摘要： 城市新区的科学选址及规划需要以明确的工程地质条件为基础，因此开展城市周边工程地质分区研究已成为当前城镇发展工作中的关键环节。本文以铜川地区为例，根据地质构造及地貌演化确定了地貌类型，依据第四纪沉积物组合差异将地层沉积结构划分为风成沉积型、冲洪积型及风成-冲洪积复合沉积型。根据湿陷性试验结果，研究区内黄土埋深超过22 m不具自重湿陷性，埋深超过24 m不具湿陷性；根据湿陷量计算值将研究区划分为非湿陷区、2级、3级和4级湿陷区。在此基础上将研究区划分为4个区（低中山区、黄土台塬区、黄土丘陵区和河谷阶地区）及8个亚区，并总结了各工程地质区的工程特性，其中：低中山区及黄土丘陵区不适宜建筑；黄土台塬区的2级湿陷高台塬亚区和2级湿陷低台塬亚区为适宜建筑；河谷阶地区部分适宜建筑；黄土台塬区的3级、4级湿陷高台塬亚区及3级、4级湿陷低台塬亚区进行地基处理后适宜建筑。研究成果可为黄土高原地区相似地质条件下的未来城市选址及工程建设规划提供指导和借鉴。

Abstract: As a key link in the current urban development, the scientific site selecting and planning of a new urban area needs to be based on the clear engineering geological conditions.Taking Tongchuan region as an example,according to the latest geological structure and landform evolution, we determined the types of landform and divided the the sedimentary structures into eolian deposition, fluvial and pluvial deposition, and complex deposition in respect of the Quaternary sediments. According to the results of collapsibility tests, the depth more than 22 m of the loess in the study area is without self-weight collapsibility, and the depth more than 24 m is without collapsibility. Based on the calculation of the collapsibility amount, the study area is graded into non-collapsible areas, level 2, level 3, and level 4 collapsible zone. There are 4 zones (low mountainous, loess platform, loess hilly, andvalley terrace) and 8 sub-zones. On the basis, we summarized the engineering characteristics of each engineering geological area. Of them, the low mountainous areas and loess hilly areas are not suitable for construction; while the level 2 collapsible of high and low loess plateau, part of valley terrace areas after a foundation treatment,and level 3-4 collapse of high and low loess plateaus are suitable for construction. The research results provide some guidance and reference for future urban site selection and project construction planning under similar geological conditions in Loess Plateau.

Key words: Loess Plateau, collapsibility, engineering geological condition, engineering geological division, Tongchuan region
