浸水地区燃气管道防护涵方式穿越地铁

Gas Pipeline Protective Culvert Crossing Subway in Immersed Area

结合工程实例,针对浸水地区(指地下水位较高的地区)城镇燃气管道采用防护涵方式穿越地铁,分析规范对防护涵设计的要求,提出半填充防护涵的设计要点,给出半填充防护涵的断面形式,探讨浸水地区防护涵抗浮设计计算方法。

Combined with engineering examples,in view of city gas pipeline protective culvert crossing subway in immersed area( referring to area with higher groundwater level),the requirements of the standard for the design of protective culverts are analyzed. The key design points of semi-filled protective culvert are proposed. The cross section form of semifilled protective culvert is given. The calculation method of anti-floating design of protective culvert in immersed area is discussed.
