青藏高原某公路高含水滑坡机理与防治方案

Mechanism of Landslide with High Water Content and Its Treatment Scheme of Highway in the Qinghai-Tibet Plateau Area

青藏高原高山垭口缓坡地带为高含水滑坡多发区。治理该类滑坡,根据滑坡性质、规模、地形地貌、公路与滑坡的位置关系,采用简易盲沟、渗沟及集水井、仰斜排水孔等措施尽快排出滑体地下水,同时结合公路边沟、涵洞等设置完善的地表排水体系,减少地表水的不利影响,可以达到治理滑坡,稳定路基的目的。

Landslide with high water content frequently occurs in alpine gentle slope zone Qinghai -Tibet Plateau. To control such kind of landslides, according to the characters, form, position relations between roads and landslides, we should use blind ditches, seepag inlet wells, upward oblique unwatering holes to drain the underground water of landslides. time, lateral ditches, culverts, and other measures for draining ground water are also used. these landslides could be treated and the substructures could be stabilized. scales, of the land- e ditches and At the same Afterwards,these landslides could be treated and the substructures could be stabilized.
