结合公路工程实际 ,针对具体问题提出了切实可行的施工方案 ,保证了施工工期的同时 ,降低了成本。重点讨论了爆破设计和爆破参数的确定。从爆破施工、堵塞设计、起爆网路优化等着手 ,分别对个别飞石安全距离、爆破振动安全距离和爆破空气冲击波等进行了安全验算。最后 ,给出了该设计下的爆破效果和技术经济分析 ,突出了峒室松动控制爆破方法应用在公路工程土石方开采中的高效性和经济性特点。
Combined with the actual highway engineering, put forward feasible solutions for the specific problems, to ensure the construction period, while reducing costs. Focus on the blasting design and blasting parameters to determine. From the blasting construction, the design of the blockage, the optimization of the detonating network and so on, the safety clearances of the individual flying stones, blasting vibration safety distances and blasting air shock waves are respectively checked. Finally, the blasting effect and technical and economic analysis are given under the design. The loosening control blasting method in the project is highlighted in the efficiency and economic characteristics of earthwork mining in highway engineering.
