摘要
本文对冻土的施工方法即钻爆法和机械挖掘法进行了回顾，实践证明，采用钻爆法施工比使用风镐掘进速度提高４倍左右，机械挖掘法国内尚处于试验改进阶段。对目前施工中存在的问题进行了讨论。
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.
