Abstract A pre-assembled substation has the basic functions of electric power automation, compact structure, and easy installation, on basis which this study optimizes internal space structure designs an intelligent architecture using control. Then, to ensure stable operation in outdoor spaces, photovoltaic generation is used as auxiliary source enhance compensation substation. This also results substation’s box address stability transport issues associated with Finally, simulation...
This paper describes recent advances in the effect of soil creep on time-dependent deformation deep braced excavation. The is generally investigated using observational method and plain-strain numerical simulation method. more applicable for excavations soft clays constructed top-down can be conveniently used parametric analysis, but it unable to capture spatial characteristics lateral wall deflections ground movements. additional movements that are generated due account as large 30% total...
The use of geosynthetic-encased stone columns has been proven to be an economical and effective method for soft soil foundation treatment. This is widely used in civil engineering projects at home abroad. When the are applied deep clays, they a floating state. load-bearing deformation mechanism changed. interaction between aggregates, geogrid, worth studying, especially bottom column. In this paper, discrete element simulate column with 280 mm encasement depth clays. characteristics...
Sand elements in the natural or manmade field have often undergone initial static shear stresses before suffering cyclic loading. To explore effect of stress, a series undrained triaxial tests were performed on dense and loose calcareous sand under different stresses. The test results are used to describe stress response with relative density. Cyclic mobility, flow deformation, residual deformation accumulation three main failure modes varying levels. resistance is greater than that sand,...
The emerging upward shield method (USM) for constructing vertical shafts has been used in various projects, including the Midosuji utility tunnel Japan. A scaled-down model testing system, featuring a geometric similarity ratio of 1:30, was developed specifically studying USM. This system incorporates sand inflow control, propulsion data acquisition, and water level control. It facilitates detailed observation recording parameters such as displacement surface soil layers, support force at...
The pre-stressed high-strength concrete (PHC) nodular pile is a type of PHC with variable cross-section the shaft, and it has normally been applied in ground treatment projects recent years. shaft consists nodules, which introduce differences for load transfer mechanism compared to conventional pipe pile. In this paper, influencing factors bearing capacity were investigated based on group field tests numerical simulations. following conclusions obtained analysis test simulation results:...
The bearing capacity of traditional prestressed high‐strength concrete (PHC) pipe pile is hampered by the poor mechanical properties surrounding soil in soft areas, and PHC nodular can improve behavior foundation soils. installation process will induce larger disturbance to compared pile, there little research on effect pile. In this paper, coupled Eulerian‐Lagrangian (CEL) finite element method was adopted simulate penetration piles soil. radial stress displacement induced resistance at...
Relative density is an important index affecting the mechanical behaviors of calcareous sands. The dense sands present softening strength, whereas loose exhibit hardening strength. Furthermore, relative determined based on maximum and minimum void ratios obtained by using dry test. In this study, a series tests were carried out various mixed graded to explore their material properties relationship between limit ratio, considering effects test methods, equipment, fine content. It shown that...
