静宁至天水高速公路地质灾害危险性分区与防治措施研究

Study on geological hazard zoning and prevention and control measures of jingning to tianshui expressway

静庄高速公路地处陇东、陇西黄土高原丘陵沟壑区,黄土梁峁起伏,沟壑纵横,地质灾害较发育,分为大、中、小3个区,8个段,其中危险性大区5个段,危险性中等区1个段,危险性小区2个段。从实用性及可操作性出发,分别对区内存在的和可能引发的不同类型地质灾害提出预防和防治措施建议,为工程建设提供可靠的支持。

Static expressway is located at longdong, zhuang west gansu loess plateau hilly-gully region of loess Liang Mao ups and downs, gully aspect, geological disaster development, divided into large, medium and small three, eight segments, including five regional risk, medium risk zone 1 section, dangerous district two segments. Based on the practicability and operability, the prevention and control measures for different types of geological hazards in the region are proposed, which provide reliable support for the project construction.
