以含有不同长度、深度裂纹(不同拘束)核电主管道为研究对象,通过质量加速度施加法,分别对不同拘束下核电主管道施加5个地震烈度和3个实际地震的竖向地震载荷,并基于一种实际结构拘束相关断裂韧性的确定方法,对其拘束相关断裂韧性进行计算,系统研究不同竖向地震载荷下不同拘束核电主管道拘束相关的断裂韧性。结果表明,在相同的拘束下,裂纹开动力曲线随着地震烈度的增大而向左平移,拘束相关断裂韧性逐渐降低。随着裂纹长度的增加,地震烈度对拘束相关断裂韧性的影响变得更加明显;随着裂纹深度的增加,地震载荷对拘束相关断裂韧性的影响首先变得明显,然后又变得不明显。不同拘束下,实际地震载荷对拘束相关断裂韧性的影响趋势与地震烈度相同,且与震级和地震加速度时程曲线均有一定关系。
Considering cracks of various length and depth (various constraints) on the nuclear power main pipeline as the research object
through the mass acceleration application method
applying vertical load of 5 earthquake intensities and 3 real earthquakes to the nuclear power main pipeline under varying constraints respectively
and based on a method to determine the constraint related to fracture toughness of the actual structure
the calculation of constraint related fracture toughness was performed
the various constraint under various vertical earthquake loads related crack toughness was systematically studied.The results show that under the same constraint
the crack opening force curve shifts to the left with the increase of earthquake intensity
and the constraint related fracture toughness decreases gradually.With an increased crack length,the effect of earthquake intensity on constraint related fracture toughness becomes more obvious.With an increased crack depth
the effect of earthquake load on constraint related fracture toughness firstly becomes obvious
and then becomes insignificant.Under different constraints
the influence trend of the real earthquake load on constraint related fracture toughness is the same as that of the earthquake intensity
and has a certain relation with the magnitude and earthquake acceleration time history curve.
