地质灾害对湖北电网安全运营的影响及治理研究

基于对遍布湖北省内100多个可能有地质灾害隐患的变电站、输电线路的安全运营情况进行调查，总结出湖北省110 kV以上的变电站、输电线路地质灾害的主要类型和分布特征，并分析了地质灾害的主要成因。以十堰500 kV变电站工程为例，通过极限平衡法和FLAC3D数值模拟对滑坡稳定性进行分析，提出了治理方法，并对治理结果进行稳定性验算，提出了湖北电网地质灾害的治理措施，为湖北电网的安全运营提供参考。

Study on Influence of Geological Disasters on Safe Operation of the Power Grid in Hubei and the Control Measures

Based on the investigation on safe operation of more than 100 substations or transmission lines which may have hidden trouble caused by geological disaster across Hubei Province, the main types and distribution characteristics of the geological disasters harmful to the substations or transmission lines, which is 110 kV or above, were summarized, and the causes thereof were analyzed. Taking the 500 kV Shiyan Substation project as an example, the landslide stability was analyzed by limit equilibrium method and FLAC3D numerical simulation, through which the control measure was proposed, then the control result was checked. At last, the measures controlling the geological disasters harmful to the power grid in Hubei were summarized, providing reference to its safe operation.
