Studies On Being-influenced And Protective Measures Of One Issue Of Project By The Excavating Of Underground Hole Room

As a result of many projects geography space limit as well as security and various aspects need, along with human society's development and technical progress, the underground hole room project has more and more applied in various social economy construction domain,such as the arge-scale underground workshop in water conservancy and hydrapower project, the road and the railroad tunnel, the underground airplane hangar, underground burn the fuel depot and so on., the large-scale underground hole room project has being become the development direction of current rock- earth engineering. These underground hole room projects mostly construct in the mountainous area, the project construction often use each kind of blasting excavation method. But demolishes always can produce the massive demolitions shock wave and cause demolition vibration, these not only can endanger hole room itself, moreover also can damage the security of the neaby building [1-21]to kontrol the demolish harm and the vibration strength, we must understand the destroied mechanism of the protected building from the demolition vibration, then according to the dynamic response condition and its the destruction phenomenon of nearby building ,we can find out its demolition vibration destruction criterion[22-30],thus can formulate the corresponding demolition parameter and carry on the demolition construction and the vibration control according to this[6,7,11,14 ,15,17,26,27,28-35].The constructing second issue of underground holes rooms project of manwan hydropower station, Not only project scale is huge, geological condition is complex, the construction time is limited, moreover locate the first phased constructed hydropower station project, the first phased constructed hydropower station is the...
