Analyses air current status in kiln, fix quantify discusses deflexion magnetic core sintertemperature curve, analyses reason of frequent appear sinter erect crack and bring forward resolve measures of erect crack, using by parting mechanism of deflexion magnetic core,hydromechanics principle,theory of deflexion magnetic core temperature rise and eject glue.

Dynamic analysis of nearly horizontal rock slopes with vertical cracks;

Analysis of and counter-measures for vertical cracks commonly seen in piers and abutments;

Analyzing the cause of vertical cracks for thin-wall abutment shaft,the paper proposed the protective measures for reference.

This paper analyzes the causation of the vertical rifts in the concrete wall against water wave of the first stage construction of the Songgan Dike in Tonghe County and poses the prevention measure.

But as the phenomena of rupture at vertical of the high-rise building during its demolition by controlled blasting appeared,this problem was analyzed in the paper,and the compressive stress,shearing force and bending moment were calculated and verified as emphasized,the causation was discussed by carrying capacity of the component when demolished.
