Introduction Reinforced concrete is one of the most used materials in civil engineering structure currently.
Its durability is a major factor in the relationship between life of the civil construction and construction efficiency.
In marine and offshore engineering, saline zone engineering and northern road and bridge engineering using deicing salt, the invasion of the chloride ion or permeability is the main cause of concrete reinforcement corrosion [1].

So the blasting vibration controlling is a very important task in the field of disaster prevention and mitigation engineering[2].
Combined with the engineering practice and experience, blasting aperture D takes 40mm, hole deep L takes 1.8-2.2m, and hole spacing a is 400mm.
This is a controversial question in the engineering area[12].

This high intensity winds with both horizontal and vertical flow components in the low height range above ground level, are extremely destructive for civil structures, such as R.P.
This challenging problem has drawn more interests of both civil engineers and research scientists, and researches focusing on thunderstorm downdraft have been continually conducted by employing both test and numerical tools.

Since the karst area usually develops a lot of unfavorable geological problems, such as karst cave, corrosion fissures and karst grooves, etc., it is difficult to carry out civil engineering construction.
With the intensification of urbanization and the increasing investment in infrastructure in China, it is inevitable to come across some construction problems in karst region, one of which is the construction of super-large diameter rock-socketed piles which is widely used in civil engineering in kast region such as urban elevated bridges, highway bridges, railway bridges, and so on.
