摘要
为避免高速公路路堑开挖中爆破对路堑边坡围岩的破坏和影响,选用大口径中深孔,采取优化装药结构及爆破参数等控制爆破技术,对济南绕城高速公路路堑开挖项目实施控制爆破,爆破结果表明,路堑边坡完整,半孔率超过90%,满足了施工进度和质量要求。
In order to avoid blasting destruction to cut slope and wall rock in the expressway cutting excavation, this paper probes into the technology of control blasting which uses heavy-caliber deep-hole and optimized powder charge structure and blasting parameters. Blasting practice indicates that, with the use of the technology, the slope is int＇act by the cutting, the semi-porous rate exceeds 90%, and the requirements on the construction speed and quality have been well met.
