摘要:
为了更好地模拟加固工程中置换洞的作用效果，本文基于FLAC3D 软件的二次开发技术，推导HTC 四参数本构模型的弹塑性矩阵表达公式，开发其软件计算模型，并结合边坡加固工程实例，建立其潜在滑体三维有限元模型，分别采用二次开发的HTC 模型及软件自带DP 模型，对边坡加固中的混凝土置换洞进行弹塑性破坏分析，通过监测点位移变化规律及塑性破坏区域扩展规律确定边坡加固后安全系数。研究发现，基于FLAC3D 软件二次开发的HTC 模型可成功应用于边坡加固分析的工程实例中，并且HTC 模型在分析混凝土破坏方面比原有DP
Abstract:
In order to better simulate the effect of the replacement hole in the reinforcement project, on the basis of secondary development technology of FLAC3D software, hte expression formula of elastoplastic matrix of HTC four-parameter constitutive model was derived, and its osftware calculation model was developed.The three-dimensional finite element model of the potential slide was established by combining with the example of the slope reinforcement engineering.The secondary HTC model and the software DP model were respectively used to analyze the elastic and plastic failure of the concret ereplacement hole in the slope reinforcement. The safety factor of the slope was determined by the variationo f the displacement and the expansion law of the plastic failure region.It was found that the HTC model baesd on the secondary development of FLAC3D software could be successfully applied to the engineering examlpe of the slope reinforcement analysis, and the HTC model was more accurate than the original DP model in the analysis of concrete damage, which could provide a reference basis for the numerical simulation sutdy of the replacement hole reinforcement.
