Comments on Matching Geology with Physical Exploration in Engineering Geological Prospecting for Large Deep Buried Tunnel

研究目的:长大深埋隧道的出现向传统的工程地质勘察方法提出了新的挑战,以大地电磁类为主的深层物探方法给这一问题的解决提供了有利地支撑。地质资料是物探解释的基础,没有地质和物探的密切配合很难取得良好的物探效果。本文研究的目的通过人员配备建立一种工作机制以提高物探工作水平,进而提高长大隧道勘察质量。研究方法:结合工程实践,总结以往地质与物探不同配合模式的特点,以不同配合方式下物探成果的质量为标准,进而对长大复杂隧道的地质勘察推荐出一种地质人员全过程配合物探的工作模式。研究成果:总结了不同阶段地质配合物探的工作内容,并对地质人员全过程配合物探工作这一方式的工作方法和工作内容做了详细论述;结合工程地质勘察的阶段要求,提出了不同勘察阶段物探工作原则、工作深度和应采用的物探手段。研究结论:长大深埋隧道的工程地质勘察,只有在综合勘探中大力推广高水平的物探,再辅以专职地质专业人员的全过程密切配合,才能取得良好的效果。

Research purposes： The occurrence of large deep buried tunnel made a new challenge to the traditional way for engineering geological prospecting and the deep physical exploration of magneto - telluric exploration provided support for solving such problems. The geological information was the basic interpretation for physical exploration and no good result of physical exploration could be obtained without matching geology with physical exploration. The purpose of this paper was to increase the working level of physical exploration and exploration quality for large deep buried tunnel through establishing a working system with equipping certain persons. Research methods： The features of different modes for matching geology with physical exploration in the past were summed up through construction practice. A new working mode was commended for matching geological person with physical exploration in geological exploration for large complicated tunnel based on taking the quality of physical exploration under different matching modes as standard. Research results： The working contents of matching geology with physical exploration in every stage were summed up. The working way and content were described in details for matching geological person with physical exploration. The working principle, content and way of physical exploration were presented for physical exploration in every stage according to the requirements of engineering geological prospecting. Research conclusions. The good result of engineering geological prospecting for large deep - buried tunnel could be obtained only if physical exploration of high level could be adopted widely in overall exploration with assistance of matching given by professional geological person.
