本文针对城市高架桥爆破拆除的长距离、长延时，目前只能采用非电起爆网路进行起爆的现状，研究了多发并联起爆网路的接力点雷管延期特性，提出了并联后的接力点起爆时间期望值的简易计算公式。针对不同规模的非电起爆网路提出了相应的可靠度标准，研发了既可保证高架桥倾倒过程不发生侧翻又能提高接力点起爆可靠度并可无限分段的复式交叉接力起爆网路，并推导了其起爆可靠度计算公式。相关成果为高架桥拆除爆破起爆网路设计提供了科学依据。

Non-electric initiation system was the only initiation system for viaduct blasting de-molition. Aimed at the application actuality,the relay point characteristic of multiple parallel detonator initiation system was studied in the paper,and the simple formula for mean value of the relay point initiation time was put forward. Reliability standard for non-electric initiation system of different scale was established. Duplex-cross non-electric initiation system was in-vented,which not only can avoid side roll in the viaduct collapse process,but also can elevate the reliability of the relay point. Research achievements can provide theoretical basis for viaduct blasting demolition initiation system design.
