为探明ABAQUS软件在模拟重力坝静力分析中的应用,以流体力学和ABAQUS相关理论为依据,通过对重力坝位移、应力、抗滑稳定的模拟分析,探索了该软件在重力坝静力分析中的应用。结果表明:在坝顶处,顺河向位移最大,移动0.10cm,整体位移并不大;坝体的最大压应力出现在坝趾处,坝踵没有出现拉应力,坝趾的压应力1.55MPa小于基岩的允许压应力30 MPa,坝体总体处于压应力状态。坝体的受力满足重力坝的应力控制标准,也符合工程实际。在折角处的应力分析中,折角处产生1.28 MPa的压应力,小于混凝土的抗压强度24.1 MPa。通过抗滑稳定分析,计算得出安全系数大于3,抗滑稳定性也符合要求。由此可知,ABAQUS软件在模拟重力坝静力分析中是可行的。该研究结果将有助于ABAQUS数值模拟技术在重力坝分析中的应用,亦有着重大的实践意义和学术价值。
In order to prove the application of ABAQUS software in the static analysis of gravity dam, based on the theory of fluid mechanics and ABAQUS, through the simulation analysis of gravity dam displacement, stress and anti-slip stability, Analysis of the application. The results show that: at the crest of the crest, the displacement along the river is the largest, with the displacement of 0.10 cm, the overall displacement is not large; the maximum compressive stress of the dam appears at the dam toe, and no tensile stress occurs at the dam butt. The compressive stress of the dam toe is 1.55 MPa Less than the allowable stress of bedrock 30 MPa, the dam body is in a state of compressive stress. The dam body’s stress meets the gravity dam’s stress control standard, also conforms to the project actual. In the analysis of the stress at the corner, the corner has a compressive stress of 1.28 MPa, which is less than the compressive strength of concrete of 24.1 MPa. Through the anti-skid stability analysis, the calculated safety factor is greater than 3, anti-skid stability also meets the requirements. From this we can see that ABAQUS software is feasible in simulating gravity dam static analysis. The results of this study will be helpful for the application of ABAQUS numerical simulation technology in gravity dam analysis, and also have great practical and academic value.
