In this paper, the Guangxi’s red mud disposal field is taken as the study area. Appropriate calculating parameters and boundary conditions were selected based on the survey data to build a Mohr-Coul0mb and fluid model under the plane-strain condition. FLAC software was adopted to simulate the distribution of pore water pressure, filtrate seepage paths, and leakage of the dam body under conditio...

Biopolymer soil treatment has been introduced as the latest technological innovation in stabilization and improvement. Biopolymers with agar, guar, xanthan, casein, gellan sodium alginate have commonly studied to improve strength, reduce hydraulic conductivity prevent erosion of highly permeable materials. Among those, xanthan gum is perform better terms lowering permeability. In this study, ef...


 In the process of metro station construction, partition wall is usually used to prevent displacement soil behind ensure construction platform. This research aims analyze response keep safety structure. The time-horizontal and cracks are measured during construction. finite element software FLAC 3D simulate wall, reasons cracking analyzed by simulation measurement data. stiffness self-sta...

Presented here is a granular soil model created to investigate the soil pressures which develop behind integral bridge abutments. The problem is introduced along with a brief summary of the fundamental behaviour, the model produced, and the initial validation. The paper looks at the initial outcome of the final validation procedure where experimental behaviour of an abutment is compared to the ...

The Tashan coal mine is selected as a case study to determine the deformation and damage mechanisms of lower roadway in close-range residual pillar area. Roof drilling peephole technology applied detect roof surrounding rock. A boundary invisibility equation derived for plastic zone circular hole based on theory butterfly non-uniform stress field which principal occurs at an arbitrary angle ver...

A cantilever roadheader is the main tunneling equipment for underground coal mine roadways. The key to safe, efficient and intelligent development of enterprises achieve autonomous cutting control roadheader. In order realize automatic shaping a large-section roadway, path planning method secondary were studied. Wangjialing 12307 belt roadway was used as engineering background, vertical displac...

Abstract Underground quarrying is rarely adopted for granite extraction due to the difficulties in implementation of traditional technologies ( drilling and explosive) . As alternative explosive , combination diamond wire water jet seems be most promising available technology. The cutting performance achievable with technology depends on operative parameters, material characteristics state stre...
