【摘要】：2017年2月19日3:45左右,甘肅省永靖縣黑方臺(tái)羅家坡發(fā)生滑坡。針對(duì)滑坡災(zāi)害應(yīng)急過(guò)程中對(duì)滑坡滑體厚度和體積精確計(jì)算的難題,本文采用無(wú)人機(jī)航測(cè)系統(tǒng),獲取滑坡前后的高精度DEM數(shù)據(jù)源,并結(jié)合現(xiàn)場(chǎng)調(diào)查,精確計(jì)算出滑坡堆積區(qū)厚度的分布情況。研究結(jié)果表明,羅家坡2#滑坡長(zhǎng)525 m,總面積約5.65×104m2,滑坡體總體積約14.7×104m3,最大滑距為368 m,滑坡剪出口位于第四系上更新統(tǒng)沖積粉質(zhì)黏土頂部,堆積區(qū)最大埋深8.35 m,位于滑坡滑舌的西南側(cè)。根據(jù)DOM影像和現(xiàn)場(chǎng)調(diào)查,該滑坡危害對(duì)象以農(nóng)田和水渠為主,無(wú)房屋受損和人員傷亡,本文通過(guò)引入無(wú)人機(jī)航測(cè)系統(tǒng)為滑坡應(yīng)急搶險(xiǎn)救災(zāi)提供了一種新的研究方向。
[Abstract]:At about 3:45 on February 19th 2017, a landslide occurred in Luojiapo, Heifangtai, Yongjing County, Gansu Province. Aiming at the difficulty of accurately calculating the thickness and volume of landslide slide body in the emergency process of landslide disaster, the UAV aerial survey system is used in this paper. The high precision DEM data source before and after landslide is obtained, and the distribution of the thickness of the landslide accumulation area is calculated accurately by combining with the field investigation. The results show that, Luojiapo 2# landslide is 525m long, with a total area of 5.65 脳 104m2.The total volume of the landslide is about 14.7 脳 104m3.The maximum slip distance is 368 m.The exit of the landslide is located at the top of the Quaternary Upper Pleistocene alluvial silty clay. The maximum buried depth of the accumulation area is 8.35 m, located in the southwestern side of the slippery tongue of the landslide. According to the DOM image and field investigation, the landslide is mainly caused by farmland and canals, and there are no house damage or casualties. In this paper, the introduction of UAV aerial survey system provides a new research direction for landslide emergency rescue and relief.
