山区公路常常需要频繁跨越V型冲沟,冲沟高填路堤整体沉降、局部沉降或边坡失稳等病害较多。填料往往来源于隧道渣料,颗粒粒径大,变形复杂,且冲沟处地面坡度一般较陡,严重影响冲沟高填路基的建设和营运安全。因此,如何确保高巨粒土填方路堤的稳定性,成为山区公路修筑有待解决的关键技术问题。 Mountainous roads often need to frequently cross the V-shaped gully, embankment filled gully the whole settlement, partial settlement or slope instability and other diseases more. Filler often comes from the tunnel slag, the particle size is large, the deformation is complex, and the gully at the ground slope is generally steep, seriously affecting the gully high embankment construction and operational safety. Therefore, how to ensure the stability of embankment filled with high-grained soil has become a key technical issue to be solved in the construction of mountainous highway.
