中缅油气管道穿越铁路防护工程设计

Design for the Sino-Burma Oil and Gas Pipe Line Through Railway Protection Engineering

以中缅油气管道穿越铁路防护工程为例,分别介绍云南省内管道穿越铁路顶管、框架涵及隧道3种防护形式。由于云南地区地质复杂,结合项目特点,详细对顶管减阻、高水位淤泥质粉质黏土中框架涵顶进及粉细砂地层暗挖隧道防护措施进行了论述;同时对高压油气管道穿越铁路防护工程防火防爆设计进行了介绍。

Taking the Sino-Myanmar oil and gas pipeline crossing railway protection engineering as an example, this thesis introduces three protection forms including pipe-jacking, framing and tunnel respectively for pipeline crossing railway in Yunnan province. Because of the complicated geology in Yunnan area, the thesis makes a detailed discussion on pipe-jack- ing friction reduction, framework culvert jacking in high water level silt clay and silty sand underground tunnel excavation protection method according to the project features. Meanwhile, the design of fire and explosion protection of high pressure oil and gas pipeline crossing railway protection engineering is also introduced in the thesis.
