我们的工作地区是山西交城孤偃山周围,位于群山之中,山高一般都在海拔1000公尺以上,高者达2000公尺以上,地形崎岖不平,沟谷甚多,深沟陡壁交错,山坡坡度一般在30度以上,黄土复盖甚广而厚,松林遮天,灌木盖地,荆棘遍布,有时视距短至只达几公尺,在这样的情况下,测量工作极难进行,在100公尺内定控制点,常常要砍四、五十颗碗大的松树,工作初期一天只能定出三个基点,远远不能满足磁法要求,磁秤被迫停工。面对
Our work area is around Jiayinshan, Jiaocheng City, Shanxi Province. Located in the mountains, the mountains and valleys are generally over 1,000 meters above sea level, the highest reaches more than 2,000 meters. The terrain is rugged, with many valleys and deep furrows, Hillside slope is generally above 30 degrees, the loess covered a wide and thick, the pine forest, shrub cover, thorns all over, and sometimes as short as a few meters, in this case, the measurement is extremely difficult to carry out, Within 100 meters of the designated control points, often cut four or fifty large bowls of pine trees, the initial day can work out only three basis points, far from meeting the magnetic method requirements, magnetic scales were forced to stop work. face
