Groundwater Environmental Effects Risk Management in Mountain Tunnel Construction: An Emergency Response System Based on Fuzzy Two-Dimensional Cloud Probability Model

Abstract

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 during tunnel construction and making rational emergency response decisions are crucial. Considering the diversity, complexity, uncertainty, and dynamics of groundwater environmental effects, this study develops a risk emergency response system for tunnel construction groundwater environmental effects. 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 bases and multi-source data fusion techniques. Finally, based on the theories of fuzzy mathematics and two-dimensional cloud models, along with probabilistic algorithms, 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, facilitating engineers and decision-makers in strengthening human-centered emergency responses.
