500kV高压线下深孔路堑爆破安全控制技术

在京珠高速公路江夏段500kV高压线下的路堑开挖深孔爆破的工程实例中，通过选用合理的爆破方案及爆区规划，针对复杂环境采取了一系列的安全控制技术，有效地控制了飞石和爆破地震的危害，同时也保证了边坡的平整度和稳定性。

Safety Control Technology of the Cutting Deep - hole Blasting Under 500 kV High- Tension Line

In the living example of the deep-hole blasting engineering for the cutting excavation under 500kV high-tension line at the section of Jiangxia of Jingzhu Expressway, a series of safety control techniques is adopted in view of the complicated surroudings. The hazards of flying stones and blasting earthquake are effectively controlled by means of the rational blasting program and plan of the blasting area, meanwhile, the stability and the levelness of the slope are ensured.
