Discussion is made on the theoretical basis, methods and requirements of accelerated construction methods.

Study on fast construction technology of Dahuashui RCC High-thin Arch Dam;

Study on Fast Construction Technology for Moxi NO.2 Tunnel;

Research on Fast Construction and Numerical Simulation of Settlement for High Embankment;

Study on potential probing system for rapid construction of vertical shaft;

Analysis of the mechanical effect on rapid construction of super-long soft surrounding rock tunnel with high water content;

Concrete quick construction for shifting the temporary ship-lock to silt sluice in the Three Gorges Project;

Futhermore,the experiences of quick construction of tunnel are accumulated.

Introduce quick construction technology of reinforced concrete oblong assembly culvert following “protecting permafrost soil” principle—winter construction.

Some other construction performances and experiences are introduced and an efficienty way of reaching a high quality and speedy construction in the baserock section of the vertical shafts are also discassed.

The speedy construction with borehole, longhole drilling and blasting method at the freezing baserock section in №2 mine of Xuandong has been introduced.

It simply introduces the concept of high filling embankment,combining with engineering practice,synthetically considers high-speed construction of high filling embankment from some factors,disposal of natural foundation,padding,compaction,add-tendon soil,pouring starch to make up for better,in order to meet foundation engineering quality and demand of project time.

According to the engineering features, the key to organize a high-speed construction is to choose an appropriate scheme.

It implemented continuous high-quality and high-speed construction of vertical shaft.
