摘要
连霍公路(甘肃省临泽至清水段)建设项目地质灾害危险性评估,着重对发育在公路沿线一定范围的泥石流(洪水)、土壤盐渍化(盐胀变形)、风蚀沙埋等较为特殊的主要地质灾害类型,从其发育特征、分布规律及成因进行了深入分析,结合地质灾害稳定性、易发性及危害程度进行了危险性现状评估 为拟建项目防治地质灾害提供了依据。
Linze\|Qingshui free way is a development item in the west of Gansu province. By analysisng the hazard type of debris flow(flood), soil salinization (bulge deformation), wind erosion and sand burial along the highway as well as the developing characteristic, distribtuion regulation and original cause, the stability, liability of development and danger degree of these geological hazards were assessed. This provides a basis for controlling the geological hazards involved with this item and also is of significance for assessment of risk of geological hazards in construction land in the future.
