The underground water environment in mountain tunnels constitutes a complex system. During tunnel construction, the interaction between tunnel and underground water environment can lead to chain construction accidents and environmental damage. Identifying comprehensive risks of underground water environment effects and making rational decisions are crucial. Considering the diversity, complexity, uncertainty, and dynamics of groundwater environmental effects, this study develops a risk decision support system for tunnel construction. Firstly, to reflect the complexity and diversity of groundwater environmental effects, a disaster chain is established, and two indicator systems are extracted. Secondly, dynamic datasets are generated using a combination of expert system knowledge base and multi-source data fusion. Finally, based on the theories of fuzzy mathematic and two-dimensional cloud model, along with probabilistic algorithm, this study proposes a Fuzzy Two-Dimensional Cloud Probability Model (FTDCPM) to quantify the uncertainty of groundwater environmental effects. This engineering system can provide reference in similar projects.

山地隧道施工中地下水环境影响风险评估——基于模糊二维云概率模型的动态决策支持系统


山地隧道中的地下水环境构成了一个复杂的系统。在隧道施工过程中，隧道与地下水环境的相互作用会导致链式施工事故和环境破坏。识别地下水环境影响的综合风险并做出合理的决策至关重要。考虑到地下水环境影响的多样性、复杂性、不确定性和动态性，本研究建立了隧道施工风险决策支持系统。首先，为了反映地下水环境影响的复杂性和多样性，建立了灾害链，并提取了两个指标体系;其次，使用专家系统知识库和多源数据融合相结合生成动态数据集。最后，基于模糊数学和二维云模型理论，结合概率算法，提出了一种模糊二维云概率模型（FTDCPM），用于量化地下水环境影响的不确定性。该工程系统可以在同类项目中提供参考。
