Combined with practical work the characteristics,technological principle,assembly of raise scaffold and construction speed of rail mounted electric-controlled integral climbing scaffold are introduced.

In order to improve the cut blasting rate of mine shaft deep borehole, to reduce the blasting material consumption and the circu- lated blasting operation time and to speed up the mine shaft construction speed, an applied study on the cut borehole diameter, depth, section number and initiating time difference and other parameters was conducted for the cut of two-section and three-section.

Stochastic carbonation durability analysis of pre-stressed concrete structure regarding construction error of concrete cover;

The influence of construction error such as vertical deviation of column etc,are frequently met in construction.
