【摘要】 隧道在爆破过程中对地表建筑物的影响很大,对其危害往往估计不足,从单个炮孔地表水平和竖向震速对比、地层弹性模量的变化对爆破震速的影响分析、岩石容重对爆破震速的影响分析、炮孔埋深对爆破震速的影响分析等几方面进行阐述,从中得出一些基本规律,对实际工程提供一些借鉴。更多还原

【Abstract】 The tunnel during the blasting process has a great influence on the building on the ground; its hazards are often underestimated. The article expounds on the following aspects, such as the contrast to the horizontal and vertical earthquake-speed on the surface in a single hole, the impact analysis of the elasticity modulus of rock changes to blasting speed of earthquake, the impact analysis of the rock density to blasting speed of earthquake, and impact analysis of the hole depth to blasting speed of earthquake. Some of the basic regulations can give a number of reference works to the actual engineering.更多还原
