城市地下空间地质调查工作目前在全国许多城市中如火如荼地开展,选择合适的调查手段会使得这项工作事半功倍。一些物探方法凭借其无损、高效、抗干扰能力强等优点在城市地质调查工作中备受青睐,但是面对城市复杂的工况,单一的物探方法... 城市地下空间地质调查工作目前在全国许多城市中如火如荼地开展,选择合适的调查手段会使得这项工作事半功倍。一些物探方法凭借其无损、高效、抗干扰能力强等优点在城市地质调查工作中备受青睐,但是面对城市复杂的工况,单一的物探方法往往无法有效探明城市地下地质构造,须通过多种物探手段联合开展勘察,相互佐证,才能真正有效地对城市地下地质构造进行精细查找。等值反磁通瞬变电磁法和微动法是近几年来发展较快的物探方法,广泛地应用于各个领域。本文以成都市地下空间调查工作中包江桥隐伏断层探测工作为背景,将等值反磁通瞬变电磁法和微动法联合起来探测该隐伏断层的具体位置和走向,最后将综合物探成果与以往地质调查资料作对比,结果吻合性基本一致,证明该综合物探组合在强干扰的城市环境中能够有效识别隐伏断层位置,为城市地下空间调查工作提供了一种行之有效的物探组合手段。 展开更多

Currently domestic researches on urban imago space concentrate in a few cities that lie in the advanced region, such as Beijing, Guangzhou, Wuhan, etc., but in so far as those cities that lie in the northwest inland region, the research of this aspect is still few. In order to supplement a special example to the urban imago space theory and to validate former theory, this article studied the Lanzhou urban imago space. During the course of researching, authors adopted some investigating methods, such as visiting on the spot, photograph identification method and sketch map identification method etc. Using investigated data, this paper made an elementary research on urban imago space of Lanzhou, which is a typical valley city in the western China. The result of study indicated that the urban imago space of Lanzhou takes Xiguan Cross as its center (Lanzhou involves four districts of Chengguan, Qilihe, Anning and Xigu). In the process of recognition of urban imago space, the Huanghe (Yellow) River and mountains beside the city are the dominant factors and the main nodes of cognition. So the urban imago space of Lanzhou is quite different from that of plain cities. Interviewee did well in the spatial structure map, which was made up of mountainous land, river and main trunk roads,the group structure took profound impression on people. 展开更多
