Article
Full-text available
The Chada rock avalanche is a prehistoric high-elevation giant rock landslide located in the Boshula Mountains, Lhorong County, Southeast Tibet. It is composed of conglomerates with a volume of 6.62 × 106 m3 and has a height difference of 1450 m and a transport distance of 3155 m. The accumulational landform shows characteristics indicating rock av...
Article
Flow-like landslide is one of the most catastrophic types of natural hazards due to its high velocity and long travel distance. In 2019, a large catastrophic landslide was triggered by heavy rainfall and occurred in Shuicheng County, Guizhou, China. The Shuicheng landslide was characterized by a short slip time, high speed, and long sliding distanc...
Article
A variety of joints of various shapes are widely developed in rock masses. An accurate account of the behavior of a joint rock mass requires a realistic model for the tribological behavior of joints, which requires further study to understand the influence of secondary asperities on shear strength and the shear failure mechanism of joints. In view...
Article
Identifying deep-seated toppling failure presents unique challenges for the study of natural slope deformation in mountainous regions. In the absence of an effective quantitative approach, this study aims to provide a comprehensive grading system in order to establish a slope engineering geological model that can evaluate the deformation of a deep-...
Article
The upper Minjiang catchment is frequently affected by a significant number of large to giant landslides. In one such massive older landslide, approximately 2 million m³ of sediment was reactivated, threatening the safety of a pylon on the landslide and the safety of the only route that allows high-speed travel from Wenchuan to Maoxian. To trace th...

On July 23, 2019, a large catastrophic landslide was triggered by heavy rainfall at Jichang Town, Shuicheng County, Guizhou, China. This high-speed landslide was characterized by a short slip time, long slide distance, and great destructiveness. In less than 2 min, about 2 million m3 of cataclastic basalt soil failed with a runout of about 1.25 km...
Article
Recently, various toppling slopes have emerged with the development of hydropower projects in the western mountainous regions of China. The slope on the right bank of the Laxiwa Hydropower Station, located on the mainstream of the Yellow River in the Qinghai Province of Northwest China, is a typical hard rock slope. Further, its deformation charact...
Article
Full-text available
The deformation failure mode of fractured rock slope is actually determined by the potential paths controlled by the structural characteristics of rock mass. In the complex fractured rock slopes,the intersections of structural planes with different types,sizes and dip angles make the damage paths more uncertain. The method of synthetic rock mass(SR...
Article
Full-text available
Rock mass unloading is an important rock engineering problem because unloading may impact the stability of a rock mass slope. Based on hydroelectric engineering principles, this study focuses on the classification of unloading zones to reflect the rock mass structure characteristics. Geological background and slope structure of the study region wer...
Article
Full-text available
Engineering mechanical properties of rock mass are largely influenced by the characteristics of weak joints. Concentrated parallel joints are well developed in a large hy-dropower station in southwest China, and the deformation behavior of these joint belts is a key factor affecting slope stability. Therefore, this paper performed a simulation by p...
Article
Full-text available
Rock mass is an important engineering material. In hydropower engineering, rock mass of bank slope controlled the stability of an arch dam. However, mechanical characteristics of the rock mass are not only affected by lithology, but also joints. On the basis of field geological survey, this paper built rock mass material containing parallel concent...
Article
Full-text available
Earthquakes that occur in a mountainous region can trigger a mass of landslides (ETL), and these hazards can cause relatively heavy casualties. Compared with other evaluation models and methods, quantification theory I is a multivariate statistical approach that can simultaneously process qualitative and quantitative variables. On the basis of the...
Conference Paper
Full-text available
Characterized by high seismic intensity and high geological disaster risk, the geological condition of Longmenshan is complex and unique. How to carry out route alignment in such complicated geological background and avoid geohazards is one of key issues. Based on the geological background, including landform, lithology, Geological tectonic, geohaz...
