我院经常承担本省三江平原地区的公路工程地质勘察任务,通过航摄像片的初步应用,不仅加快了勘察工作的进度,而且也提高了成果质量,为建造优质公路提供了可靠的依据。三江平原位于黑龙江省东北部,由松花江、黑龙江和乌苏里江冲积形成的低平原。地面普遍复盖着第四纪松散沉积物,在平原西南部边缘区和平原中的残山孤丘附近,地面复盖沉积物厚度一般为50～100米,在平原中部却为120～200水,最厚可达280 Our college often undertakes the task of highway engineering geological survey in Sanjiang Plain in our province. Through the initial application of aerial photography, not only the progress of survey work is accelerated, but also the quality of achievements is improved, which provides a reliable basis for the construction of high-quality highways. Sanjiang Plain is located in the northeastern Heilongjiang Province, the Songhua River, Heilongjiang and the Wusuli River formed by the alluvial low plain. The ground generally covers Quaternary unconsolidated sediments. In the marginal area of ​​the southwestern plains and in the plains, the thickness of the ground cover sediments is generally 50-100 meters, while in the middle of the plains it is 120-200 , The thickest up to 280
