摘要
桩式复合管棚套拱结构是一种新型结构,分析表明该结构既能发挥桩体的支护功能,降低边坡的刷方高度,又能提高套拱结构的承载力,防止管棚套拱的下沉和滑移。为地形偏压和围岩破碎软弱的隧道洞口安全进洞提供了一种好方法。
Pile type composite pipe-shed arch structure is a new type of structure, the analysis shows that the structure can play a pile supporting function, reduces the slope side of the brush height, but also can improve the bearing capacity of arch structure, to prevent the pipe shed arch of subsidence and slippage. This structure is a good choice for the tunnel entrance construction, in particular for the shallow bias terrain and weak surrounding rock section.
