【摘要】 由于许多工程受地理空间的限制以及安全等各方面的需要,随着人类社会的发展和科技进步,地下洞室工程已越来越多地应用在社会国民经济建设的各个领域,如水利水电工程的大型地下厂房、公路及铁路隧道、地下飞机库、地下燃油库等都属于地下洞室工程,大型地下洞室工程已成为当前岩土工程发展的前沿。这些地下洞室工程大都建在山区,工程施工往往都要采用各种爆破开挖手段。而爆破总是会产生大量的爆破冲击波和爆破振动,这些不但会危及洞室本身安全,而且还会对临近建筑物的安全有较大危害[1-21]。要对爆破振动强度及其产生的危害进行有效控制,就必须了解被保护建筑物的爆破振动危害机制,进而才能根据临近建筑物的动态响应状态及其破坏现象调查确定其爆破振动破坏判据[22-30],从而才能制定相应的爆破参数并依此进行爆破施工和爆破振动控制[6,7,11,14,15,17,26,27,31-39]。在建的漫湾水电站二期地下洞室工程,不但工程规模巨大,地质条件复杂,施工工期紧,而且紧邻正在运行的已建一期水电站工程,而该一期水电站又是云南省电网的主力电站,其安全运行事关重大,二期工程地下洞室的开挖爆破除了要保证洞室本身的稳定安全以外,还必须严保紧邻的一期水电站工程安全运行不受影响。本文结合漫湾水电站二期工程的地下洞室开挖爆破,对施工生产的开挖爆破进行了科学而严密的监测,在测得大量真实有效数据的基础上,进行了爆破影响分析和一期工程的保护措施研究以及爆破振动风险预测和分析。爆破振动分析主要成果有:(1)保护对象允许爆破质点振动速度;(2)保护对象爆破振动速度控制标准;(3)保护对象最大爆破振动加速度;(4)保护对象最大爆破振动更多还原

【Abstract】 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更多还原
