| Abstract: | The 27m height water tower was built in 1934 Water tank on top of the water tower is supported by use of twelve reinforced concrete pillars At collapsing side,the blasting cuts with various heights are formed in 7 pillars At opposite side,a small cut is formed in the pillar on collapsing centreline and the throughout holes are made in the bottom of 4 other pillars These make the tower collapsed to correct direction In this paper,the calculation of blasting cut height,and the determination of blasting parameters are discussed At the same time,the safety measures taken in this project are introduced |
