Shaft Lining(轴衬)研究综述
Shaft Lining 轴衬 - Accuracy of hydrogeological and geotechnical investigation in place of shaft sinking is a key factor for selection of sinking method and design of the shaft lining. [1] The capacities of RC and SFRC for the shaft lining were calculated based on the Canadian concrete design codes CSA A23. [2] Under the interaction of various factors, study the flow field distribution in the flow channel, the downhole, and the annulus area of the shaft lining. [3] The designed system was implemented into shotcrete tunnel cross-sections as well as shaft linings and enables the determination of displacement profiles with high spatial resolution in the range of centimeters. [4] The unique feature of this research consists of developing an original optical fibre sensor and its application for distributed measurements of temperature in the shaft lining and surrounding rock mass. [5] Simultaneously, the main parameters, including surface subsidence velocity, cumulative surface subsidence(CSS), loose strata thickness(LST), the water level drop in aquifer (WLD), shaft wall thickness, construction methods and shaft wall types, and diameter ratio of shaft and shaft lining quality, are prepared to analyze the shaft stability. [6] To analyze this phenomenon, a computational fluid dynamics (CFD) model of heat and mass transfer processes in a mine shaft was developed, considering the vertical temperature gradient, roughness of the shaft walls, heat exchange with the shaft lining. [7] Based on these results, the reinforcement of the elements of the shaft lining (bored pile, cap beam, reinforced concrete ring beam) was selected. [8] To this effect, one of the simplest and most informative methods is arrangement of an observation station directly in the shaft lining to measure varying distances between check points. [9] The microgravity survey made inside the working mining shaft provided information on the density of rocks outside the shaft lining, regardless of the type of lining. [10] The earth pressure distributions along the shaft lining before and after the excavation were investigated. [11] This paper presents an experimental study on shaft lining concrete specimens under different confining and pore pressure difference. [12] To solve the leakage problem of shaft lining concrete drilled by the freezing method of extra-thick alluvium, hybrid fibers and microexpansion high-performance shaft lining concrete were prepared in this paper, and the related properties were studied experimentally. [13] As a solution to the problems mentioned above, the authors of this work present a very simple design of a shaft lining, called the tubing-aggregate lining, which utilises the leachability of salt rock massifs. [14] As an important factor, the in situ creep behavior of deep, frozen soil affects the mechanical properties of frozen walls and the safety and stability of shaft linings. [15] With the increase in shaft depth, the problem of cracks and leakage in single-layer concrete lining in porous water-rich stable rock strata has become increasingly clear, in which case the mechanism of fracturing in shaft lining remains unclear. [16]水文地质和岩土工程勘察代替钻孔的准确性是选择钻孔方法和轴衬设计的关键因素。 [1] 轴衬的 RC 和 SFRC 的承载能力是根据加拿大混凝土设计规范 CSA A23 计算的。 [2] 在各种因素的相互作用下，研究了流道、井下、轴衬环空区域的流场分布。 [3] 所设计的系统已应用于喷射混凝土隧道横截面以及轴衬，并能够以厘米范围内的高空间分辨率确定位移剖面。 [4] 这项研究的独特之处在于开发了一种原始的光纤传感器及其在轴衬和围岩体中的分布式温度测量的应用。 [5] 同时，主要参数包括地表沉降速度、累积地表沉降量（CSS）、松散地层厚度（LST）、含水层水位下降（WLD）、竖井壁厚、施工方法和竖井壁型、直径比等。轴和轴衬质量，准备分析轴的稳定性。 [6] 为了分析这种现象，开发了矿井中传热和传质过程的计算流体动力学 (CFD) 模型，该模型考虑了垂直温度梯度、井壁粗糙度、与井壁的热交换。 [7] 基于这些结果，选择了竖井衬砌构件（钻孔桩、盖梁、钢筋混凝土环梁）的配筋。 [8] 为此，最简单且信息量最大的方法之一是直接在轴衬中布置一个观测站，以测量检查点之间的不同距离。 [9] 在工作矿井内部进行的微重力调查提供了关于井筒衬砌外岩石密度的信息，无论衬砌类型如何。 [10] 研究了开挖前后沿轴衬的土压力分布。 [11] nan [12] nan [13] nan [14] nan [15] nan [16]
hybrid fiber reinforced
To solve this problem, hybrid fiber-reinforced concrete (HFRC) is proposed as a construction material for mine shaft lining. [1] This article proposes hybrid fiber-reinforced concrete (HFRC) mixed with polyvinyl alcohol fiber (PVA) and polypropylene steel fiber (FST) as a wall construction material to improve the bearing capacity and durability of frozen shaft lining structures in deep alluvium. [2] [1] developed a finite element model for the numerical simulation of a hybrid-fiber-reinforced concrete (HFRC) shaft lining structure. [3] To address the cracking and leaking of concrete in frozen shaft linings in deep and thick topsoil layers in coal mines, hybrid-fiber-reinforced concrete (HFRC) was developed. [4]为了解决这个问题，提出了混合纤维增强混凝土（HFRC）作为矿井衬砌的建筑材料。 [1] 本文提出混合纤维增强混凝土（HFRC）与聚乙烯醇纤维（PVA）和聚丙烯钢纤维（FST）混合作为墙体建筑材料，以提高深冲积层冻结轴衬结构的承载能力和耐久性。 [2] [1] 开发了一种有限元模型，用于对混合纤维增强混凝土 (HFRC) 轴衬结构进行数值模拟。 [3] nan [4]

In order to economically and reasonably solve the problem of mineshaft support in complex geological conditions, the mechanical properties of high-performance steel-fiber-reinforced concrete (HPSFRC) and its application in mineshaft lining structures were investigated in this study. [1]Concrete Shaft Lining
The field test study of the high-performance concrete shaft lining was carried out in-1120m ingate and-1114m to-1124m shaft in Sha-ling Gold Mine, and its stress and deformation were monitored and analyzed. [1] As coal resources must be mined from ever deeper seams, high-strength, high-performance concrete shaft linings are required to resist the load of the soil surrounding the deep freezing well. [2] This study explores the effects of vibration damage to young C65 concrete shaft linings caused by close-range blasting excavation using the finite element method. [3]在沙岭金矿1120m内门和-1114m至1124m竖井内进行了高性能混凝土衬砌的现场试验研究，对其应力和变形进行了监测和分析。 [1] nan [2] nan [3]

[1] The in-situ lateral temperature around freezing pipes in an artificially frozen shaft lining (FSL) is always nonuniform. [2] To address the cracking and leaking of concrete in frozen shaft linings in deep and thick topsoil layers in coal mines, hybrid-fiber-reinforced concrete (HFRC) was developed. [3]本文提出混合纤维增强混凝土（HFRC）与聚乙烯醇纤维（PVA）和聚丙烯钢纤维（FST）混合作为墙体建筑材料，以提高深冲积层冻结轴衬结构的承载能力和耐久性。 [1] nan [2] nan [3]
