ABSTRACT = {Concrete	structures	such	as	offshore	platforms,	costal	and	port	structures,	dams,	etc.,	are	often	submerged	
in	 water [1].	 The	 water	 within	 concreter	 pores	 or	 cracks	 has	 a	 great	 influence	 on	 crack	 propagation	
behavior [2,3].	Several	wedge-splitting	experiments	of	compact	specimens	are	conducted	with	a	designed	
sealing	 device	 to	 study	 the	 water	 effects	 on	 concrete	 crack	 propagation.	 Different	 water	 pressures	 and	
different	loading	rates	are	considered	loading	on	the	pre-crack	surfaces	and	waterproof	strain	gauges	are	
stuck	along	the	crack	path	to	observe	the	fracture	process	during	the	experiments.	Water	pressure	values	
on	crack	surfaces	are	recorded	by	diffused	silicon	water	pressure	sensors	via	the	precast	holes.	The	results	
show	 that	 the	 water	 pressure	 on	 crack	 surfaces	 accelerates	 the	 crack	 propagation	 of	 the	 concrete.	The	
critical	 value	 of	 the	 splitting	 force	 decreases	 in	 a	 shape	 of	 exponential	 curve	 with	 the	 increase	 in	 the	
external	 applied	water	 pressure.	 The	 hydraulic	 crack	 propagation	 speed	increases	 at	 the	 beginning	 and	
tends	to	reach	a	peak	value	finally.	Under	larger	loading	rate,	the	water	fails	to	fill	the	crack	and	only	the	
trapped	water	interacts	with	the	crack	surface.	The	water	pressure	is	mainly	a	parabolic	curve	distribution	
along	the	crack	path	and	the	peak	value	decreases	with	the	increases	in	the	crack	length.	The	effect	of	the	
water	 fracture	 interactions	 in	 concrete	 is	 severe	 in	 fast	 loading	 conditions	 rather	 than	 in	 quasi-static	
conditions	during	crack	sudden	opening.},
