兰州城市区工程地质分区研究
|
摘要
运用兰州市最新地质构造、地震研究成果,结合城镇化进程中兰州市区南北山前崩塌、滑坡及泥石流灾害发育,对城市构成严重威胁的现实客观因素.在已有地貌和岩土体类型划分基础上,根据工程地质条件的相似性和差异性,重新进行兰州市区工程地质条件研究,将城区划分为岩(土)体稳定性好、中等及差三个区、六个亚区.其中安宁区迎门滩、七里河区崔家大滩高漫滩岩(土)体稳定性好,工程地质条件好;安宁堡至十里店一带、七里河区职工医院至文化宫一带的Ⅰ、Ⅱ级阶地岩(土)体稳定性中等,工程地质条件较好,这些区域可作为城市区今后重点开发建设的区域.
Based on the latest research results on geological structure and earthquake in Lanzhou City, combined of the objective factors that collapses, landslides and debris flow disasters have been developing in the north and south piedmonts of Lanzhou urban areas during the process of urbanization and other serious threats to the city, by means of the existed classifications of topography and divisions of rocks and soils type, and according to the rules of similarity and differences for classifying the engineering geological conditions, the urban engineering geological conditions in Lanzhou City were studied by dividing the whole urban area into 3 kinds of zones of good, medium and poor rock-soil body stability and by further dividing them into six sub zones, with the conclusion that Yingmentan in Anning District and Cuijiadatan in Qilihe District are of good rock-soil body stability and their engineering geological conditions are also good; the places from Anningbao to Shilidian and from Zhigongyiyuan in Qilihe District to Wenhuagong are of medium rock-soil body stability, and they are also under medium engineering geological conditions and can be used as the focused development and construction areas in Lanzhou City in the future.
