水电站库岸边坡控爆整治的试验研究
|
摘要
试验结合四川乐山铜街子水电站库岸(龚咀水电站尾水岸坡)的整治,研究了保证水电站正常运行的安全标准,试验研究即发和微差延期雷管的爆破震动变化。当在水上或水下爆破时,探讨了不同距离为确保电厂机组和仪表能正常工作的爆破最大单响限制药量和不同情况合理的微差间隔时间。根据试验取得的成果,建议的爆震安全标准和采用的安全技术措施,可供类同工程借鉴。
The authors have made a study of the safety standard of assuring the normal operation of a hydropower plant, and have tested and studied the vibration variation caused by instantaneous detonator and short delay blasting on the basis of the reservoir bank slope (tail water bank slope of Gongzui hydropower plant) treatment test of the Tongjiezi hydropower plant in Leshan, Sichuan province. The authors have also made an approach to the maximum limited blasting charge for single blow and to the proper short delay spacing intervals under different conditions in different distances to ensure the normal operation of both generating units and instrument when blasting was conducted above and under water respectively. The authors have proposed both the safety criteria for blasting and the safety technical measures according to the test results, which can be used for other projects of its kind.
