本文选取了青岛地铁3号线万年泉路站至李村站区间为研究对象,沿线下穿和旁穿许多住宅区、高层建筑和构筑物及一些重要的管线等,所穿越的围岩为花岗岩,采取的施工方法主要为钻爆法。为研究爆破施工对地表建筑物的影响,进行了爆破振动监测。研究结果表明,设计给出的爆破震动方案实际可行,施工过程中所产生的爆破震动速度处于安全可控范围之内。
This article chooses the Wannianquan Road Station to Licun Station of Qingdao Metro Line 3 as the research object, and many residential areas, high-rise buildings and structures and some important pipelines are worn and laid down along the line. The surrounding rocks are granite , The construction method adopted is mainly drilling and blasting method. In order to study the impact of blasting construction on the surface buildings, blasting vibration monitoring was carried out. The results show that the blasting vibration scheme given by the design is practically feasible and the blasting vibration velocity generated during construction is within the safe and controllable range.
