Landslide volume, as a principal factor in assessing the disaster-causing capacity of potential landslides, needs to be estimated accurately and quickly. At present, volume estimation landslides is still dominated by traditional field surveys, method using power-law correlations between landslide area estimate also imperfect. Scholars often ignored crucial index rock resistance weathering erosion (IRWE) bedrocks, leading uncertainty coefficients (γ), applicable range this further...
Abstract The basal stresses generated by rock avalanches, along with the resulting seismic signals, act as important indicators that provide insights into avalanche dynamics. Here, an experimental study on propagation behavior and dynamics of granular flows moving a 3D‐printed bumpy substrate was conducted stress signature responses were analyzed. results indicate agitating layer emerges in nearly steady state increasing particle size, characterized base‐normal velocity internal shear...
Abstract Rock avalanches are catastrophic events that can be triggered by various geological and climatic factors. Large‐scale rock have been observed near fault zones, indicating a potential relationship between creep motions the initiation of avalanches. This study proposes physical mechanism explains how leads to near‐fault through stress redistribution. The Muztag avalanche which occurred in Ata, Kashgar, China is revisited using field measurements numerical modelling. We consider model...
The 2008 Wenchuan earthquake triggered many rapid and long runout landslides, which directly caused great loss of property human lives were responsible for a large percentage total damages by the earthquake. It is very important purposes landslide disaster prevention mitigation to understand mechanism initiation motion can potentially be deadliest ground failures. In this paper, field investigations some highly damaging landslides are introduced first, followed data from ring shear tests...
As a new type of bridge foundation, rectangular closed diaphragm walls (RCDWs) provide an efficient solution to controlling the settlement high-speed railway bridges. However, scant research on prediction for RCDWs has hindered their application in practical engineering. This paper attempts establish simplified approach predicting RCDWs. First, analytical model RCDW is established accordance with load transfer approach. Then, curves and related coefficients skin friction foot resistance are...
Abstract Continuous seismic signals are proposed as a useful quantitative information source for the estimation of rockfall properties. However, few studies have examined characteristics signal fragmentation‐related rockfalls. In this study, series laboratory experiments designed with crushable analog blocks freefalling and impacting on thin horizontal plate under different initial conditions (e.g., block volume, strength fall height) were conducted. Strong correlations observed between...
Rectangular closed diaphragm walls (RCDWs) are often used as bridge foundations because of their advantageous properties such high stiffness and construction efficiency, low cost, minimal vibration noise. However, there is currently a poor understanding the seismic behavior RCDWs in liquefiable deposit, this has limited practical application same. This paper presents results three dynamic centrifuge tests that were conducted to investigate liquefaction mitigation capacities with one two...
Abstract The properties of rockfalls, such as the volume and geometry detached rock mass well number diameter fragments, greatly affect their propagated behavior, different strategies are required to mitigate rockfall hazards. Landquakes generated by rockfalls regarded good proxies for those properties. To explore free‐fall impact dynamics a series experiments on granular masses were designed conducted with characteristics landquakes versus initial variables being analyzed. results show that...
Lattice-shaped diaphragm wall (hereafter referring to LSDW) is a new type of bridge foundation, and the relevant investigation on its horizontal behaviors scant. This paper devoted numerical study comparison static seismic responses LSDW pile group under similar material quantity in soft soil. It can be found that bearing capacity considerably larger than group, deformation pattern basically appears an overall toppling while clearly shows local bending during loading process. The...
