An improved vacuum preloading method was developed to consolidate clay-slurry fill that is hydraulically placed in seawater for land reclamation. This adopted both a and an air-pressurizing system. In the system, new connector connect each prefabricated vertical drain (PVD) directly horizontal pipe used lieu of sand blanket. compressed air injected into soil accelerate consolidation. Field pilot tests using existing systems were carried out at same site. The testing data showed better...
The ability to capture permeability of fractured porous media plays a significant role in several engineering applications, including reservoir, mining, petroleum and geotechnical engineering. In order solve fluid flow coupled flow-deformation problems encountered these both empirical theoretical models had been proposed the past few decades. Some them are simple but still work certain circumstances; others complex also need some modifications be applicable. Thus, understanding...
Abstract A systematic geometric algorithm is developed to generate particle packing with high density, controllable gradation, and uniform spatial distribution for discontinuous deformation analysis (DDA). The incorporates a lattice searching technique expedite overlap detection reduce computational costs during generation. Additionally, Fourier transformation method utilized analytically handle detections on arbitrary irregular boundaries. To evaluate the efficiency accuracy of proposed...
Abstract A detailed and fully coupled thermo-hydro-mechanical (THM) model for fractured rock is presented. This distinguishes itself by harmoniously integrating elastoplastic material behaviour with a continuum damage mechanics framework. Solid matrix displacement, pore fissure water pressures temperature of the solid are introduced as primary nodal variables. The ingenuity this research embedded in intricate coupling THM processes plastic deformation double porous medium, venture that...
The effects of karst caves on tunnel stability were numerically investigated using the distinct lattice spring model (DLSM). DLSM was validated by investigating mechanical behavior Brazilian discs with various sizes central circular holes. Then, cave U-shaped under positions (top, bottom, and right side tunnel), tunnel-cave distances (0.5–4 times radius arc), shapes (circular, rectangular flat, vertical caves). failure processes those conditions analyzed both process final patterns...
The dynamical responses of rock subjected to blasting and impact have been concern in most underground projects. Due the size effects strain-rate enhancement induced by inertial effects, dynamic structures show multi-scale characteristics. Thus, order achieve better understanding rocks, both computation accuracy numerical efficiency taken into account. This is achieved further development a continuum-discontinuous element method code, called GDEM, with new type bounding-surface damage model...
