ABSTRACT In geo‐energy engineering projects, temperature is an essential environmental variable, and accurately predicting its effect on the thermomechanical properties of geomaterials remains a challenge. Similar to fine‐grained soils, variation also crucial factor that affects stress‐strain response critical state behavior coarse‐grained soils. this study, model established for soils using theories from fractional plasticity. The evolution line with increasing can be well characterized by...
Crushing of grains can greatly influence the strength, dilatancy, and stress-strain relationship rockfill materials. The critical state line (CSL) in void ratio versus mean effective stress plane was extended to breakage (BCSP). A void-ratio-pressure index that incorporated effect grain crushing proposed according BCSP. Rowe's stress-dilatancy equation modified by adding index, which also into formulations bounding plastic modulus. BCSP-based surface plasticity model describe state-dependent...
Abstract Sand‐fines mixtures are commonly used engineered materials, and their mechanical behavior is significantly affected by density, confining pressure, as well fines content. Although many laboratory tests have been performed on sand‐fines mixtures, few works conducted its constitutive law. To adequately describe the of sand with different content, a novel elastoplastic model was developed for incorporating an equivalent granular state parameter into Rowe's stress‐dilatancy equation,...
Single-grain crushing tests were carried out on limestone with nominal particle sizes of 2.5, 5, and 10 mm to investigate the effect size acidic erosion grain strength, characteristic stress, probability survival. The stress at failure was calculated when particles broken. data showed that in addition size, acidity soaking time played significant roles determining strength a particle. Weibull distribution theory applied calculate modulus surviving crushing. results revealed decreased...
Intermittent theta-burst stimulation (iTBS) is a high-efficiency transcranial magnetic (TMS) paradigm that has been applied to post-stroke aphasia (PSA). However, its efficacy mechanisms have not clarified. This study aimed explore the immediate effects of iTBS primary motor cortex (M1) affected hemisphere, on functional activities and connectivity brains PSA patients. A total 16 patients with after stroke received 800 pulses for 300 s. All underwent motor, language, cognitive assessments...
A series of single-particle crushing tests was carried out to investigate the size effect coarse-grained mudstone soil strength with three categories nominal particle size, 2·5, 5·0 and 10·0 mm, during various numbers freezing–thawing cycles. On basis test results, main mode a single grain correlation between given characteristic stress probability survival were determined. The results also indicated that decreases increasing an number Moreover, Weibull modulus calculated examine...
Background: The left primary motor area (M1) stimulation has recently been revealed to promote post-stroke aphasia (PSA) recovery, of which a plausible mechanism might be the semantic and/or mirror neuron system reorganization, but direct evidence is still scarce. aim this study was explore functional connectivity (FC) alterations induced by M1 intermittent theta burst (iTBS), new transcranial magnetic paradigm, in and systems PSA patients. Methods: Sixteen patients accepted iTBS underwent...
粗粒料广泛应用于水利大坝、公路铁路路基及机场高填方边坡等对强度及变形要求较高的基础设施中。粗粒料颗粒粒径及颗粒强度离散性较其他岩土颗粒材料大，且在外荷载作用下易发生破碎；微生物胶结作为一种新型的绿色胶结方式，可以改善粗粒料的力学特性，抑制颗粒破碎。文章首先介绍了粗粒料颗粒强度相关理论分析方法：包括Weibull分布理论、尺寸效应、分形维数、雪崩动力学理论等；随后总结了研究粗粒料颗粒强度及变形特性的室内试验方法与技术：包括单颗粒破碎试验、一维压缩试验、声发射监测系统及微生物胶结技术；最后从粗粒料类别、外部环境因素、颗粒粒径、微生物胶结情况等方面对粗粒料单颗粒破碎试验和一维压缩试验结果进行分析，阐明了相关因素对颗粒强度、Weibull模量、压缩性、破碎量、声发射能量及能量耗散等的影响规律。研究成果有助于加深对粗粒料强度及变形特性的认识，也可推动粗粒料在实际工程中的应用。

At same time, more geotechnical workers have paid attention to influence temperature on mechanical characteristics rock soil mass. Existing experimental research shown that thermodynamic behavior for cohesive such clay silt is relatively mature but less noncohesive soil, especially sand. Based hollow cylinder triaxial specimen, series...
The slotted disk spring has been widely used given its nonlinear characteristics. However, the number of studies on them is limited, and influences nonuniform thickness have not investigated theoretically experimentally. Additionally, hysteresis caused by friction neglected in most studies. By introducing symmetric condition dimensionless variation parameter, present study establishes a mathematical model for springs with linearly graded thickness. treating segment as cantilever beams both...
浅层地热能是地热资源的一部分, 也是在当今技术经济条件下, 具备开发利用价值的地球内部的热能资源, 且在我国分布广、储量大, 再生迅速, 利用价值高. 利用地源热泵技术, 可将浅层地热能中的“冷源”或“热源”引入结构物中, 从而调节结构物的温度, 达到冬暖夏凉的效果, 减少碳排放. 已有研究表明, 目前我国浅层地热能开发现状是单级浅层地热能开发利用不充分, 浅层地热能的多级利用及其与太阳能等其他清洁能源融合开发严重滞后. 该种现状主要是目前我国对结构物、土体、结构物与土体接触面之间的热力学性质认识不全所致. 本文总结了近年来国内外土体热力学性质的试验研究进展, 着重对温控试验的加热机理、不同类型的温控试验过程、温控试验的影响因素等方面的研究进行系统介绍, 并对后续土体热力学性质的试验研究趋势进行展望.
