地下工程环境岩土工程问题研究与认识

Research on environmental and geotechnical engineering problems in underground engineering

优势面分析作为环境岩土工程与地质灾害研究的理论和方法,可为地下工程稳定性评价、设计和施工提供基础依据。将该理论运用于三峡、黑山峡、大柳树等重大水利工程,铁路囩梁山隧道、高速公路老山隧道等重要交通干线工程,苏南核电站和蓄能电站、南京市地铁等工程中。通过对工程的选址定位、安全评价、设计施工等工作中的认识和体会,就研究目标(三个稳定性和突水分析)、问题关键(找优势面、优势层)、支护设计方法(四类)、支护和防水设计的人地谐调原理(针对性、地质工程原理、顺应自然)等多方面问题作以分析和研讨。

As a research theory and analysis method of environmental and geotechnical engineering as well as geological disaster, preferred plane analysis can be used to offer scientific gist for the stability analysis, design and operation of underground engineering. The theory of preferred plane is used in many important aspects including water conservancy like the Three Gorges Project, Heishan Gorge and Daliushu, engineering of traffic main stem like Yunlianshan tunnel of railroad and Laoshan tunnel of expressway, nuclear power station and storage power station in south Jiangsu and Nanjing subway. Through understandings for site selection , safety evaluations, design and construction, the authors analyzed the research aims i.e. stability and water bursting, main problems i.e. search of preferred plane or layer, timbering design method, harmony of support and waterproof design.
