试验结果表明,向土体中喷入高压气体会在土体中生成超静孔压,超静孔压大小与喷气压力相关;超静孔压较大时,土体发生气压劈裂,生成的裂隙又为超静孔压的快速消散提供了通道,大部分超静孔压在裂隙闭合前消散;随着超静孔压的消散,裂隙随之减小,但不会完全闭合,留存残余微裂隙。

补充资料：孔隙水
| 孔隙水 pore water 主要赋存在松散沉积物颗粒间孔隙中的地下水。在堆积平原和山间盆地内的第四纪地层中分布广泛。是工农业和生活用水的重要供水水源。孔隙水的分布、补给、径流和排泄决定于沉积物的类型、地质构造和地貌等。不同成因的沉积物中 ，存在着不同的孔 隙水 。在山前地带形成的洪积扇内，近山处的卵砾石层中有巨厚的孔隙潜水含水层；到了平原或盆地内部，由于砂砾层与粘土层交互成层 ，形成承压孔隙水含水层 。在平原河 流的中 、下游地区的河床 相的砂砾层中，存在着宽度和厚度不大的带状孔隙水含水层。在湖泊成因的岸边缘相的粗粒沉积物中，多形成厚而稳定的层状孔隙水含水层。在冰川消融水搬运分选而形成的冰水沉积物中，有透水性较好的孔隙水含水层。深层孔隙承压水往往远离补给区。离补给区越远，补给条件越差，补给量有限，故深层孔隙承压水的开采应有所节制。 |
