This paper proposed an improved stepwise algorithm to simulate the grout diffusion in a single fracture considering dynamic grouting parameter boundary condition and spatial- time-dependent viscosity of grout. The method was more effective could result variation key output parameters at any measurement point/time (in space time). Based on algorithm, three types pressure conditions, which are applicable engineering practice, were designed illustrate process. Compared with constant grouting,...
A large-scale water capsule was formed after 8 times inrush of mud and in Yonglian tunnel. The seriously inhabited the construction By combining with geological conditions tunnel site, causes characteristics were analyzed. Its spatial location size explorated by comprehensive exploration methods. In order to control capsule, treatment scheme composed full-face curtain grouting left decompression drainage right made, composite controlling methods proposed. technology applied treatment. It...
The flow of cement‐based slurry within concentric annular geometry is a major problem study in the field engineering, especially regarding prevention water ingress an annulus formed during shaft construction utilizing artificial freezing technique China. In this study, analytical governing equation motion for axial incompressible Newtonian fluid long derived under condition high groundwater pressure. A stepwise calculation method proposed to describe grouting process based on two injection...
High power density energy regeneration is one of the effective solutions to solve contradiction between improving damping performance and consumption active suspension. The hydraulic commutator used realize rectification variable speed/pump/motor with few teeth difference gear pairs match speed, combined permanent magnet motor generation supply put forward kilowatt level high mechanical-electrical-hydraulic regenerative suspension system for high-speed tracked vehicles. mathematical model...
The deep mining of coal mines in North China faces the serious threat water inrush from karst aquifers seam floors, and regional advance grouting technology (RAGT) is an effective means to prevent control such disasters. However, it difficult choose pressure during implementation RAGT, excessive will lead splitting fracture reduce effect. In this study, based on Bernoulli equation, relationship between ground critical established. Based Hoek–Brown (H-B) strength criterion a mechanics...
During the process of managed aquifer recharge (MAR), when aerobic surface water is recharged into reductive aquifer, redox environment changes along pathway. MAR practice can reshape initial groundwater bacterial community, and further induce variations in bacteria-mediated hydrochemical reactions. In this study, laboratory-scale column experiments were conducted to simulate processes aerobic/anaerobic aquifer. The results showed that concentration DO during was higher than anaerobic...
In this study, the phase-structure and rheological response-behavior of multi-walled carbon nanotube (MWCNTs) modified asphalt-binder (MWCNTs-MA) were measured quantified in laboratory. The changes molecular dynamics due to MWCNTs modification simulated based on intermolecular interaction energy computations, electrostatic potential surface analyses modeling matrix. properties such as viscosity complex modulus, both base asphalt-binders, determined using standard Brookfield viscometer (BV)...
In order to study the new high efficiency advanced detection technology of coal roadway, characteristics ideal advance are analyzed. Dual- frequency IP method is based on Induced polarization effect (rock). The range angle and length scanning achieved by simulation comply with character electric field superposition. So, dual can meet requirement roadway. research results provide theoretical support for development equipment.
