Table 1: Comparison of the Past Cases and Present Case.

Cases	Blasting scheme	Advantages	Disadvantages
The past cases	Blasting demolished separately one by one	Low risk, don’t consider the interaction among the various architecture structures.	Low efficiency, construction period extended.
The present case	Blasting demolished in the same time	High efficiency, construction period shortened.	High risk, the collapse sequence, direction, scope of the dismantled building must be accurately controlled.
