Abstract:
The large surge shaft of Xi’ergou Hydropower Station constructed with open caisson. The open caisson has a large structure and is located in complex strata of pebbles gravel, so it used explosion method to solve the problem of the subsidence blocked in sinking construction according to the shaft lining sinking by vibration made by the shock wave overpressure’s decrease and increase alternatively. Rely on the project of Xi’ergou, in case of the damage of open caisson, it got the maximum amount of explosive allowed is 171.13kg and 74.87kg by calculating the peak value of overpressure according to theoretical analysis and numerical simulation. Using explosion method to help sinking by small amount of explosive can complete the construction tasks by the premise of the guarantee of construction safety in practical engineering.
