Abstract : The structural and morphological characterization of rock mass is of great significance to the excavation and construction of geotechnical and geological engineering. Digital panoramic borehole camera technology is an important means to obtain the structural morphology of rock mass quickly and effectively in the borehole. In view of the highlighted problems of the existing digital panoramic borehole camera system and its analysis software during the complex environment investigation, a method of Full article
Abstract : The water holding capacity of unsaturated soils is usually reflected by the changing laws of soil-water characteristic curves. The important influence of factors such as load and temperature on the soil-water characteristic curve has been gradually recognized, but studies on the combined effect of moisture-load-heat on the soil-water characteristic curve are rarely reported, and the analysis of its dominant influence factors is even rarer. In order to explore the water holding capacity of silty Full article
Abstract : The key to the evaluation of freeze-thaw performance of lightweight aggregate concrete after disaster lies in the accurate quantitative description and prediction of its freeze-thaw performance under the specific disaster degree. The initial stress damage of lightweight aggregate concrete was applied by repeated loading to simulate the disaster, and the relative dynamic elastic modulus was taken as the evaluation index to study the freezing-thawing performance of lightweight aggregate concrete w Full article
Abstract : Landslides often occur in steep mountain areas during heavy rainstorms. Establishing landslide prediction models is one of the essential strategies for disaster prevention in mountain areas. The kinematic subsurface-flow approximation and the infinite-slope instability analysis were used to develop a rainfall-induced shallow landslide prediction model. Firstly, the runoff hydrograph and the temporal variation of soil water storage were obtained by calculating the runoff yield and concentration o Full article
