一种新型爆破工艺，需要采用不可压缩介质作垫层，利用炸药的爆炸作用对粘土进行挤压，形成地下空间。

There is a new blasting technology which utilizes the explosion effect of the explosive to compact the soil to form the underground space with the non-compacted material as the cushion.

从新的连续介质模型出发，导出不可压缩牛顿流体在各向同性多孔介质中流动的渗流基本方程。

Then the fundamental equations of the incompressible Newton fluid flowing in the isotropy porous media are derived according to the new continuum model.
