The inversion of the ground stress field in rock masses is critical for accurate tunnel and underground engineering design. This study addresses challenge accurately capturing both primary secondary components masses. consists field, generated by applied tectonic loads, a which cannot be fully explained these loads attributed to long-term processes. unexplained often non-random nature. To improve accuracy inversion, we propose prioritizing use regression model with constant term. better...
The exposing of dental implant into the maxillary sinus combined with membrane perforation might increase risks failure and complications. Objective: purpose this study was to investigate effects penetration cavity in different depths on osseointegration health a dog model. Material Methods: Sixteen titanium implants were placed bilateral molar areas eight adult mongrel dogs, which randomly divided four groups according penetrating extents cavities (group A: 0 mm; group B: 1 C: 2 D: 3 mm)....
The gently tilt-layered shale displays anisotropic behavior and includes structural planes that cause the rock to exhibit weakened features. As a result, load-bearing capacity failure mechanisms of this type differ significantly from those other types. A series uniaxial compression tests were performed on samples Chaoyang Tunnel investigate damage evolution patterns typical characteristics shale. An acoustic emission testing system was incorporated analyze parameters during loading process....
The deformation characteristics and the timing for secondary lining support in high geo-stress soft rock tunnels have drawn significant attention. In carbonaceous shale formations, tunnel construction deformations are very pronounced under disturbances due to development of joints, dense fractures, poor interlayer bonding. With Xishuangbanna as our research backdrop, this study meticulously analyzed patterns inherent constructed within schist formations. Employing a comprehensive approach...
A series of model tests were performed to investigate the load-bearing mechanism a mined railway tunnel lining under water pressure. To characteristics different types linings, fully closed pressure exerting device for noncircular section was invented. large-scale test (1:30) combined and soil pressures conducted mechanical characteristics, deformation, stress distribution, crack development process, failure mode underwater mined-tunnel lining. The results indicated that high-speed Class IV...
Abstract Complex geological environment and difficulties in operation maintenance of mountain tunnels result a lot damage during the period tunnels. Therefore, risk assessment reinforcement technologies for complex need to be developed improved. As result, this paper, research on safety influence factors their weights was conducted based Fuzzy Comprehensive Evaluation (FCE) Analytic Hierarchy Process (AHP), fuzzy set influencing established, membership functions at index level were...
Influenced by the anisotropy and water-softening characteristics of gently inclined layered shale, many tunnels have encountered bottom deformation issues during construction operation, which severely impact safety tunnel structures. The energy evolution law rock damage can provide support for assessment prediction structure deformation. However, most studies been conducted on enstatite, granite, sandstone with limited research shale. In this study, both conventional single-cyclic...
