When tunnel boring machines (TBMs) excavate through jointed rock masses, the cutting efficiency is strongly affected by shear strength of joints, mechanism which, however, remains poorly understood. In this study, a series disc-cutter indentation tests were conducted on granite mass specimens with different joint strengths. During indentation, cracking process was recorded digital image correlation (DIC) system. The deformation and specimens, behavior, breakage mode quantitatively...
The crack propagation evolution of carbonaceous mudstone under the action dry-wet cycles is an important cause unstable failure this type slope. This paper attempts to reveal mechanism mesocrack and macrocrack in from chemical, physical, mechanical perspectives. Firstly, soaking solution during was extracted for ion concentration test analyze chemical reactions mudstone. Then, CT scans were performed on samples study changing pattern mesostructure cycles. In end, properties characteristics...
Vacuum–surcharge preloading is widely used in soft soil foundation reinforcement projects. To study the characteristics of changes pore water pressure and settlement as a result effect vacuum–surcharge preloading, this paper, consolidation model was established for large–sized sand–drain fluid–solid coupling along depth direction while taking sequence actual surcharge vacuum into consideration by using FLAC3D, foundation’s process calculated analyzed detail. The results showed following: (1)...
Steep fill–bedrock interfaces usually appear in many filling soil infrastructures, such as airports, houses, and road embankments mountainous areas, when the excavation of rock slopes is constrained. These are prone to be tensioned up failure, which easily triggers landslides fill slopes. The anchor system buried soil, named radial cable system, was proposed for effectively enhancing stability steep interfaces. At interface, steel ropes section were equally divided into three subcables with...
Water inrush and mud outburst are one of the crucial engineering disasters commonly encountered during construction many railways tunnels in karst areas. In this paper, based on fluid dynamics theory discrete element method, we established a fractured rock mass inflow model using particle flow PFC3D numerical software, simulated whole process inflow, discussed effect size velocity change pressure gradient. The simulation results show that movement particles at corner wall when water is first...
There are few calculation methods for the design and construction of vacuum preloading to strengthen soft foundations. Based on FLAC3D, a model was established project Beijing–Shanghai high-speed railway. Through comparison measured values, following results were obtained: (1) The top surface reinforcement area sand drain can be regarded as load boundary, which realized by assigning node pore water pressure. (2) After 30 days action, settlement rate at each depth decreased significantly...
The objective of this study is to investigate the compressive strength and microstructural evolution recycled aggregate concrete (RAC) containing coarse fine clay brick aggregates. tests, scanning electron microscopy (SEM) observations, X-ray diffraction (XRD) tests were performed on RAC natural (NAC) different crushed contents. results showed that NAC decreased with increase content, growth rate their slowed down age. At same age replacement rate, bricks had less effect than coarsely...
In this study, an investigation on the formation mechanisms, deformation characteristics, and stability of Outang landslide, composed by three independent blocks (O1, O2, O3), is performed integrating site surveys, multi-technique monitoring data, numerical simulation. The results show that mechanism for O1 O3 slide-bulking, planar slide block O2. These along incompetent layers (ILs): IL1 slip surface IL3 O3. Furthermore, west local fast movement zone might evolve into deep failure. slope...
Quantifying the ecological carrying capacity has emerged as a crucial factor for maintaining ecosystem stability sustainable development in vulnerable eco-regions. Here, we propose new framework quantification suitable We applied this to calculate of Inner Mongolia from 1987–2015 and used geographical detector identify driving factors behind spatial heterogeneity. Our results revealed following. (1) The above-ground net primary production (ANPP) required support service soil conservation...
