某公路排险工程控制爆破技术研究

Study on the Controlled Blasting Technology of a Highway Risk Relief Project

以某公路项目在施工过程中,需对挖方区域的石方工程进行爆破开挖为工程背景,针对该项目中的排险爆破区域300米范围内有道路、民房等重要保护对象等工程实际问题,在现场勘察的基础上并参照设计文件的要求,确定了爆破方案和相关爆破设计参数,采取了一定的安全防护措施,满足了项目安全生产的需求,为类似工程提供了可供借鉴的经验。

Based on the background of blasting excavation of Stonework in excavation area during the construction of a highway project,aiming at the practical engineering problems such as roads,houses and other important protection objects within 300m of the blasting area in the project,on the basis of field investigation and referring to the requirements of design documents,the blasting scheme and relevant blasting design parameters are determined.The safety protection measures meet the requirements of safety production of the project and provide experience for similar projects.
