【摘要】：建立高精度的地殼運(yùn)動速度場模型是實現(xiàn)區(qū)域大地基準(zhǔn)動態(tài)維持,反映地面形變,保障基礎(chǔ)設(shè)施工程建設(shè)的重要途徑。針對點位分布密集、精度可靠和多年連續(xù)重復(fù)觀測等準(zhǔn)確獲取區(qū)域地殼運(yùn)動速度場模型的關(guān)鍵問題,通過對山東及周邊省份2010年1月—2015年11月連續(xù)近6a的130座連續(xù)運(yùn)行參考站點在ITRF2008框架下進(jìn)行處理,獲取時間序列。首次完整建立了山東省地殼運(yùn)動速度場模型。通過模型分析表明:水平方向,山東省地殼整體向東南方向運(yùn)動,平均速率為34.3mm/a,運(yùn)動方向為SE110.25°;垂直方向,魯中山區(qū)及膠東半島地區(qū)地殼較為穩(wěn)定,魯北、魯西等華北平原地區(qū)存在顯著沉降,最大沉降量位于廣饒漏斗區(qū),年沉降量81.6mm/a。
[Abstract]:Establishing a high precision velocity field model of crustal movement is an important way to realize the dynamic maintenance of regional geodetic datum, to reflect ground deformation and to ensure the construction of infrastructure engineering. The key problems in accurately obtaining the velocity field model of regional crustal movement, such as reliable accuracy and continuous and repeated observation for many years, are discussed. Through the processing of 130 continuous operation reference stations in Shandong and its surrounding provinces from January 2010 to November 2015 for nearly 6 consecutive years, under the framework of ITRF2008, The velocity field model of crustal movement in Shandong Province is established for the first time. The results of model analysis show that the horizontal direction, the whole crust of Shandong Province moves southeast, the average velocity is 34.3 mm / a, the direction of movement is SE110.25 擄, the vertical direction is vertical. The crust is stable in Shandong Central Mountain area and Jiaodong Peninsula, and there is significant subsidence in North China Plain, such as North Shandong and West Shandong. The maximum subsidence is located in Guangrao funnel area, and the annual subsidence is 81.6 mm / a.
