某公路路线沿高山对峙,岸坡陡峻,沟谷纵横,山坡为崩塌附落堆积的岩堆体覆盖,呈中密松散体状;表层地质岩性为第四纪坡残积块碎石土,下部为硅质灰岩石英砂岩,沙质岩夹炭质页岩及泥岩。岩石地段大多节理裂隙发育,破碎松散,有的地段地下水丰富,水文地质条件复杂,为滑坡、坍滑多发地区。 A highway route along the mountain confrontation, steep slope, vertical and horizontal valleys, slopes for the collapse of the accumulation of rock pile body covered, was in the mesoluy loose form; surface geological lithology Quaternary slope residual block gravel soil, the lower part of Siliceous limestone quartz sandstone, sandstone sandstone and carbonaceous shale. Most of the fractured rock joints developed, broken loose, and some areas rich in groundwater, hydrogeological conditions are complex, landslides, slump prone areas.
