| Abstract: | Focused on the basic principles and methods of Controlled Blasting Open Caisson(CBOC) on weak rock mass, a case study is shown in the paper. A rein-forced concrete cylinder with 17. 5 meters of inier and 19. 6m of outer diameter. 15 meters high and about 23,000kN in weight, is successfully settled down to the right location for 12.75m through the fractured rock mass by the method of CBOC, which is desired using it for 11 times. This is shown that CBOC is one of the fast, safe and reliable methods in the installation of caisson. |
