tradition geodetic survey monitor technology； (2) The monitor the weather condition limit, may not carry on the allweather monitor； (3) The monitor, the record, calculated entire automatically pletes, has guaranteed monitor achievement objective and the reliability, simultaneously greatly reduced monitore dpersonnel39。中英文資料外文翻譯 1 變形監(jiān)測技術(shù) 畢業(yè)論文 中英文資料外文翻譯文獻(xiàn) 附錄 ： Distortion monitor research present situation summary [ Abstract ] this article on from distortion monitor technology, monitor data thick difference recognition, displacement analysis and distortion forecast and so on several aspects, summary distortion jail Measured the research the present situation, carries on the thorough analysis to the existing distortion monitor theory and the technical method serviceability and its the existence question, and discusses its development tendency. [ Key word ] distorts the monitor； The displacement analyzes； Distortion forecast； Research present situation 1 introduction The distortion (Deformation) is refers to the deformable body in under each kind of influence factor function, its shape, size and position in time air zone change. The nature has each kind of form the distortion, like the earth39。s labor intensity； (4) Between the test point does not need the inter visibility, the point sort not the topographical condition limit； (5) The test point three dimensional coordinates may also determine； (6) Its fishing expense approximately for convention geodetic survey technology fishing expense 1/6~1/3. Along with the puter technology, the wireless munication technology, the spatial technology and the geoscience rapid development, 3S (GPS,GIS, RS) the technology has developed from respective in dependence enters mutually integrates the fusion the stage. 3S the technical integration may for analyze and studies between each kind of information the reciprocity provide the technical strut, specially tense GIS (Temporal GIS, is called TGIS) the technical application, it may describe the fourdimensional space geological 中英文資料外文翻譯 5 phenomenon, besides has general GIS the function, but also can record studies in the region each geological phenomenon as necessary between deductive process, this to geological disaster the and so on the landslide monitor forecast has the count for much function. Therefore, studies based on 3S the integrated distortion monitor system, is distorts a monitor technology important development tendency. Moreover, carries on the engineering structure using the survey robot the automated distortion monitor, generally may select two methods according to the ac
