A Nonlinear Prediction Model of Antislide Pile Top Displacement Based on MIC‐SVR for Jurassic Landslides

Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022
In this study, a nonlinear prediction model of antislide pile top displacement is proposed. Based on the quantitative analysis of the rock mass structure characteristics of the soft and hard interbedded sliding bed in the Jurassic strata, the post‐thrust force and geometric characteristics of the top of antislide pile displacement, and bending moment ...

Height Propagation Law and Controlling Strategies of Acid Fractures in Carbonate Gas Reservoirs With Bottom Water Layer Under Different Stress Profiles

Geofluids, Volume 2025, Issue 1, 2025.
Acid fracturing is currently employed to develop the carbonate gas reservoir in the second section of the Dengying Formation at the Anyue Gas Field, Sichuan Basin. However, improper acid‐fracturing operational parameters pose a risk of fracture communication with the bottom water layer, leading to increased water production and a significant decline in
