We developed a correction model based on laboratory data, taking into account elements such as fluid density and viscosity. Our model showed an ideal accuracy and outperformed other models. When applied in real situations, it significantly reduced the differences in calculated stresses for different fracturing fluids.

We use technical methods of instrument development, calibration experiments, and numerical simulations to develop a new type of in situ stress sensor group using fiber Bragg grating (FBG) sensing technology, which can calculate the in situ stress state of surrounding rock mass by sensing the borehole wall strain. This sensor group lays an important theoretical and experimental foundation for the development and application of FBG hole wall strain gauge.

Short summary
We estimate the slip susceptibility of the faults in the Yishu fault zone based on slip tendency analysis based on coupled tectonic stress profiles. Results show that the overall stress accumulation degree is relatively low. The overall seismic risk is not high in the study area, while a transition zone of seismic risk from medium to low exists in the southeastern part of Yishu fault zone. These results provide geomechanical evidence for evaluating the regional crustal dynamics.

Short summary
To identify the boundaries and deformation distributions of the unstable areas, the results of space-borne SAR and field surveys were combined, and the spatial deformation characteristics and time evolution of the landslide were analysed. The factor inducing landslide deformation is concentrated heavy rainfall. The research results show that SAR/InSAR technology can reveal the surface deformation of a landslide body and characterize the active stage and development trend.

Short summary
We considered a translational landslide exhibiting an unusual morphology, i.e., the Wobaoshi landslide. The deformation and failure mode of the plate-shaped bodies were analyzed and investigated based on numerical simulations and calculations. The monitoring data and geomechanical model proved that the accumulated water pressure in cracks causes the plate-shaped bodies to creep. Therefore, these research findings are of reference significance for the
rainfall-induced translational landslides.
