Development and validation of a TBM cutterhead jamming risk criterion based on Platts theory: A case study of the tunnel in Xinjiang, China
During the excavation of a tunnel in Xinjiang, China, using a gripper TBM, four cutterhead jamming incidents occurred in soft rock and fault zones, delaying progress. Accurately predicting cutterhead resisting torque is critical for assessing jamming risks in remaining sections. To address the…

Nonlinear finite element assessment of an offshore wind turbine ring-flange joint under adjacent missing-bolt configurations
Bolted ring-flange connections are critical to the structural integrity of wind-turbine towers, while the absence of several adjacent bolts can significantly alter joint clamping and load-transfer mechanisms. This study presents a nonlinear finite element assessment of a full ring-flange connection…

Center point matching network based on multi-coverage templates for high-resolution satellite orthorectification
High-resolution (HR) satellite images are provided with rational polynomial coefficients (RPCs) that map ground coordinates to image space. However, initial RPCs are derived from approximate models and contain geometric errors. To correct these errors, accurate matching of ground control point…

Performance research and verification of micro aggregate concrete suitable for structural model making
Micro-aggregate concrete (MAC), characterized by low elastic modulus and low strength, is widely used in scaled models for shaking table tests. In this study, MAC was prepared using coarse sand with a fineness modulus of 3.6 and its mechanical properties, carbonation depth and steel reinforcement…

Prediction of soft ground settlement using drone-LiDAR surveys
Construction on deep soft clayey ground often experiences significant consolidation settlement. Preloading accelerates this process and is typically monitored using settlement plates (SPs). However, traditional methods lack spatial coverage, failing to capture localized settlement variations. This…

Length calculation of the negative skin friction zone of rigid pile in composite foundation based on double equal settlement surface model
Installing a cushion layer atop rigid pile composite foundations leads to the formation of a negative skin friction (NSF) zone along the upper portions of the piles, thereby reducing the bearing capacity and posing potential risks to structural safety. Based on the double-equal-settlement model of…

Computational modelling of thermo-mechanical coupled brittle fracture for rocks using phase-field method
Thermally-induced rock deformation and fracture represent critical challenges in geotechnical engineering applications such as geothermal extraction and nuclear waste storage. This paper proposes a thermo-mechanical coupled phase-field model (PFM-TM) for simulating thermal cracking in brittle…

Differentiated hydrodynamic assessment of pluvial and fluvial flooding in the downstream Periyar catchment under return period based scenarios
Flooding poses significant challenge to urban communities, particularly in tropical regions prone to extreme weather. While most studies analyse pluvial and fluvial impacts separately, hydrodynamically differentiated assessments of the two based on a validated historic compound event remains…

Theoretical analysis of seepage field in two supported circular tunnels within anisotropic ground
An alternative analytical solution to calculate the seepage field in two supported circular tunnels within a saturated ground is proposed, taking into account the interactions between two neighboring tunnels, rock-support, and anisotropy of permeability. The anisotropic problem is equivalent to the…
