Based on non-equilibrium thermodynamics theory, this study establishes a fully coupled thermal-hydraulic-mechanical (THM) finite element model. This model innovatively introduces bound water temperature and particle temperature parameters to characterize microscopic thermal effects, systematically revealing the influence mechanism of temperature gradients on PVTD consolidation behavior. Through comparison with Abuel-Naga et al.'s (2006) experimental data on Bangkok clay, the model demonstrates g…

Energy piles, which serve dual functions of load-bearing and heat exchange, hold significant value in ground source heat pump applications. However, under stratified ground conditions, the heat transfer mechanism of pile-soil heat exchange is relatively complex. Most existing analytical methods are based on constant heat source models, and this simplified assumption cannot effectively reflect the impact of dynamic thermal power variations on the thermal response of energy piles. Therefore, impro…

The bound water in saturated clay, due to its unique electrical double-layer structure, plays a critical role in controlling the macroscopic thermo-mechanical behavior of clay. This paper focuses on the mechanism of temperature-dependent variation of bound water in saturated clay. By comparing research results from different scholars, it is found that slight differences in bound water density can lead to significant discrepancies in the calculated bound water content, thereby affecting the analy…

This study focuses on the application of ground source heat pump systems in subway stations, with particular emphasis on the thermal-mechanical coupling response and heat transfer mechanisms of energy slabs. Currently, the thermal performance and structural safety of such structures under actual operating conditions have not been sufficiently investigated. Based on the Dalian Metro Line 4 project, two sets of in-situ field tests were conducted: one employed a constant inlet water temperature mod…

Red beds primarily refer to continental clastic rocks formed during the Jurassic, Cretaceous, Paleogene, and Neogene periods, predominantly in lacustrine, fluvial-lacustrine transitional, or piedmont proluvial facies, which are exposed worldwide. For red bed slopes with interbedded sandstone and mudstone, the key disaster-inducing factor triggering landslides is the damage and deterioration of the mudstone layers. Due to the property of red bed mudstone to deteriorate upon water contact and disi…

The southwestern mountainous region features steep terrain, deeply incised valleys, and complex geological structures. Debris flows, as the primary type of geological hazard in this area, severely constrain regional economic development due to their typical characteristics of high-frequency occurrence, ultra-strong dynamic damage, and complex kinematic processes. Based on the OpenLISEM numerical simulation platform, this study integrates rainfall, topography, and material source parameters from …

To address the issues of low work efficiency, high safety risks, and blind spots in surveys during the investigation of high and steep unstable rock masses, this study takes the No. 1 high-position unstable rock mass of a hydropower project as an example. By utilizing close-range photogrammetry and ground-penetrating radar technologies, a survey system specifically designed for high and steep unstable rock masses was established. Technical means were employed to construct a three-dimensional obl…

Gas storage caverns are critical components of compressed air energy storage power plants. Lined rock cavern (LRC) gas storage has garnered widespread industry attention due to its flexible site selection and controllable scale. Accurately determining the internal pressure load borne by each structural layer of an LRC is a prerequisite for safety assessment and structural design analysis. Based on the elastoplastic theory of structural stress analysis, this study proposes a calculation method fo…

The Zhangjiazhai Reservoir dam site area in Guizhou Province is significantly affected by the coupled interaction of karst and igneous rock intrusion, resulting in the development of multiple deep weathering slots that pose severe challenges to engineering construction. Through surface geological surveys, trench exploration, drilling, geophysical prospecting, and geotechnical testing, three longitudinal dissolution-weathering deep slots were identified at the left abutment, and one horizontal we…

Landslide disasters are one of the major natural hazards in human history. Understanding the calculation method for the residual sliding force of landslides enables the targeted design of landslide control measures. In response to the relatively limited research and engineering practice concerning wedge-shaped landslides, this paper proposes a calculation method for the residual sliding force of wedge-shaped landslides and validates the rationality of this method through an engineering case stud…

In karst areas, the construction of dams and reservoirs is critically dependent on addressing leakage issues, which are pivotal to the success of such projects. The spatial complexity and dynamic evolution of karst development determine the intricacy of karst leakage problems. This paper analyzes the leakage characteristics of the Lanxi Reservoir. It begins by introducing the engineering geological and hydrogeological conditions of the study area. Through a comprehensive analysis of groundwater …

To investigate the effects of freeze-thaw cycles and soaking on the physicochemical properties, deformation characteristics, and state of dispersive clay, indoor physical and chemical tests as well as compression tests were conducted on dispersive clay. Based on the test results, a compression deformation formula for dispersive clay under freeze-thaw cycles and soaking conditions was proposed. The results indicate that after undergoing freeze-thaw cycles and soaking, sodium and potassium ions in…

[Abstract] In the current context of increasingly fierce global cultural competition, domestic cultural products face difficulties in "breaking through" and encounter challenges such as cultural dissonance and cultural discount when "going global" to attract fans. Against this backdrop, domestic cultural products represented by "Black Myth: Wukong" have broken through traditional narratives, successfully achieving "breakthrough," "global reach," and "excellence" through Chinese elements, exquisi…

Similarity is an important component of marital satisfaction for couples; however, current research on the relationship between the two presents conflicting conclusions. So, in which dimensions are couples actually similar, and how does similarity affect marital satisfaction? This study recruited 638 Chinese couples as participants and adopted the Couple-Centered Approach (CCA). Using Profile-Couple Similarity (PCS) and Actor-Dissimilarity Score (ADS) as indicators, the study integrated actor ef…
