Effects of Source and Distribution of Organic Matter on Methane in Offshore Sediments of Zhoushan Iinated by Marine input. The organic matter content of sediments showed a trend of increasing gradually from top to bottom, and the organic carbon content (SOC) of sediments in methane-bearing reservoirs was higher than that in non-gas pools. The methane-bearing gas reservoirs in the pore sediments m

Assessment of the Engineering Properties for Mud Through CPT and VST in Hengqin Coast,hat the soil sensitivity of mud varies from 3 to 12, and the undrained shear strength . increases with soil depth and expressed by a liner equation. Based on the shear strength obtained from VST, the cone factor . of CPT for mud is calibrated for strength interpretation in Hengqin area, which varies

Research on TBM Tunneling Parameters Prediction and Stratum Recognition Based on Ascending Section nd penetration prediction were 0.961 and 0.956. Then, based on the real-time prediction results of the Bi-LSTM model, a particle swarm optimization SVM surrounding rock grading model was established to predict the surrounding rock grade from the rising section data with a prediction accuracy of 93.2

Numerical Study of Wave Induced Seabed Response with Sand Ripples,o an evident redistribution of the effective stress, causing a local concentration of soil stress below the sand wave trough. Moreover, the results also reveal that compared to flat seabed, the pore pressure on seabed surface fluctuates intensely, corresponding to the profile of sand ripples. As the

Earthquake-Induced Shear Failure in 3D Fracture Systems with an Application for Long-Term Safety Ask, Sweden, we use a distinct element method-based commercial software (3DEC) to build a three-dimensional faulted and fractured rock mass model, in which a primary fault zone together with a secondary fracture network obeying a power-law length scaling are generated. An earthquake is simulated as a

,Using Grout Curtain to Cut-Off Regional Groundwater in Maoping Lead–Zinc Mine, SW China,sign and installed to cut-off regional groundwater from north and south of the mining area. A red clay slurry modified by cement and sodium silicate was used to install this two grout curtains. Using combined drilling methods to reduce the drilling hole amount and save construction investment. The t
