摘要(Abstract)：
三峡三期下游围堰爆破拆除网路运用了非电复式交叉接力起爆网路。本文介绍了该工程起爆网路的设计,定量分析了单起爆点起爆同双起爆点起爆及单式加强网路、复式加强网路同复式交叉网路起爆可靠度差异,并建立了数学计算模型,供同类工程借鉴。
The non-electric double crossover relaying initiating network has been used in blasting demolition of the 3rd stage downstream cofferdam of Three Gorges.In the paper,the design of the initiating network for the engineering was introduced.This was followed by comparison of the reliability of different initiating networks,including single initiating spot and double initiating spots,single fortified initiating network,double fortified initiating network and double crossover initiating network.And the mathematic calculating models of these initiating networks were founded.These can be used as a reference for similar projects.
