A New Classification Method of Surrounding Rock Quality for Phyllite Tunnels Under the Condition of Layer Orientation Parallel to the Orientation of Tunnel Axis

Energy Science &Engineering, Volume 14, Issue 1, Page 47-60, January 2026.
Modified Mass Classification of Layered Rock Masses Based on the HC Method. ABSTRACT The HC method for hydropower is a commonly used rock mass quality classification technique in China's hydropower industry. Due to the anisotropic nature of the layered schist in the study area, and the varying angles between different tunnel layers and the tunnel axis,

Settlement Calculation of Pile Foundation With Different Shaft Resistance Models by Mean Vertical Additional Stress Coefficient Method

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study develops the mean vertical additional stress coefficient on the basis of vertical additional stress, and an analytical solution for calculating the settlement of pile foundations is derived accordingly. The method simplifies settlement calculations by simply layering the soil layers with different compression moduli, eliminating the need for

Structural Behavior of Reinforced Concrete Deep Beams: Comparative Analysis of Experimental and Finite Element Methods

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Reinforced concrete (RC) deep beams are increasingly used in structural applications such as offshore platforms, high‐rise buildings, foundations, and nuclear facilities. However, the absence of a universally accepted strut‐and‐tie method (STM) for their design remains a critical challenge.

Research on Failure Characteristics of Interlayer Water‐Resisting Rock Strata and Water Inrush Evaluation in Roof Goafs Under Deep and Shallow Repeated Mining

Geofluids, Volume 2026, Issue 1, 2026.
To address the risk of water inrush from old water‐logged goafs during deep and shallow repeated mining, this study investigates the failure characteristics of interlayer water‐resisting rock strata and establishes a corresponding water inrush evaluation method.

Spatial Decay Estimates for Elastic Plate System With Type II Heat Conduction

Journal of Mathematics, Volume 2026, Issue 1, 2026.
The classical Saint‐Venant principle has been extensively studied for harmonic and biharmonic models but remains largely unexplored for thermomechanical plates governed by hyperbolic (Type II) heat conduction, a conservative thermal model with unique dynamical features. This paper investigates the spatial decay properties of solutions to such a coupled

Robust Physics‐Informed Neural Network Approach for Estimating Heterogeneous Elastic Properties from Noisy Displacement Data

Advanced Science, Volume 12, Issue 48, December 29, 2025.
Heterogeneous distributions of elasticity parameters are learned from noisy displacement data using the Inverse Elasticity Physics‐Informed Neural Network (IE‐PINN). This approach integrates both data‐driven and physics‐driven methods to address the significant limitations faced by existing techniques.

A Comparative Study of Physics‐Informed and Data‐Driven Neural Networks for Compound Flood Simulation at River‐Ocean Interfaces: A Case Study of Hurricane Irene

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Simulating compound flooding (CF) at the river‐ocean interface within large‐scale Earth System Models (ESMs) presents significant challenges due to complex interactions between river discharge, storm surge, and tides. This study assesses the comparative advantages of physics‐informed and data‐driven machine learning (ML) approaches for ...

On uniqueness of the second boundary value problem solutions for the third order composite type equation in unbounded domains

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
In the paper the second boundary value problem for the third order composite type equations is investigated. We established Saint-Venants type energy estimates for weak solutions of the problem on Sobolev classes. The obtained estimates are used to prove

Saint?Venant's Principle in Anisotropic Media [PDF]

Australian Journal of Physics, 1965
Saint-Venant's principle may be stated (Sternberg 1954): "An equilibrated system of external forces applied to an elastic body, all of the points of application lying within a given sphere, produces deformations of negligible magnitude at distances from the sphere which are sufficiently large compared to its radius."

Saint-Venant principle in geotechnics

Инженерно-строительный журнал, 2010
The problem of determining the stresses in the ground mass are important for calculating the strength, stability of soils, and also their deformation by external forces and its own weight.There are three basic mathematical methods of solving the elasticity theory problem: the direct method, inverse method, semi-inverse method of Saint-Venant.
