Subsidence Induced(沉降引起的)研究综述
Subsidence Induced 沉降引起的 - In 2015–2016, combined with the subsidence induced by the Walker and Hadley cells, an atmospheric pattern similar to the Pacific–South American/South Pacific Convergence Zone seems to have contributed to intensification of downward motion over NEB, indicating an influence of Rossby wave train. [1] Across the eastern margin of the upper Yangtze Platform, the incompleteness (or absence) of S2 and S3 and lower Cambrian Terreneuvian strata along the platform margin and the extremely condensed Ediacaran–Cambrian transitional successions in the lower slope and basin may have been caused by differential uplift and subsidence induced by extensional faulting. [2] , 2021] the focus is on induced seismicity; here the focus is on subsidence induced by natural gas extraction. [3] The model is employed to study the subsidence induced by the dissolution of one or more gypsum lenses and the stability of the covering and the failure of a gypsum pillar in an abandoned quarry. [4] The proposed method is then used to compare with rectangular subsection method to predict the subsidence induced by multi-seam non-rectangular goafs within a coal mine in the Liu Fangzi area of China as a case study. [5] We discuss the subsidence induced by the dissolution of one or more gypsum lenses, the stability of the covering, and finally the failure of a gypsum pillar in an abandoned quarry. [6] Based on GPS surface subsidence monitoring and parameter inversion, the subsidence induced by two-seam mining is estimated and predicted. [7] A first preliminary analysis of the results made it possible the detection (or just the confirmation) of a number of deformation phenomena associated to different natural or anthropogenic causes: from secular creeping of seismic faults, to subsidence induced by fluid extraction, from slow landslides to inflation of volcanic areas. [8] The results of the study confirm typical patterns of subsidence induced by oil extraction. [9] Predictive analysis of the spatial and temporal evolution of the subsidence induced by hydrocarbon exploitation could be affected by a high uncertainty also related to the a priori identification of the most realistic deformation parameter values. [10] A prominent example is the subsidence induced by intensive groundwater exploitation. [11]2015-2016 年，结合 Walker 和 Hadley 细胞引起的沉降，类似于太平洋-南美/南太平洋辐合带的大气模式似乎促成了 NEB 向下运动的加剧，表明罗斯贝波的影响火车。 [1] 在上扬子台地东缘，台缘S2、S3和下寒武统地层的不完整（或缺失）以及下斜坡和盆地极度凝缩的埃迪卡拉纪-寒武纪过渡层序可能是由差异造成的。伸展断层引起的隆起和沉降。 [2] , 2021] 重点是诱发地震活动；这里的重点是天然气开采引起的沉降。 [3] 该模型用于研究一个或多个石膏透镜体溶解引起的沉降，以及废弃采石场中覆盖物的稳定性和石膏柱的破坏。 [4] 然后将所提出的方法与矩形分段法进行比较，以预测中国六坊子地区煤矿内多煤层非矩形采空区的沉降作为案例研究。 [5] 我们讨论了由一个或多个石膏透镜溶解引起的沉降、覆盖物的稳定性，以及最后一个废弃采石场的石膏柱失效。 [6] 基于GPS地表沉降监测和参数反演，对二煤层开采引起的沉降进行估计和预测。 [7] 对结果的第一次初步分析使得检测（或仅确认）与不同的自然或人为原因相关的许多变形现象成为可能：从地震断层的长期蠕变到流体提取引起的沉降，从缓慢的滑坡到火山地区的膨胀。 [8] 研究结果证实了石油开采引起的典型沉降模式。 [9] 油气开采引起的沉降的空间和时间演变的预测分析可能受到高度不确定性的影响，该高度不确定性也与最现实的变形参数值的先验识别有关。 [10] 一个突出的例子是密集开采地下水引起的沉降。 [11]
Surface Subsidence Induced 地表沉降诱发
To explore the mechanism of abnormal surface subsidence induced by fault instability, mechanical model for the fault slip and soil cantilever were separately established when mining in the hanging wall and footwall. [1] This paper provides guidance for the design of the CCGPB technique and the predictions of surface subsidence induced by the production process of underground mining. [2] Surface subsidence induced by mining subsidence affects the overlying buildings and nearby utilities. [3] Therefore, this technique provides a new approach for controlling the surface subsidence induced by coal mining. [4] Surface subsidence induced by underground coal mining activities, especially longwall mining operations, can cause various problems to interstate highways ranging from structural integrity, drivability to safety. [5] Surface subsidence induced by mining subsidence affects the overlaying buildings and nearby utilities. [6] Physical model tests are used to simulate surface subsidence induced by shallow salt cavity occurred at the interface between salt bed and overlying soil formation. [7] Surface subsidence induced by mineral extraction from underground mines can significantly affect the ecological environment and human life. [8] Surface subsidence induced by underground mining is one of the challenging problems in mining engineering, which can destroy ground surface buildings and cause huge economic losses to the mine. [9]为探讨断层失稳引起地表异常沉降的机理，分别建立了上盘和下盘开采时断层滑移和土壤悬臂梁的力学模型。 [1] 本文为CCGPB技术的设计和地下开采生产过程引起的地表沉降预测提供了指导。 [2] 采矿沉陷引起的地表沉降会影响上覆建筑物和附近的公用设施。 [3] 因此，该技术为控制采煤引起的地表沉降提供了新途径。 [4] 地下采煤活动，特别是长壁采矿作业引起的地表沉降会给州际公路带来各种问题，从结构完整性、可行驶性到安全性。 [5] 采矿沉陷引起的地表沉降会影响覆盖的建筑物和附近的公用设施。 [6] 物理模型试验用于模拟盐床与上覆土层界面处浅层盐洞引起的地表沉降。 [7] 从地下矿山开采矿物引起的地表沉降会对生态环境和人类生活产生重大影响。 [8] 地下开采引起的地表沉降是采矿工程中的难题之一，它会破坏地表建筑物，给矿山造成巨大的经济损失。 [9]
Land Subsidence Induced
We here investigate land subsidence induced by groundwater depletion and/or seasonal variations in Gotland, an agricultural island in the Baltic Sea experiencing recent hydrological droughts in the summer. [1] This study presents a workflow to quantify the terrestrial water storage change (∆TWS) and land subsidence induced by a reservoir's water impoundment using multiple satellite observations (GRACE, Landsat), land surface models (CABLE, GLDAS, NCEP, ECMWF), and GPS data. [2] We investigated the effects of land subsidence induced by underground mining on the soil quality in western China. [3]我们在这里调查由地下水枯竭和/或哥特兰岛的季节性变化引起的地面沉降，哥特兰岛是波罗的海的一个农业岛，在夏季经历了最近的水文干旱。 [1] 本研究提出了一个工作流程，使用多个卫星观测（GRACE、Landsat）、地表模型（CABLE、GLDAS、NCEP、ECMWF）和 GPS 来量化由水库蓄水引起的陆地蓄水量变化 (ΔTWS) 和地面沉降数据。 [2] 我们调查了地下采矿引起的地面沉降对中国西部土壤质量的影响。 [3]
