摘要
宜万铁路白杨坪隧道DK194+039～DK193+980段岩体破碎,裂隙水、富水淤泥填充型溶腔发育。由于岩体自稳能力极差,开挖中突水、突泥时有发生,安全隐患大,开挖施工困难,为此采用帷幕注浆对围岩进行堵水、填充加固。
The Baiyangping tunnel DK193 ＋ 039 - ＋980 section in Yiwan railway develop with cracked rock, fissure water and water-rich silt-filled type dissolved cavity. As a result of ex- tremely bad self-steady ability the water inrush mud inrush oc- curred frequently during excavating, with great security risks and excavating difficulty, therefore the curtain grouting is adopt- ed for water plugging and filling reinforcement in wall rock.
