松软地层水平管棚工艺参数的研究

Study on the art parameters of horizental barrel vault advanced support in the soft rock

通过对管棚的几何关系和承受的地压分析 ,应用编程计算 ,可得到不同工程条件和地质条件下管棚的长度、管径、间距、仰角和掘进步距等施工参数的计算值 .按此方法指导的水平管棚设计施工在北京地铁复八线和热力管道工程中取得了良好的效果 .

The values of the barrel length, barrel diameter, barrel space, slope angle and tunneling space in various engineering conditions and geological conditions can be calculated from the program by geometric analysis and geostatic analysis to the barrels. Based on this method, the design and construction of barrel vault advanced support in line Fuxingmen to Bawangfen of subway and the heating pipe in Beijing got a perfect result.
