基于GIS的地下工程选址技术与应用
GIS-based site selection techniques and application of underground engineering
【摘要】 为解决常规地下工程选址方法工作量大、成本高且受时间、地域、地形限制,勘测选址不便的问题,通过深入分析地下工程与地质背景的依存关系,研究并提出了基于GIS的地下工程选址技术。结合工程实践与实测试验研究构建了地下工程选址所需的工程技术指标与遥感指标集之间的数学映射关系模型。以GIS为分析平台,利用多因素交叉耦合选址理论实现地下工程选址评价,有效提高地下工程选址的时效性与工作便捷性,同时还可节约前期勘察成本。经青藏高原西部某地区初步应用,取得较好的应用效果。
【Abstract】 In order to solve the problems of large workload,high cost and inconvenience in site selection due to time,region and topography limitation in conventional underground engineering site selection methods,the GISbased site selection techniques of underground engineering was presented through in-depth analysis of the dependence between underground engineering and geological background. The mathematical mapping model between remote sensing index set and engineering technical index for underground engineering site selection was constructed based on engineering practice and actual test. Taking GIS as an analyzing platform,the location theories of multifactor cross coupling were used to evaluate the location of underground engineering works,which effectively improved the timeliness and convenience of underground engineering site selection,and saved the initial exploration cost. Preliminary application in a region of western Qinghai-Tibet Plateau has achieved good results.
