| 英文摘要 | In order to control the effect of blasting excavation on bedrock in an allowable range, safety control parameters are presented for the nuclear island foundation blasting excavation in Dalian nuclear power plant. First,, the law of peak particle velocity (PPV) is obtained from field blasting test; meanwhile, based on the velocity variation of sound wave in bedrock measured before and after the blasting, the blasting damage zone is defined in combination of the sound wave test. Second, according to the combined numerical simulation analyses of LS-DYNA and FLAC3D, the relation between PPV and the depth of the blasting damage zone is established. Finally, the safety control parameters are determined respectively, corresponding to the allowable blasting damage depth in different excavation layers, and validated by vibration monitoring during actual excavation. The presented method of determining safety control parameters for foundation blasting excavation could be referenced for other similar projects. |
