Traffic-induced cyclic stresses in the subsoil are three-dimensional, and it is important to acknowledge that major, intermediate, minor principal have obvious impacts on permanent strain of subsoil. Therefore, a series true triaxial tests were performed intact marine clay investigate evolution major (ε1p) under long-term loads this study, considering effects amplitudes deviator stress (qampl), coefficient intermediate (bcyc), slope path (η). The test results indicated ε1p exhibits an...
Dredged marine soils (DMS) have poor engineering properties, which limit their usage in construction projects. This research examines the application of reactive magnesia (rMgO) containing supplementary cementitious materials (SCMs) to stabilize DMS under ambient and carbon dioxide (CO2) curing conditions. Several proprietary experimental tests were conducted investigate stabilized DMS. Furthermore, carbonation-induced mineralogical, thermal, microstructural properties change samples...
China has over 1500 open-pit mines and 5000 dumps consisting of waste rock from the mining process. Due to dump instability in an mine its diverse foundations, landslides mudslides frequently occur. Heaped loose concentrated heavy rainfalls are two important factors affecting slope stability a dump. Using high Dump II within Nanfen Open-Pit Iron Mine with height 300 m as case study, this paper first proposes physical model similarity ratio according on-site engineering geological survey...
The propagation characteristics of shear waves in granular sediments are usually used to assess the dynamic response and liquefaction potential marine engineering foundations. However, mesoscopic processes by which excitation frequency influences wave attenuation remain unclear. In this study, based on a triaxial bender element (BE) test model, behavior uniform spherical particles was simulated discrete method (DEM). It revealed that BE excites point source manner within unit cell assembly...
Ground disturbance and deformation caused by a controlled gas release prior to engineering construction are commonly encountered geotechnical geoenvironmental problems in shallow geology areas. In this work, typical characteristics of gas-charged sand the Hangzhou Bay China analyzed. It is found that occurrence configuration feature enrichment zone reservoirs similar common unsaturated soil, but its pore pressure several times larger than atmospheric pressure. The effect suction history on...
MgO-based binders enhance soil stability and CO 2 sequestration. This study examines soft dredged marine soils treated with MgO, integrated biochar or slag, demonstrating significant improvements in properties environmental benefits.
To investigate the post-liquefaction shearing behaviour of saturated gravelly soil, laboratory tests were conducted using a static–dynamic multi-purpose triaxial apparatus. In addition, numerical simulations discrete element method (DEM) performed to preliminarily understand micro-mechanism soil in monotonic loading after liquefaction. The influences dry density, initial confining stress and degree liquefaction on discussed, evolution micro-parameters granular system was also analysed....
Nanfen open-pit iron mine is the largest single in Asia. Because of lag extension project, section has slowly spread shape “V,” and disasters such as landslides occur frequently. In this study, first, NPR anchor cable monitoring, which shows supernormal mechanical characteristics can realize monitoring early warning target for whole landslide process curve bedding rock “2016-1101 landslide” lower wall mine, was analyzed, revealing failure force evolution cable. Then, based on Fish language...
Instabilities of shallow gas-charged seabed are potential geological hazards in ocean engineering. In practice, the conventional field sampling techniques failed to obtain undisturbed gas-bearing sediments from for laboratory mechanical testing because sensitive gas exsolution and escape sediments. However, preparation representative remoulded specimens is a challenging issue, it rather difficult quantitatively control content uniform distribution bubbles within specimen. Given above...
The influence of saturation on the Poisson’s ratio v reservoir sediments has an engineering significance in field oil and nature gas exploration. Based a self-developed combined (BE-EE-RC) test system, under dehydration path, variation silty-fine sand Hangzhou Bay, China, was investigated. Results show that P- S-wave velocities vary non-monotonically with decreasing at different net stresses, reach maximum optimum Sr(opt); Biot’s theory respect to Vp Sr matches well measured e data.
