摘要(Abstract)：

结合仙游车站拓堑工程,介绍了短时间、大方量、复杂环境下既有线石方控制爆破的方案及爆破参数的计算方式,该爆破方案既确保了施工安全、又满足施工进度及技术要求,达到了预期的效果。
Combined with the road cutting extension project of Xianyou railway station,it introduced the controlled blasting scheme and blasting parameter calculation mode for the stonework of existing lines under the condition of short time,a large number of rocks and complicated environment.This blasting scheme not only ensured construction safety,but also met the requirements of construction progress and techniques.The desired results were achieved.
