This study investigates the coupled soil deformation and pore fluid flow in saturated clay around a cylindrical excavation, utilizing finite element analysis Modified Cam-Clay constitutive law. Validation of numerical model precedes parametric study, assessing volume change effects various parameters on wall ground deformations, stresses, water pressures, hydraulic gradients. Results underscore significance parameters, particularly Kappa value (κ) influencing horizontal displacements properties impacting settlements basement heave. Retaining length minimally affects stresses but crucially influences from excavation base. Wall thickness significantly reduces displacements, with added settlement benefits, while constructing bottom deck substantially mitigates displacements. thorough advances understanding soil-structure interactions, offering vital insights for engineering practices concerning excavations soft conditions.

Dynamic risk assessment is a pivotal tool for enhancing construction safety and minimizing the potential partial failure during deep extensive excavation projects. To enhance efficacy of dynamic in excavation, this study introduces novel model designed to evaluate instability excavations. It comprises factor selection identifying most pertinent factors an gauging extent throughout process. Then, was deployed Anshan Road Station Qingdao Metro. pinpoint with pronounced impact on instability, employed, yielding comprehensive evaluation index system. For real-time risk, monitoring data were used as primary source evidence. A comparative analysis involving actual predictions from conventional RBF back propagation neural networks performed. The outcome underscored superior accuracy predictive capabilities model. offers ability dynamically associated excavations featuring combination soil rock. can serve valuable methodological tool, furnishing essential support systematic prevention mitigation disasters.
