摘要
在通电超高压线下进行路堑开挖爆破作业,必须保证高压线路和铁塔的安全,对爆破振动和飞石控制严格,爆破设计和施工难度较大。介绍了该复杂环境下控制爆破方案设计、爆破参数选取和安全防护措施;并对爆破效果进行了分析,得到了一些有益的经验。
The safety of the super-high voltage transmission line and its transmission tower must be assured, while blasting excavation of the cutting is constructed under the super-high voltage transmission line. The blasting vibration and flying rock control are also strictly required, so blasting design and implementation are very difficult. Controlled blasting design and blasting parameters choice of the stone cutting under the super-high voltage transmission line and its safety measures were introduced, and blasting effect was analyzed. Some valuable enlightenments and experiences were gained.
