Abstract

In response to the complex risks that disasters caused by heavy rains bring to rammed earth ancient city site. This study proposes a heavy rain risk monitoring method based on digital twin technology, and uses the risk assessment model as an important twin model for intelligent prediction, aiming to improve the efficiency of risk identification, meet the needs of high-quality decision-making, and optimize the disaster management process. First, a user-friendly digital twin monitoring platform architecture is defined to include four layers: data layer, entity layer, model layer and function layer, which work together to enhance monitoring and prediction capabilities. Then, combining the dangers of disaster-causing factors and the vulnerability of the ancient city site itself, a risk assessment model was established to predict potential risks and threats in heavy rains. Finally, the effectiveness of this method was verified through practical application in the ancient city of Puzhou. This research not only provides a comprehensive management solution for ancient city site protection and disaster prevention, but also opens up a new path for digitally driven flood disaster risk assessment and prediction.

基于数字孪生的夯土城市遗址暴雨灾害动态监测风险评估方法——以蒲州古城为例

针对暴雨灾害给夯土古城遗址带来的复杂风险。本研究提出了一种基于数字孪生技术的暴雨风险监测方法，并将风险评估模型作为智能预测的重要孪生模型，旨在提高风险识别效率，满足高质量决策需求，优化灾害管理流程。首先，定义了一个用户友好的数字孪生监测平台架构，包括数据层、实体层、模型层和功能层，这些层相互作用，增强监测和预测能力。然后，结合致灾因素的危险性和古城遗址自身的脆弱性，建立了预测暴雨潜在风险和威胁的风险评估模型。最后，通过对浦州古城的实际应用，验证了该方法的有效性。本研究不仅为古城遗址保护和防灾提供了全面的管理解决方案，也为数字化驱动的洪水灾害风险评估与预测开辟了新的路径。

期刊介绍： Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces: • the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations; • the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change; • the assessment of the mechanical and hydrological behaviour of soil and rock masses; • the prediction of changes to the above properties with time; • the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
