Penetration grouting technology is an important technical means to improve the mechanical properties of gravel soil layers, and time-varying characteristics Newtonian fluid viscosity have influence on morphology effect penetration grouting. However, these are not considered in current research mechanism In this paper, by studying basic rheological equation fluids its dynamic law, motion discussed, theoretical analysis experimental research. Based this, columnar diffusion (TVNCPGDM) derived,...
Debris flow, the most extensive and severe geological hazard along Karakoram Highway, frequently blocks Highway. Based on methods of field measurement, indoor statistical analysis theoretical research, this paper discusses relationship between four types debris flow The are rain type, glacier ice lake break type freeze–thaw their particle characteristics gully slope also considered in discussion. results as follows: (1) provenance size is controlled by flow. Generally, average equivalent...
In the context of climate change, enhanced human activities and ecological changes, danger level for mountain floods has increased significantly, posing direct or potential hazards to local residents. To determine current status, focus trends in flood research, this study, we visualize number publications citations, countries institutions engaged co-citations key literature, keyword categories research areas, using timeline analysis burst detection based on bibliometric software CiteSpace...
Abstract The long-term erosion of rock by solution can induce a series karst problems. Therefore, this study focused on limestone and conducted dynamic dissolution experiments under deionized water CO 2 conditions to the deterioration mechanism nonequilibrium conditions. results showed that degree degradation mechanical properties samples in was obviously greater. In environment, sample is mainly controlled physical softening action solution. process be divided into two stages. early stage...
The intricate morphology of porous media can considerably affect the progression penetration and diffusion grouting slurry. In this study, a Newtonian fluid’s refined seepage motion equation was proposed to incorporate impact tortuosity on process into gravel soil, column-hemispherical mechanism analyzed using method theoretical analysis. Utilizing secondary-development programming techniques, numerical simulation program developed with COMSOL Multiphysics model fluid in pattern, considering...
Abstract Uniaxial compression tests were conducted on four groups of coal samples under dry condition and 0, 3, 5 MPa water immersion pressure using acoustic emission, scanning electron microscopy, a digital scattered spot deformation monitoring system to investigate the mechanical properties damage characteristics action pressure. The results showed that as increased, water–rock interaction intensified aggravated internal samples. uniaxial compressive strength, elastic modulus, peak strain...
Composite foundations have been widely used and promoted in practical engineering applications. However, research on the joint-bearing mechanism of piles soil within composite is still not comprehensive enough. This paper proposes a method for calculating additional internal forces foundations. Based three-dimensional finite element analysis, this study investigates variation patterns stress, displacement, depth direction under action upper loads when using friction end-bearing piles. aims...
Although disintegrated dolomite, widely distributed across the globe, has conventionally been a focus of research in underground engineering, issue slope stability issues dolomite strata is gaining increasing prominence. This primarily due to their unique properties, including low strength and loose structure. Current methods for evaluating stability, such as basic quality (BQ) probability classification (SSPC), do not adequately account poor integrity structural fragmentation characteristic...
To study the influence of water–rock interactions on deterioration rock, particularly problems complex dissolution mechanism dolomite and difficulty in establishing chemical damage, obtained from a tunnel Yuxi City was utilized. The macroscopic microscopic characteristics were analyzed using an indoor test combined with hydrochemical area, which found to be favorable for dissolution. indicates decomposition crystals, crystal failure mode is divided into intergranular dissolved pores...
Abstract. Pile–slab retaining walls, as innovative rockfall protection structures, have been extensively utilized in the western mountainous regions of China. With their characteristics a small footprint, high interception height, and ease construction, these structures demonstrate promising potential for application worldwide, such Himalayas, Andes, Alps. However, dynamic response upon impact resistance energy remain ambiguous due to intricate composite nature structures. To elucidate this,...
Conducting research on slope failure risk assessment is beneficial for the sustainable development of slopes. There will be various modes considering both randomness groundwater level and soil shear strength parameters. Based integrated probability (IFP), traditional analysis needs to count all modes, including (Pf) coefficient (C), one-by-one. A new method that uses sum element calculate overall proposed in this paper considers The determined by their location information situation; area....

In order to solve the rock burst disaster during excavation of deep buried high stress hard tunnel, method changing properties surrounding by blasting is proposed in this paper. This can effectively change physical and mechanical rock, reduce storage capacity corresponding variable energy, transfer concentration position layer, which an effective means control burst. Taking tunnel with rockburst tendency as example, distribution characteristics displacement changes under different...
Pulse hydraulic fracturing (PHF) is a key technique for reservoir stimulation. PHF can well accelerate the rupture of rock. However, supercharging mechanism not fully understood. The main reason that pressure distribution and its variation, especially peak characteristics, are unclear inside pipe fissure. present research focuses on sine pulse applied at inlet or fracture to reveal variation regularity with frequency, amplitude, length, diameter wave speed. First, weakly compressible...
As an anisotropic porous media, coal’s intrinsic permeability is sensitive to stress variably in different directions. Likewise, the degree of damage sustained by internal solid skeletal structure under external stresses anisotropic. Four parameters are introduced: stress-based loss rate (PEL) and strain-based (PSL) highlight sensitivity deformation characteristics during loading process; irrecoverable coefficient (EIP) (SIP) describe irreversible features whole load cycle. Stress vertical...
