Based on the practice of safe monitoring in temporary ship lock and ship lift of the Three Gorges Project during its rock excavation by blasting, several problems related to blasting excavation are overviewed, such as the choice of blasting method and procedure in accordance with the analysis on blast induced damage zone during excavation of rock foundation, the control of blast vibration on the rock slope and the dividing pier between temporary ship lock and ship lift. Some unsolved important problems are discussed...

Some unsolved important problems are discussed further.

根据三峡工程临时船闸与升船机岩体开挖过程中的施工期安全监测的实践, 对与围岩爆破损伤影响范围有关的岩石基础开挖中的合理爆破方式与程序选择、岩质高边坡及中隔墩的爆破振动控制等几个与爆破开挖相关的主要问题作了概括性的介绍, 文中同时对一些值得进一步研究的问题作了讨论。

Basen on the criteria of the peak particle velocity(PPV) for blast-induced damage,the design approach for excavation blasting near contour of rock slope is discussed. A mathematic error existed in the equation to calculate PPV proposed by Holmberg and Persson is modified,then a new method which is both theoretically reasonable and easy to use is proposed to determine PPV. Finally,with the practical case of the rock slope excavation of the permanent ship locks at Three Gorges Project as an example,the detailed...

Basen on the criteria of the peak particle velocity(PPV) for blast-induced damage,the design approach for excavation blasting near contour of rock slope is discussed. A mathematic error existed in the equation to calculate PPV proposed by Holmberg and Persson is modified,then a new method which is both theoretically reasonable and easy to use is proposed to determine PPV. Finally,with the practical case of the rock slope excavation of the permanent ship locks at Three Gorges Project as an example,the detailed application of the modified approach is introduced,and rationality evaluation of the practical design parameters adopted at Three Gorges Project is also performed.

基于岩石爆破损伤影响范围控制的质点峰值振动速度判据,就临近岩石边坡开挖轮廓面的爆破开挖设计方法进行了探讨。修正了在国际上被广泛引用的计算质点峰值振动速度的Holmberg-Persson方法中隐含的数学错误,提出一种更具理论基础且又切实可用的确定岩石爆破中爆源近区的质点峰值振动速度衰减规律的新方法。最后结合三峡工程通航建筑物岩石边坡开挖中的工程实例对建议方法的具体应用作了介绍,并就三峡工程实际采用的爆破设计参数的合理性进行了评价。
