摘要
某市于山溜冰场工程位于市中心于山下 ,属大跨、浅埋地下洞室 ,该工程位于闹市区 ,具有周围环境复杂、技术要求高、施工难度大的特点。为此 ,在钻爆施工过程中 ,必须采用控制爆破技术 ,一方面要尽量减少爆破振动对周围建筑物及文物的影响 ,另一方面又要控制飞石距离 ,并尽量降低爆破噪音 ,使之不影响附近居民的正常工作和生活 ,本文重点阐述了控制爆破技术在于山溜冰场工程中的应用。
The Yushan Skating Rink Project was situated at the bottom of Yushan Hill in a city's central busy region.It was a large span shallow underground cavern.The surrounding environment of this project was complex with specialities of high technical requirements and big constructing difficulties.Therefore, during the construction procedure by drilling and blasting method,the control blasting technique must be employed, not only for decreasing the influence of blasting vibration on the surrounding buildings,but also for controlling the distance of flying rocks and for lowering the blasting noise.The applications of the control blasting technique in the Yushan Skating Rink Project are expounded in detail in this paper.
