Speech Title：Research on geological hazards effect along the Anninghe fault zone at the eastern edge of the Tibetan Plateau
Abstract：Tibetan Plateau is known as the roof of theworld. Due to the continuous uplift of the Tibetan Plateau, many active fault zones are present. Theseactive fault zones such as the Anninghe fault zone have a significant influence on the formation of special geomorphology and the distribution of geological hazards at the eastern edge of the Tibetan Plateau. The Anninghe fault zone is a key part of the Y-shaped fault pattern in the Sichuan-Yunnan block of China. In this paper, high-resolution topographic data, multitemporal remote sensing images, numerical calculations, seismic records, and comprehensive field investigations were employed to study the landslide distribution along the active part of the Anninghe. The influence of active faults on the lithology, rock mass structures and slope stress fields were also studied. The results show that the faults within the Anninghe fault zone have damaged the structure and integrity of the slope rock mass, reduced the mechanical strength of the rock mass and controlled the slope failure modes. The faults have also controlled the stress field, the distribution of the plastic strain zone and the maximum shear strain zone of the slope, thus have promoted the formation and evolution of landslides. We find that the studied landslides are linearly distributed along the Anninghe fault zone, and more than 80% of these landslides are within 2-3 km of the fault rupture zone. Moreover, the Anninghe fault zone provides abundant substance for landslides or debris flows. This paper presents four types of sliding mode control of the Anninghe fault zone, e.g., constituting the whole landslide body, controlling the lateral boundary of the landslide, controlling the crown of the landslide, and constituting the toe of the landslide. The results presented merit close attention as a valuable reference source for local infrastructure planning and engineering projects.

Speech Title：Study of the soil displacement field around a laterally loaded pile based on the PIV technique
Abstract：With the development of digital image processing, an economical, accurate, and full-field image correlation technique, termed particle image velocimetry (PIV), has been used in geotechnical engineering. Yuan Bingxiang was the first to apply the PIV technique to the study of the two-dimensional displacement field of the soil around the pile. On the one hand, the variation pattern of the damage range and the influence range of the soil around the pile under different cross-sectional piles under load was successfully obtained. On the other hand, the newly developed Stereo-PIV technique was used to investigate the effect of passive piles on the deformation of the soil around the laterally loaded piles. Furthermore, the team combined the PIV technique with transparent soil to build a full 3D displacement measurement system. The internal soil displacement around the pile under lateral load was visual based on hydraulic gradient tests. The three-dimensional deformation characteristics of the soil in the zone of influence were obtained by reconstructing the two-dimensional displacement field. This study helps to better understand the interior soil behavior around a laterally loaded pile.

Speech Title：Study of the Soil Displacement Field Around a Laterally Loaded Pile Based on the Piv Technique.
Abstract：With the increase of the train speed and the proportion of high-speed railway Bridges in the line, the coupling dynamic action of earthquake and high-speed train will have a more significant impact on the dynamic response of the train-bridge system, the safety of the train operation on the bridge and the comfort of passengers, and its dynamic behavior will be more complex. Explore the coupling mechanism. It is of great significance to analyze the dynamic response of high-speed train-bridge system under earthquake action and formulate corresponding early warning measures.

Speech Title：Evaluating The Effects Of Climate Changes On Landslide Hazard Map Using Support Vector Machine (SVM)
Abstract：Landslide is a natural disaster, and 4862 landslide events reportedly occur globally between the period 2004 to 2016, which cause 55,997 fatalities. Landslide hazard is defined as landslide damaging potential to occur at a specific area, consisting of fatalities or injury, destruction of property, disruption to economic and social, or degradation to the environment. Climate change, directly and indirectly, affects the stability of single slopes, and the landslide susceptibility area may also change. It is found that there are a limited number of studies that assess the effects of climate variability on landslides, including retrospective methods and prospective modelling that use climate records and landslides. This study, therefore, tends to propose new modelling of the problem by considering climatic change influences on landslide hazard map (LHMs) in Penang Island, using Support Vector Machine (SVM). Penang Island is selected as a study area due to the frequent number of landslides reported. Furthermore, its topography contains almost 50% of the highland area, increasing the risk of landslide events. Two climate factors are selected in this study (mean annual temperature and rainfall) with 12 causative factors, which are stream power index (SPI), normalized difference vegetation index (NDVI), lithology, elevation, slope aspect, slope degree, plan curvature, land use, topographic wetness index (TWI), distance to faults, distance to river and distance to the road were used in SVM model. The climate changes of the study area are stimulated using Statistical Downscaling Model (SDSM) under RCP4.5 and RCP8.5 scenarios. ArcGIS 10.7.1 is used to integrate and process the data to produce the causative map of each selected factor, and R Studio is used to develop an SVM model to produce LHMs. The result showed that the mean annual rainfall and temperature is expected to increase in the future (2070-2099) under both RCP conditions. The LHMs are compared and shown by areas (km2) for present and future conditions under climate change scenarios RCP4.5 and RCP 8.5. The result from LHMs showed an increment of area class as moderate, high, and very high hazardous under the effect of climate change within the range of 0.3% to 1.1%. The LHMs produced are validated using the Area under the curve (AUC) and yield a value between 77.25% to 79.09%, indicating the acceptable performance of the model development.
