摘要:
针对土木工程中地基桩强度分布不合理的问题,建立地基桩的三维物理模型,基于Simple算法,运用RNGk-ε湍流方程,结合有限体积法对控制方程进行离散,在风速10m/s的情况下,对地基桩周围绕流流场分布进行分析。结果表明,地基桩中间区域所受风力作用较大,易受损,其周围流场变化经历平稳—剧烈—平稳的过程,部分区域地基桩易受到破坏。因此,应重视加固工作,完善和发展地基桩绕流阻力特性理论,为实际工程提供参考依据。更多还原
Abstract:
In terms of the improper intensity distribution of foundation pile in the civil engineering, a 3D physical model of foundation piles was established. Based on the Simple algorithm, using RNG k- turbulence equations and finite volume method, the control equation was discretized. With the wind speed of 10m/s, the flow field distribution of foundation pile was analyzed. The result shows that the middle part of the foundation pile is greatly affected by the wind power and is vulnerable to damage, and if the surrounding field undergoes stable-fierce?stable periods, parts of field will be vulnerable to damage. It is thus important to stress the consolidation, develop the flow resistance characteristics theory of the foundation pile and provide references for the actual project.
