摘要
针对西安市区的地质环境和地面沉降特征,总结国内外与此相关的研究成果,重点从土层渗流与变形特性、地面沉降和地裂缝的关系、下部地层压密与地面变形关系以及开采地热资源对地面沉降的影响等几个方面分析西安市区地面沉降研究的现状及存在的问题,并针对这些问题提出了几点建议。
According to the characteristics of geological environment and land subsidence in Xi＇an urban area, the results of the related research at home and abroad are summarized. The present situation and problems in the research on land subsidence in Xi ＇an are analyzed in the light of the relations of seepage flow in aquifer with deformation, land subsidence with ground fissures and compaction of the lower layers with ground deformation and of the effect of geothermal resources exploitation on land subsidence. Finally some suggestions are offered.
