青岛主城区地下空间开发利用地质因素的影响评价及适宜性分区

Evaluation and suitability zoning of geological factors affecting the development and utilization of underground space in the main urban area of Qingdao

根据青岛市主城区的工程地质特征以及工程建设经验,综合分析岩土体的特征、地下水、地质构造及软土等主要约束地下空间开发利用的地质因素的发育分布特征,并采用模糊综合评判法对主城区地下开发适宜性进行评价,将主城区地下空间开发适宜性划分为适宜区、基本适宜区和适宜性差区,并进行了分区评价,适宜区占主城区总面积的79%,适宜地下空间开发;基本适宜区占主城区面积的13%,地下空间适宜性一般,地下空间开发时应着重注意加固及防水措施;适宜性差占主城区面积的8%,地下空间开发时因尽量避开。

Based on the engineering geological characteristics and engineering construction experience in the main urban area of Qingdao City,the characteristics of rocks and soil mass,groundwater,geological structure and soft soil are comprehensively analyzed.The suitability of underground development in the main urban area is evaluated using fuzzy comprehensive evaluation,and the suitability of underground development in the main urban area is divided into suitable area,basic suitable area and poor suitable area.The zoning evaluation is also carried out.The results show that the suitable area accounts for 79%of the total area of the main urban area and is suitable for underground space development;the basic suitable area with general suitability accounts for 13%and reinforcement and waterproofing measures should be paid attention to in the development of underground space;the poor suitability accounts for 8% and should be avoided for further underground space development as much as possible.
