已经尝试通过利用累积的电子数据来提高建设项目的运营效率，并针对灾害后的估计损失规划应对对策，这构建了一个数字孪生模型，可以在网络空间中再现物理空间，并将网络空间模拟结果反馈到物理空间。然而，这种模拟的应用是有限的，除非数字模型可以自动构建的数据。在这项研究中，我们开发了一个程序，利用数据处理平台来读取，转换和整合数据，以创建具有通用数据结构的中介数据。该介导的数据可用于构建各种数值分析的分析模型。利用所开发的程序，以地面调查获得的钻孔数据为基础，建立了作为中介数据的三维地表网格模型。每个网格点都有土的基本材料参数，这些参数是根据钻孔数据和其他调查报告估计的。每个网格点都有一般的岩土参数，可以很容易地转换为三维有限元模型。当增加或改变钻孔数据时，分析模型可以几乎没有成本地更新，而手动创建模型将是非常昂贵的。
There have been attempts to improve the operational efficiency of construction projects and plan response countermeasures for estimated damage following disasters through the utilization of accumulated electronic data, which constructs a digital twin that can reproduce a physical space in cyberspace and feedback the cyberspace simulation results to physical space. However, the application of such simulations is limited, unless numerical models can be automatically constructed from the data. In this study, we develop a program that utilizes a data processing platform to read, transform, and integrate data to create mediated data with a common data structure. This mediated data can be used to construct analytical models for various numerical analyses. Using the program developed, a grid model of 3-D ground surface as the mediated data was constructed based on borehole data obtained through a ground survey. Each grid point has basic material parameters of soil, and these parameters are estimated from borehole data and other investigation reports. Each grid point has general geotechnical parameters and can be easily converted to a 3-D finite-element model. When the borehole data is added or changed, the analytical model can be updated with almost no cost, whereas it would be very costly to create the model manually.
