摘要
大型复杂滑坡是山区公路边坡开挖颇为棘手的防护对象。杭金衢高速公路K103滑坡是一个典型的潜伏型岩质滑坡,体积约1.60×106m3,其成灾机制较为复杂,受公路运营条件限制,工程治理颇为棘手。通过GIS与钻孔分析,并结合定量评价,确定滑坡蠕动状态,为大型复杂滑坡制定了综合治理对策,颇值得工程借鉴。
Complexly huge landslide is a kind of intractable objiect to treat with on mountainous highway construction. K 103 slope is one of typically latent rock landslide on Hang-jin-qu expressway. Its volume is about 1.60 × 10^6m^3, and its geology condition is quite complicated. Treament schemes against landslide is intractable to be made for its constant flow of traffic on road. Deformation stage of landslide and sliding condition are both made conclusion by analysis of boring holes with GIS and 2D LEM calculation on slope stability. Comprehensive treatment countermeasures has been taken, and its achieved experience should be shared.
