Pisha sandstone is a special kind of soft rock in the semiarid region along up and middle reaches Yellow River Loess Plateau severely eroded by wind, rainfall gravity force. called "the most severe water loss soil erosion world" referred to as "Earth Cancer" local residents experts both at home abroad. The plan for control started 1950s. Since then series projects have been implemented, engineering vegetation measures developed widely used protect from erosion. seabuckthorn was introduced...
Rocky desertification is a form of land degradation occurring in tropical and subtropical regions, characterized by the destruction vegetation soil erosion caused natural or anthropogenic factors, resulting extensive areas exposed bedrock. Field tests were conducted three townships—Bolin, Longlai, Longlei—within Fengshan County, Guangxi Zhuang Autonomous Region, China, to evaluate effects various fertilizers (compound fertilizers, slow-release bio-organic fertilizers) on fertility, enzyme...
The Pisha sandstone area in the Yellow River Basin is one of regions with most severe soil erosion China and globally, its particularly challenging to control. W-OH, a hydrophilic polyurethane material, possesses controllable degradation properties. It can react water achieve stabilization resistance during curing process. material has been successfully utilized control areas. This study aims investigate impact W-OH on water/fertilizer retention plant growth through experiments hardness,...
The size and spacing of carrier media play a key role in EPS microbial community, hence the process performance biological wastewater treatment.
A heavy rainy season can result in many disasters, such as a dam collapsing and the water level of river rising. cross-river tunnel, an underground structure, will also be affected by rain. The discrete element method (DEM), main mechanical approach, has unique advantages that allow it to determine large deformation stress distribution particles. Referring studies, most which use finite method, tunnel model is proposed based on DEM this article. Different situ strata high pressures due...
Abstract In this work, a novel hydrophilic reactive polyurethane (HRPU) material and HRPU-based composite materials were prepared used as chemical anti-water erodibility for Pisha sandstone. The compressive strength, surface hardness, penetrability water contact angle investigated. results showed that the deformation rate of sandstone sprayed with HRPU/ethylene-vinyl acetate (EVA) was approximately 15%, significantly larger than other samples, while strength improved, providing good to form...
The effects of the wet-dry cycles on chemical compositions, microstructure, and mechanical properties Pisha sandstone were experimentally investigated in current study. A series uniaxial compression tests conducted to validate deterioration property specimens after cycles. In addition, evolutions mineral compositions microstructure characteristics confirmed by X-ray diffraction (XRD) scanning electron microscope (SEM). Experimental results indicated that with increase cycles, gradually...
Hammering tests are employed for detecting surface and internal damage; however, their accuracy depends on the experience expertise of inspectors. Because automation techniques can address limitations manual hammering tests, researchers have developed automatic inspection systems to replace or assist conventional inspection. Although several studies been reported, challenges hinder practical application results. The relative frequency identification algorithms complex diverse damage critical...
<p>The vegetation and stability of Pisha sandstone slopes are insufficient due to its inherent properties, such as low erosion resistance, strength, water stability, high porosity. In this paper, a new flexible slope protection method, which considers the combination hydraulic polyurethane(W-OH) planting mate technology, is proposed realize ecological restoration prevent soil steep slopes. The properties consolidated body W-OH were investigated. Furthermore, optimal proportion...
<p>Due to the hard surface and lack of necessary soil environment for vegetation growth, rock slope protection ecological restoration is one research focuses nowadays. In this paper, we proposed a flexible method based on membrane protect slopes including river road slope. The kind organic bags which perfused by mechanical equipment with plant seeds, soil, sand, vermiculite, rice husk, adhesive material, water retaining agent in certain proportion, forming suitable growth. Then...
