Frost heave and freezing processes of saturated rock with an open crack under different freezing conditions

Zhitao LV, Caichu XIA, Yuesong WANG, Ziliang LIN

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 4,   Pages 947-960 doi: 10.1007/s11709-020-0638-z

Abstract: Numerical results show that a frozen shell that blocks the migration of water in crack to rock developsHowever, the migration path of water in crack to the unfrozen rock under freezing front exists underThe freezing process and permeability of rock together determine the migration of water in crack andThe frost heave modes of crack in rock with low or high permeability are similar under uniform freezingTherefore, the freezing condition and rock permeability determine the frost heave of rock with crack

Abstract: When they were un-watered, their integrity was maintained completely, and their interior rock surfacesSpecifically, a three-point bending test is used to form a tensile crack in a rectangular rock specimendead load test for the specimen immersed in initially weak acid water is used for self-healing its crackThe new minerals would be able to infill the cracks and then heal the crack within a few years.Once the crack is self-healed, the rock can regain its strength and integrity.

Frontiers of Structural and Civil Engineering 2007, Volume 1, Issue 1,   Pages 63-70 doi: 10.1007/s11709-007-0006-2

Abstract: Utilizing the obtained load against crack opening displacement curve, the value of G at any crack extensionas well as the change of G with the crack extension is examined.It is found that G will firstly increase with the development of crack and then stay constant once theinitial crack tip opening displacement reaches the characteristic crack opening displacement w0.The results reveal that the values of G of different specimens at any crack propagation are strongly
