摘要: 峡口水库发电输水隧洞进水口位置靠近坝体、厂房等建筑物,且周边岩体较为破碎。通过现场爆破振动试验制定了合理的爆破方案,并在爆破过程中实行爆破振动监测,按照监测结果及时调整爆破施工方案,达到对邻近建筑物进行保护的目的。

Abstract: As the water inlet of Xiakou reservoir tunnel lay next to dam body and structures and the rock mass nearby was broken, explosion test was carried out for better blasting scheme design. In the blasting process, vibration monitoring was adopted, and construction scheme was adjusted accordingly. As a result, the buildings around were protected from adverse influence of the blasting.
