“…Many new methods have been emerging and tentatively used in geotechnical engineering to analyze and evaluate the monitoring data so that more and more geologic information can be got with the development of intelligence science and mathematics theory. Then, the new geological defects, e.g., joint fissures and faults and environmental induced geologic information can be collected into the database and finally mapped into the numerical model with the mapping method in [ 5 ], which will not be repeated here.…”

“…The method to reconstruct and update your model with new monitoring information is the core step in our platform. In the method, real-time restructured information is mapped into the dynamic numerical simulation model and updating information into the database, rather than visual management in the conventional 3D model [ 5 ]. Mapping method describes how the excavation progress and geometrical information of each separated item project should be mapped to the numerical model.…”

“…Currently, there are mainly three methods of mapping large-scale slope safety and hazards: qualitative methodologies, statistical methodologies, and geotechnical model-based methodologies [ 2 ]. But, research work pays more attention to the static evaluation method at a certain moment, for example, general limit equilibrium method and finite element method [ 3 , 4 , 5 ], probabilistic stability analyses [ 6 , 7 ], and deterministic analyses [ 8 , 9 ]. Generally, previous simulations have commonly failed to consider the time-varying changes in geological and construction conditions.…”

“…A multi-method approach combination of geotechnical field and laboratory works, GIS, and mechanical stability analysis for the stability assessment of slopes is presented [ 21 ]. Visualization technology and the safety information model are also used in construction safety evaluation [ 5 , 22 , 23 ]. BIM (Building Information Modeling) technology has been used in construction safety management research for the whole life cycle [ 24 ].…”

Geology uncertainties and real-time construction modification induce an increase of construction risk for large-scale slope in hydraulic engineering. However, the real-time evaluation of slope safety during construction is still an unsettled issue for mapping large-scale slope hazards. In this study, the real-time safety evaluation method is proposed coupling a construction progress with numerical analysis of slope safety. New revealed geological information, excavation progress adjustment, and the support structures modification are updating into the slope safety information model-by-model restructuring. A dynamic connection mapping method between the slope restructuring model and the computable numerical model is illustrated. The numerical model can be generated rapidly and automatically in database. A real-time slope safety evaluation system is developed and its establishing method, prominent features, and application results are briefly introduced in this paper. In our system, the interpretation of potential slope risk is conducted coupling dynamic numerical forecast and monitoring data feedback. The real case study results in a comprehensive real-time safety evaluation application for large slope that illustrates the change of environmental factor and construction state over time.

This paper proposes a framework to identify geological characteristics (GC) based on borehole data and operational data during shield tunnelling using a fuzzy C-means algorithm. The proposed fuzzy C-means model was established by integrating the K-means ++ algorithm into the fuzzy set theory. The identified factors for GC include advance rate, cutterhead rotation speed, thrust, cutterhead torque, penetration rate, torque penetration index, field penetration index, and specific energy. Principal component analysis was employed to reduce the dimensions of these factors. The first six principal components were employed to analyse the GC and establish the input data set in the fuzzy C-means model. The types of GC were determined based on elbow method, silhouette coefficient, fuzzy partition coefficient and the geological profile from borehole data. The proposed approach was validated by a case of Guangzhou intercity tunnel construction. The results present that the proposed fuzzy C-means model can effectively determine GC and provide membership to reveal the proportion of hard rock.
