In chapter three , the author makes a comprehensive analyze of the nation ' s pipeline construction market . on the one hand , the author points out that we have met the new pinnacle of pipeline construction with the country ' s increasingly fast economic development . and on the other hand , there emerge quite a number of strong competitors which have deeply influenced cpplb because of the more opening market 第三章节,比较全面的对国内管道建设的市场进行了分析研究,既看到了随着国家经济建设速度的稳步上升,我们又迎来“经济血脉”即管道建设的新高潮,同时也以诸多案例为证,客观地指出随着国内市场尤其是行业市场的不断开放,培养了一批在管道设计和施工建设方面具有一定实力的竞争对手,对cpplb在管道设计和施工方面均形成了较大的冲击波。
Taking zibo - qingdao natural gas pipeline engineering for example , starting with the present crossing river modes for gas transport pipeline , the main contents and methods of geotechnical engineering investigation for pipeline crossing river are put forward ; the existential geotechnical engineering problems and relevant countermeasures in the course of design and construction of this pipeline engineering ' s crossing river project are analyzed and evaluated ; the importance of geotechnical engineering investigation in the design and construction of long distance pipe lines is pointed out 摘要以淄青天然气管道工程为例,从目前输气管道河流穿跨越方式入手,提出了管道穿越河流岩土工程勘察的主要内容和方法,分析评价了淄博青岛输气管道工程河流穿越工程设计及施工过程中存在的岩土工程问题及相应的对策,指明了岩土工程勘察在长输管道设计及施工中的重要性。
