摘  要:地震多发地区通信基站的工况预测是震后通信应急保障及减灾的一项重要基础工作。针对目前基站评估仅限于基站结构等局地参数的分析方法,文章从地质地理条件等影响因素出发,通过定性的线性回归分析建模并预测震后基站失效概率。通过对预测概率分布的统计分析确定阈值为 0.4,模型检验集结果显示预测准确率为 95.2%。该结果说明,从大尺度空间、地质地理等宏观参数的设置,可以对震后基站工况进行较准确预测评估。

Abstract: The prediction of the working status of communication base stations in earthquake prone zones is an important basic work for post-earthquake communication emergency support and disaster reduction. In response to the current analysis method of base station assessment limited to local parameters such as base station structure, this paper models and predicts the failure probability of postearthquake base station through  qualitative linear regression analysis from geological and geographical factors. The threshold value of 0.4 is determined by statistical analysis of the predicted probability distribution, the results of model test set show that the prediction accuracy is 95.2%. This result illustrates that the setting of macroscopic parameters from large scale spatial and geological-geographical can be used for a more accurate prediction assessment of post-earthquake base station working conditions.

Keywords: earthquake prone area; communication base station; Logistic regression; reliability prediction
