利用ANSYS软件建立了高压水射流切割水泥混凝土路面模型,并对该模型进行等效应力分析,再结合水泥混凝土的破坏准则得出该模型破坏所需的泵压力。实验证明该泵压力下的高压水射流完全可以切割旧水泥混凝土路面,从而表明了利用ANSYS软件分析水泥混凝土路面切割的可行性。 The ANSYS software is used to establish the high pressure water jet cutting cement concrete pavement model. The equivalent stress analysis is carried out on this model. Combined with the failure criterion of cement concrete, the pump pressure required for the model destruction is obtained. Experiments show that the pump pressure under high pressure water jet can completely cut the old cement concrete pavement, which shows the use of ANSYS software analysis of the feasibility of cement concrete pavement cutting.
