This study focuses on the Shantou Bay Undersea Tunnel and engages in theoretical research to develop a water inflow prediction formula associated with pore pressure, building upon Darcy's law. The has stronger adaptability. Moreover, Grey Relational Analysis is conducted based formulas considering various factors identify influencing circumferential ranking tunnel. Subsequently, stability analysis of undersea tunnel waterproof drainage systems carried out, three forms drainage:...
During the construction of a mountain tunnel, water inflow and rock instability are common occurrences due to unfavorable geological conditions, posing serious threats safety. This study focuses on proposed tunnel employs multiple formulas predict potential during excavation. Based amount deformation surrounding rocks, comprehensive determinations made for thickness grouting rings permeability coefficients. The results demonstrate that: 1) Different yield slightly varied outcomes but overall...
Distribution of joints and fissures under hydraulic coupling condition is particularly critical to the stability surrounding rock masses in underground engineering construction. In this paper, DDARF (Discontinuous Deformation Analysis for Rock Failure) RFPA (Rock Failure Process Analysis) are compared analyzed firstly based on laboratory tests. Then using preferred software RFPA, failure process, stress state, acoustic emission characteristics energy dissipation laws with different joint...
Granite structure has the characteristics of discrete distribution and random minerals, which is particularly critical to stability surrounding rock underground caverns, research process extremely complicated. In this paper, granite Dagangshan tunnel in sections class Ⅲ was taken as object, mineral composition proportion, macro micro analyzed by XRD analysis, SEM laboratory compressive test; tunnel’s section model with established using particle flow program PFC numerical simulation done,...
To solve the problem of water discharge in tunnel when passes through low-pressure water-rich fractured stratum, grouting plugging technology is studied. The scheme optimized field test. post-validation research numerically simulated and parameters complete sealing ring are analyzed. results show that: 1) Full can effectively improve funnel effect precipitation with good effect. With decrease permeability coefficient increase thickness ring, flow velocity around both decreased significantly,...
Based on the similarity theory, sandstone was taken as prototype, and rock‐like specimens were made with strength ratio of 1 : 1. Single “X” fracture double fractures prefabricated in specimen, crack propagation studied through compressive test. An improved discontinuous deformation analysis method (DDARF) adopted to simulate cracking process. Further, other factors should not be ignored such confining pressure temperature, which considered: rock’s propagations under loading unloading...
The characterization of rock fracture is essential for revealing and understanding the mechanism. In this research, sandstone characterized from perspective 3D morphology surface. quantified by two fractal dimension ( D ) calculation methods: cubic covering method(CCM) surface area method(SAM). applicability both methods verified special cases which one a 2D plane another novel model with 3. However, in actual application, shortcoming CCM rooted algorithm exposed, introduces distorted small...
