| Abstract: | A review is made for blasting and sinking mechanized methods of frozen soils. It is found that the velocity of blasting four times as high as of sinking mechanized method. The latter is on trial in China. The present problems of sinking methods are discussed in this paper. At last the paper expounds how to improve the sinking methods. Development tendency of sinking methods of artificially frozen soils is that blasting method will be further improved and developed, and sinking mechanism will be further designed and investigated. |
