| Abstract: | Based on the status analysis on applicability of rotary drilling technique in home and abroad, through amount of engineering examples and spot practice, the author researched the applicability of rotary drilling technique and compared to normal ＆ reverse circulation drilling. The research includes construction efficiency, construction quality, applicability range, construction cost, et al. In the last, the author suggested that optimum combination of the two costructuion methods should be applied in especial projects construction. |
