数据分析技术在特高压直流工程施工中地质灾害预警的应用研究

Application research of geological disaster early warning in the ultra-high voltage DC project construction based on data analysis technology

昌吉-古泉±1100kV特高压直流输电线路工程,以18、19标段作为研究区。对研究区沿线遥感影像数据、地质灾害数据、现场勘查数据和国家气象数据进行收集整理。通过数据分析,确定对输电线路造成威胁的地质灾害点,划分为低、中、高3个等级。建立结合降雨数据的地质灾害预警模型,进行雨量计算,并分析预警模型与地质灾害风险等级的关系。将地质灾害预警信息按照红、橙、黄、蓝4个等级进行预警,为特高压的安全施工提供一定的参考。

Changji to Guquan ±1100 kV ultra-high voltage DC transmission line project,with 18 and 19 sections as the research area.The remote sensing image data,geological hazard data,on-site survey data and national meteorological data along the research area are collected and sorted.Through data analysis,the geological hazard points that threaten the transmission lines are classified into three grades: low,medium and high.The early warning model of geological disaster is established based on rainfall data,rainfall calculation is carried out,and the relationship between the early warning model and the risk level of geological disaster is analyzed.The geological disaster warning information is carried out according to the four levels of red,orange,yellow and blue to provide certain reference for the safe construction of ultra-high voltage.
