Landslides are catastrophic geological events that can cause significant damage to properties and result in the loss of human lives. Deep learning technology applied optical remote sensing images enable effective landslide-prone area detection. However, conventional landslide detection (LD) models often employ complex structural designs ensure accuracy. The complexity hampers speed, rendering these inadequate for swift emergency monitoring landslides. To address problems, we propose a new...
Large-scale landslides in sensitive clays cannot be explained properly using the traditional limit equilibrium or Lagrangian-based finite-element (FE) methods. In present study, dynamic FE analysis of clay slope failures triggered by an earthquake is performed a large-deformation modelling technique. A model for post-peak degradation undrained shear strength as function accumulated plastic strain (strain-softening) implemented analysis. The progressive development “shear bands” (the zone...
Groundwater seepage and an increased lateral earth pressure coefficient at rest (K0) increase the potential for triggering large-scale landslides in sensitive clays. After failure is triggered, successive retrogressive of soil blocks undrained condition influenced highly by K0. This paper presents numerical techniques modeling K0 using Eulerian-based large deformation finite-element method. The simulation was performed first a drained to calculate situ effective stresses forces, which then...
Flowslide and spread are two common types of landslides in sensitive clays. Empirical criteria, based on single or multiple soil properties slope geometry, have been proposed for a rough assessment potential landslide type retrogression distance. A large variation has found the comparison distance between empirical equations field data. In present study, flowslides spreads simulated using Eulerian-based large-deformation finite-element (FE) method. addition to strain-softening,...
Abstract China–Nepal Highway is an important international passage connecting China and Nepal. Owing to its location in a complex mountainous area the Qinghai– Tibet Plateau, Shigatse section of often impacted troubled by mudflow. In order effectively conduct road construction maintenance improve early disaster-warning capability, relationship between various hazard factors disaster points was analysed. It found that four such as slope, precipitation, soil type digital elevation have...
The karst landscape is widespread in the southern region of China. As a result underground mining activities, original stress equilibrium disrupted, causing redistribution overlying rock layer, inducing longitudinal fracture to expand and penetrate upwards, resulting rupture destabilization cave roof, thus triggering series engineering problems such as collapse, landslide, discontinuous deformation ground surface, soil erosion. In order study evolutionary characteristics buried fissures...
The geological structure of the Three-rivers basin is complex, with active tectonic movements and frequent earthquakes. topography in region differentially uplifted. Multiple earthquakes lead to landslide disasters. Wenchuan earthquake 2008 made mountain be taken seriously. Bedding rock accumulation landslides are common disasters, which threaten infrastructure construction basin. Taking “Xiaguiwa” as an example, we conducted field surveys shaking table model tests. PGA amplification...
Hydrological processes in mountainous watersheds, and how soil, bedrock, plants interact are still poorly understood. Through a dense network of soil moisture temperature sensors, high resolution electrical resistivity tomography monitoring, weather data we assess the above below-ground driving hydrological response hillslope during snowmelt summer monsoon. The monitoring transect covers different bedrock vegetation types, with steep upper part characterized by shallow covered pine trees,...
CuO films were prepared by ionic liquid assisted electrodeposition to be used as photocatalysts degrade organic dyes.
Purpose The major marine functional zoning plan (MMFZP) and (MFZ) are two important kinds of spatial planning (MSP) in China. Their developing implementation integral to rational utilization sustainable development. purpose this research is study how these MSP work coordination Design/methodology/approach This paper reviewed the present status China abroad presented a comparative MMFZP MFZ from different aspects, analyzing relationship between two. Findings found obvious differences MFZ,...
Human activities such as construction loading in upslope areas could be a potential triggering factor for many offshore landslides the 1979 Nice landslide. Post-slide investigations show that existence of marine sensitive clay layers might one causes large-scale submarine landslides. In this paper, finite element (FE) modeling technique is developed to analyze failure slope undrained condition. Nonlinear strain softening behaviour shear strength clays incorporated FE analysis. Strain...
