The Demolition Blasting of Twenty-one Stories Building with Entire Reinforced Concrete Shearing Wall Structure

摘要

In the linght of an engineering practice on demolition blasting of Twenty-one stories building with entire reinforced concrete shearing wall structure, this paper introduces in detail the pretreatment methods of shearing walls which are the main bearing structures of the building,and procedures to ensure the building stability by mechanic analysis after shearing wall pretreatment. The technology of drilling longitudinal deep-holes through shearing walk was applied and safety , economy and good demolition were all ensured.
