摘要

摘要: 运用兰州新区最新地质构造、地震及勘察研究成果，结合新区建设进程中崩塌、滑坡、泥石流、不稳定斜坡、土壤盐渍化等对城市构成威胁的环境地质与灾害地质问题。在兰州新区地貌和划分的岩土体类型基础上，根据区内工程地质条件的相似性和差异性，对兰州新区工程地质条件研究，将新区划分为堆积盆地工程地质区和丘陵工程地质区两个区。其中，丘陵工程地质区分为稳定、较稳定、稳定性较差3个亚区。堆积盆地工程地质区和稳定的丘陵工程地质亚区岩（土）体稳定性好，工程地质条件好；较稳定的丘陵工程地质亚区岩（土）体稳定性较好，工程地质条件较好，这些区域可作为新区今后重点开发建设的区域。此项研究成果对兰州新区规划建设和工程建设适宜性评价具有重要的指导意义。

Abstract: Based on the latest research results on geological structure, earthquake and investigation in Lanzhou New Area, combined of the environmental geological problems that collapses, landslides, debris flow, instability slope and salinization have been developing in Lanzhou new 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 new area were studied by dividing the whole new area into 2 kinds of zones-soil body stability and by further dividing them into three sub zones, with the conclusion that new area could be divided into accumulation basin district area of engineering geology and engineering geology area at the two districts. Among them, the hills of engineering geology is divided into stable, relatively stable, poor stability three sub zones. Engineering geology accumulation basin area and the stability of engineering geology area at the rock(soil) mass good stability and good engineering geological conditions. Relatively stability of the engineering geology area at the rock(soil) mass stability is better. The engineering geological condition is good, and can be used as the focused development and construction areas in Lanzhou new area in the future.
