frost heaving pressure [地质] 冻胀力
Pressure relief holes give a big help to decrease the frost-heaving pressure and excavate soil enclosed by frozen curtain.
泄压孔的设置可以有效减小冻胀压力，并有利于冻土帷幕内土体的开挖；
The larger the confining pressure, the larger the frost heaving strain and stress.
围压越大，冻胀力和冻胀应变越大。
The results indicate that using releasing-pressure holes can sharply reduce the horizontal frost-heaving force aga...
