Simulation test and numerical simulation of anchoring effect of priestesses cable
【摘要】 预应力锚固技术在岩土工程中已得到广泛应用,对其进行的研究工作也取得了许多成果,为论证已有成果并揭示其深层次的普适的工作机理,开展了室内大型仿真试验,并以仿真试验的结果为依据,验证有限元数值分析的力学模型,之后利用数值分析进一步延伸仿真试验结果,得出了有重要实用意义的结论。
【Abstract】 Prestressed cable has been widely used in geotechnical engineering; and many achievements of its anchoring effect have been obtained. For examining those achievements and gaining further conclusions about anchoring effect of prestressed cable, indoor large-scale simulation test has been made. Based on the results from the simulation test, a mechanical model for numerical simulation is established. Further analysis of anchoring effect of prestressed cable is put forward using numerical simulation, Finally, some important and practical conclusions have been drawn.
