摘要
针对工程材料的非线性问题,首先对数值模拟进行概括性分类总结并对其发展趋势进行简要分析,在此基础上,结合具体工程实例,就非线性问题的数值软件选取有关内容进行详细分析。根据分析结果,数值模拟的发展趋势为:多相及多物理场耦合、计算方法耦合以及二次开发数值模拟;数值软件选取时的主要考虑因素为:实际工程地质概况、研究内容及目的、与其他研究手段相对应、研究对象及行业领域、其他因素(具体因素);测点、测线的设置应遵循的原则有:以研究内容、对象及目的为依据、具有一定的区域代表性或宏观代表性、避免重复设置、差异性设置;测点数据呈现出较强的规律性,并与相关论文结论一致;数据规律印证了本次对于软件选取、模型建立、开挖模拟以及测点布设的相对正确性与合理性;所得结论具有一定的宏观代表性,可为相关非线性问题的数值软件选取及建模过程提供参考。
In view of the non-linear problem of engineering materials,firstly,the numerical simulation was classified and summarized,and its development trends were briefly analyzed.On this basis,combined with specific engineering examples,the selection of numerical software and the related contents were analyzed.According to the analysis results,the development trends of numerical simulation are:multiphase and multi physical field coupling,calculation method coupling and numerical simulation based on secondary development.The main factors to be considered in the selection of numerical software are:actual engineering geology,research content and purpose,corresponding to other research methods,research object and industry field,and other factors(specific factors).The principles that should be followed in the setting of measuring points and lines are:based on the research content,object and purpose,with certain regional or macro representativeness,avoiding repeated setting and differential setting.The datas show a strong regularity and are consistent with the conclusions of related papers.The relative correctness and rationality of software selection,model establishment,excavation simulation and survey point layout are confirmed by data laws.The conclusions obtained are representative and can provide a reference for the selection of numerical software and the modeling process of nonlinear problems.
