基于层次分析法的220 kV变电站进线非开挖电力排管工程施工方案分析

Construction Scheme for Trenchless Power Piping Engineering for 220 kV Substation Incoming Line Based on Analytic Hierarchy Process

当前应用于电力电缆排管非开挖施工的主要方式有水平导(定)向钻进铺管法、气动矛铺管法、顶管铺管法、盾构铺管法等。基于系统工程理论,对上海新泽220 kV变电站进线电力电缆非开挖段这一实际工程实例,结合层次分析法(AHP)进行分析,通过理论计算选出最优施工方法。

At present,the main methods used in trenchless construction of power cable piping include horizontal directional drilling method,impact mole pipe laying method,jacking pipe laying method,shield pipe laying method,etc.Based on the system engineering theory,this paper analyzes the trenchless section of incoming power cable of Shanghai Xinze 220 kV Substation with analytic hierarchy process(AHP)and selects the optimal construction method through theoretical calculation.
