| Abstract: | In this paper, a new technique of protective layer excavation of horizontal founda- tion was expounded and applied to the construction of Lijiaxia hydropower station. The par- tition function of flexible cushion on the bottom of explosive holes was proved by experiments before explosion. New structure with air layer for explosive charges loading and the non-elec- tric millisecond difference detonating network which combines the time delay initiating were used in holes and out of holes with 753 segments making holes to blast out one by one. |
