关键词:effective stress, low‐permeability reservoirs, natural gas hydrate production, numerical simulation,settlement, slope angle, the South China Sea

摘要:AbstractIt is important to study the effect of hydrate production on the physical and mechanical properties of low-permeability clayey–silty reservoirs for the large-scale exploitation of hydrate reservoirs in the South China Sea. In this study, a multiphysical-field coupling model, combined with actual exploration drilling data and the mechanical experimental data of hydrate cores in the labo...

关键词:damage evolution model of surrounding rock, discrete element method, force chains, gascharging–discharging cycle, gas storage in abandoned mine

摘要:AbstractGas storage in abandoned mines is one way to reuse waste space resources. The surrounding rock of gas storage reservoirs in underground roadways undergoes damage and deformation under the cyclic loading of gas charging and discharging, which can pose a risk to the safety of the reservoirs. This study establishes a true triaxial numerical model of rock mass with the discrete element meth...

Small-scale fire tests in the underwater tunnel section model with new sidewall smoke extraction

Shunyu Yue, Ruifeng Miao, Huihang Cheng, Maohua Zhong, Xiujun Yang

发布时间:2024-05-29

关键词:sidewall smoke extraction system, small‐scale fire tests, smoke control

摘要:AbstractThe Shenzhen–Zhongshan Bridge is a 24-km-long bridge and tunnel system, including a 6.8-km-long super cross section subsea tunnel. To solve the smoke exhaust problem of a super large cross-section subsea tunnel, the tunnel has a new smoke exhaust system that combines a horizontal smoke exhaust cross section at the top and sidewall smoke exhaust holes. In order to evaluate the potential...
