高坡脚建筑物渗流冰的防治

Prevention and cure of seepage ice on high slope foot

在北方丘陵山区、高坡脚下往往修建建筑物，由于高边坡大比降的影响，建筑物阻断了地下水原有渗透通道，成为渗透水流的出逸点，冬季则发生冰积、冰盖，致使建筑物发生冰膜或形成冰大坂，影响建筑物的正常使用，本文结合参窝地区的工程实例，介绍了暗排等办法及防治渗流水的措施。

In north hill zone, some structures are sometimes built on the high slope foot. Owing to effect of the high side slope and biggish gradient ratio, the intrinsic seepage passage of underground water is cut and the structure becomes an exit point of seepage flow. The seepage water freezes in cold winter then it becomes ice carapace and mound, and the ice film or ice slab covers on the structure, so that the structure normal use is affected. The paper introduces the measures to prevent and cure seepage water by a blind drainage, taking some projects in Shenwo reservoir area for example.
