The spatial information of rockhead is crucial for the design and construction tunneling or underground excavation. Although conventional site investigation methods (i.e. borehole drilling) could provide local engineering geological information, accurate prediction position with limited data still challenging due to its variation great uncertainties involved. With development computer science, machine learning (ML) has been proved be a promising way avoid subjective judgments by human beings...
Soil liquefaction is a major geo-hazard. As could occur anywhere in sand layer and result large-scale lateral spreading, treatment for needs to be carried out over large extent. The cost-effectiveness of the then becomes consideration. With development microbial geotechnologies, some new approaches mitigation have been developed. Some methods offer more advantages existing methods. This paper gives an overview recent progress bio related soil These include both bio-cementation biogas...
Microbial (or bio-) desaturation is a new method for mitigation of the liquefaction hazard sand. In this paper, series monotonic and cyclic triaxial tests was performed on bio-desaturated sand under undrained conditions to demonstrate that bio-desaturation effective in enhancing resistance either or loading conditions. The test results showed that, loading, shear strength increased by more than two times behaviour soil changed from strain softening hardening when degree saturation (S r )...
Hydrogen is regarded as an ideal zero-carbon fuel for internal combustion engine. However, the low mass flow rate of hydrogen injector and volume heat value strongly restrict enhancement engine performance. This experimental study compared effects single-injectors double-injectors on performance, pressure, release rate, coefficient variation (CoVIMEP) based a single-cylinder 0.5 L port injection The results indicated that number injectors significantly influences maximum brake power improved...
Underground cable is difficult to find and fix once damaged. At the moment of fault, wire core sheath are short. The current through contains massive fault information. steady-state component transient can be basis detection. Make simulation under different angle resistance using PSCAD software. shows that from others when fault. This paper a detection method by monitoring sheath. Using MATLAB analysis data, results show effectively detect main insulation breakdown. this realize online power
Despite its wide use as a tool in foundation design, the piezocone penetration test (CPTU) has been rarely recommended to work for design and analysis of laterally loaded piles. Obtaining lateral response pile foundations is complicated engineering problem, especially nonhomogeneous soils. This paper presents review relationship between bearing piles introduces framework estimating p-y curves clays directly using CPTU parameters. To validate this method, full-scale load tests bored with...
With the increasing consumption of traditional energy and rising environment pollution, as well gradually improving requirements users for power supply, application distributed generation based on renewable clean technology has been more wide in system. As an effective form access to distribution network, micro grid combines power, storage equipments loads through control management make up a flexible, controllable autonomous system, which can operate both grid-connected islanded states...
The need for underground development has been expanded due to rapid urbanization and reduce the negative impact on city living. In recent years, 3D geological modelling widely used by engineers geo-scientists desk study shown its capability of integrating geotechnical information better usage in building civil engineering projects. To provide techniques instruction(?), a Geo-data Modelling Management System (GeM2S) established understand subsurface conditions Singapore. However, stratum...
Bio-gelation is a new method for improving the hydraulic and mechanical properties of sandy soil through production polymeric gel to fill in pores soil. In this paper, study on engineering behaviour loose sand treated using presented. A series permeability undrained monotonic cyclic triaxial tests was carried out both clean bio-gelled sand. The test results showed that coefficient reduced by three four orders magnitude samples, higher alginate concentration, lower permeability. tests,...
Distributed generation (DG) has been largely used in distribution network recent years, which brings more security, reliability, and economy, but some bad effects to the network. In this study, recovering loads, less switching actions power loss are considered establish mathematical model of fault recovery with DG. The particle swarm optimisation algorithm is solve problem, strategy obtained. Besides, impact DG location on studied, simulation results show that when located dispersedly...
The stable operation of power transformers is important guarantee system stability. Nevertheless, accidents winding instability occurs intermittently, which exerts huge harm to the secure and even systems. Moreover, axial a major type failure. When natural frequency windings approaches electromagnetic forces, structures will resonate intensively, causing occur. Therefore, resonance should be avoided. This paper presents stability analysis simulation transformer understand mechanism. At...
The control strategies of micro grid is an important topic for grid. With the development DC grid, drawing more and attention. Nowadays, most widely used strategy droop control. All distributed generators energy storage systems share loads through different coefficients in This paper proposes a grids based on power flow realizes PSCAD. comparison between made to show improvements.
Investigations of thermo-hydro-mechanical (THM) processes in geomaterials have become a continuing concern due to the increasing interests application geothermal energy. In last two decades, number THM coupled constitutive models were proposed for soils and rocks based on either elastoplastic theory or thermodynamics. The practical inevitably requires computational approaches such as finite element difference methods. this paper, simple framework saturated is proposed. An effort made explain...
