摘　　要：电气化铁路既有线扩堑石方爆破 ,其爆破环境、地形地质、工程量等要比城市中的岩石爆破或基础拆除爆破复杂困难得多 ,规模大得多 ;由于有电接触网和距既有线线间距小 ,也比非电气化铁路既有线扩堑爆破复杂困难得多。针对电气化铁路既有线扩堑的特点而采取的先进实用有创造性的技术 。The blasting conditions,topography and geology of rock blasting for expanding cutting at the existing line of electrified railway are more complicated and difficult than that of rock blasting or foundation demolishing blast in cities.The engineering quantity is larger,too.As there has electrify overhead contact line and short space to the existing line,it is much more difficult than blasting for expanding cutting at non\|electrified railway.The paper introduces the practicable technology adopted in the light of the features of expanding the cutting for electrified railway existing line in order to attain the purpose of safety and rapid construction.
