Abstract: The stability on a tunnel face is of great practical significance for safe construction in tunnel engineering. In this work, an advanced three-dimensional (3D) failure mechanism is extended to the face stability analysis ...

Abstract: Three-dimensional (3D) stability of a slope subjected to seepage forces is studied in this work in light of the kinematic approach of limit analysis. The widely used horn model for 3D stability of slopes is presented and ...

Abstract: Because of the change in hydraulic gradient of a fully or partially submerged rock slope caused by a drop in the external or internal water level, enhanced seepage forces may lead to slope instability and collapse. Based ...

Abstract: During the tunnelling process of a tunnel boring machine (TBM), accurately predicting the advance rate (AR) is highly desirable for enhancing construction efficiency and safety. Inaccurate AR estimates may lead to extended ...

Abstract: In practical engineering, slopes near reservoirs are susceptible to collapse during the rising and falling of water levels, resulting in huge financial losses. Three-dimensional (3D) upper-bound analysis is an effective ...

Abstract: Although slump testing has been used extensively to assess the workability of conditioned soil in shield-driven tunnelling, this traditional evaluation method still requires many subjective descriptions. This study developed ...
