摘要:Abstract(#br)Quantitative assessment for the efficiencies of check dams is necessary for the purpose of reducing the risk of potential debris flow disasters. In this paper, an improved finite difference model is adopted to assess the efficiency of the check dam in Dagou debris fl...

摘要:Abstract(#br)A scattering problem of a plane dilatational wave disturbed by a lined tunnel with an imperfect interface embedded in an infinite unsaturated poro-elastic solid is investigated. By means of the Helmholtz theory and the wave function expansion method, the correspondin...

摘要:Abstract(#br)Experimental water retention curve (WRC) obtained under constant volume (isochoric) conditions is crucial in the coupled hydro-mechanical formulation of unsaturated soils and for studying the role of void volume changes on the water retention behaviour of porous medi...

摘要:Abstract(#br)The exploration and production of unconventional reservoirs, such as tight-gas sand, gas and oil shales, and geothermal deposits, require hydraulic fracturing treatments to increase reservoir permeability and enhance its production. However, the presence of natural f...

摘要:Abstract(#br)Ensuring the stability of the tunnel face and the unsupported span is a critical issue in conventional tunnelling. An improved prism-wedge model is established to reasonably evaluate the safety factor of a tunnel face and an unsupported span in cohesive-frictional so...

摘要:Abstract(#br)Based on the deformation characteristics of rigid pile, a quasi-equal strain assumption was proposed to analyze the consolidation properties of a rigid pile composite foundation. By considering the parabolic distribution of the horizontal permeability of the surround...

摘要:Abstract(#br)This study proposes a subset simulation (SS)-based approach for efficient slope reliability analysis involving copula-based cross-correlated random fields of cohesion ( c ) and friction angle ( ϕ ) of soils. First, the copula theory for modeling the cross-correl...

摘要:Abstract(#br)In this paper, a double-beam model of a composite working system including an upper pavement structure under traffic loads, an embankment fill layer, a geosynthetic-reinforced mattress, and the lower soft soil over the roadbed is developed. In the model, the reinforc...

摘要:Abstract(#br)Fundamental numerical studies of seepage induced geotechnical instabilities and filtration processes depends on accurate prediction of the forces imparted on the soil grains by the permeating fluid. Hitherto coupled Discrete Element Method (DEM) simulations documente...

摘要:Abstract(#br)Thermal cracking widely exists in many geoengineering practices (e.g., geothermal exploitation, nuclear waste disposal and CO 2 sequestration), and highly affects the efficiency and safety of the engineering applications. Some of these projects are constructed in sha...
