查询词典 bedrock

Coal-bearing seams in Shenyu mine area inclines northwest, the bedrock thickness on the coal seams increases northwest, and there are generally red soil water-resisting layer on the bedrock. To study on the coal-water friendly geological conditions for the water-resisting layer during the coal mining process, and to determine mining zones without causing obvious water table decline are an important approach to the water-conserving mining in the fragile ecological mine area of North Shaanxi.

榆神矿区含煤地层整体向北西倾斜，煤层上覆基岩厚度向北西方向增大，基岩之上普遍分布有红土隔水层，深入研究煤炭开采过程中不对含水层造成破坏的煤水共生地质条件，确定既可采煤、又可实现水位不明显下降的区域，是陕北生态脆弱矿区保水开采的重要途径。

For colluvial slopes, the usage of bedrock model or the assumption of a fictitious weak layer at the interface between colluviums and bedrock is a reasonable way for stability analysis to reflect common noncircular slides in colluvial slopes.

对於崩积层边坡的分析可采岩盘模式分析，或在崩积层与岩盘的界面引入一虚拟软弱层的方式，以得到合的分析结果。

Therefore, in the process of load transfer within the unconsolidated confined aquifer, the key strata of overburden rock are prone to have a compound breakage when the load on the upper interface of bedrock is great and the bedrock is very thin.

在松散承压含水层的载荷传递作用下，作用在基岩顶界面的载荷较大，当基岩厚度较薄时，采场覆岩关键层易产生复合破断。

With the increasing of the bedrock thickness, pressurized pace was increased gradually, the roof caving and surface subsidence were gentled step by step. When the thickness of roof bedrock was larger than 60m, the bench subsidence was not occurred, and the value of surface subsidence was also small. The mining technology was proper and highly active, and the support programme was feasible. The roof was controlled effectively by the support system, and achieved safety mining.

随着基岩厚度的增加，顶板来压步距逐步增加，顶板垮落与地表下沉越来越缓和，基岩厚度大于60m时，顶板来压不再出现台阶下沉，地面下沉量较小；针对不同厚度基岩提出的采煤方法合理，高效，支护方案可行，能够有效控制顶板，实现安全生产。

The paper discussed the main technical points of bedrock drilling, the design and selection of back reamers for different formations and drilling diameters, detailed construction technology of bedrock with typical engineering cases in China and prospected the future development.

论述了非开挖基岩钻进的技术要点及在不同地层、不同管径施工条件下对非开挖回扩钻头的设计及选用。结合国内几个典型的施工实例，详细阐述了非开挖基岩钻进的施工工艺。展望了该技术的发展前景。

In some places, hill-slope debris forms amantle over the bedrock and alluvium fills some of the valleys.

在部分地方，山坡岩屑在基岩上形成覆盖层，而冲积土则分布于部分河谷中。

Lean protein is a bedrock nutrient in the physical renovation process because it causes the basal metabolic rate to elevate; the metabolic thermostat, the rate at which our body consumes calories, increases when digesting protein.

瘦蛋白是一种营养物质的基石，因为它导致了装修过程中基础代谢率抬高；恒温的新陈代谢，人体消耗热量的速度增加时消化蛋白质。

Sediment from river is not the main source of the Rushan Bay now any more ,which leads to the change of balance of sedimentation power. Sediment will transport because of the drive of hydrodynamic elements in macroscopic view .Direction of suspended load is basicly the same as tidal current .Flood tide makes suspended load transport to tip of the inner Bay and to the Mouth in exterior Bay .The direction of longside sediment transport in two sides of the Mouth mainly focus in the Mouth .Because the coastline along the exterior Bay is very meandering and it belongs to the type of bedrock ,besides some sediment going into the inner Bay ,so actual net sediment discharge rate is less than calculation .It develops an ebb delta out of the Mouth and forms tidal sand ridge ,tidal washing canal ,barrier bar and marine physiognomy ;The result of model simulation disclosures that differences of sediment erosion and siltation between single tidal action and wave-current action are very big .From the analysis of sediment composition、sediment sources and stability of beach and ridge ,this article gets the conclusion that the channel has the possibility to silt ,though the course maybe very slow.

通过分析研究文章得出如下结论：沉积物平面分布与水动力的时空变化存在很好的相关性；口门外发育落潮流三角洲，形成潮流沙脊、潮流冲刷槽、浅滩、拦门沙等水下动力地貌；乳山湾河流来沙已不是湾内泥沙主要来源导致沉积水动力平衡发生改变，宏观上表现在泥沙受水动力驱动发生不断运移；悬沙运移方向与涨潮流方向基本一致，湾内涨潮流带来的悬移质泥沙向湾顶运移，湾外悬移质泥沙主要向口门方向运移；湾口两侧岸段沿岸输沙方向均指向口门方向，由于乳山湾外海岸线曲折，两侧岸段以基岩为主，加之部分泥沙进入湾内，实际净输沙量小于计算值；数值模拟发现潮流单独作用与波流共同作用下泥沙蚀淤模拟差别较大；从沉积物组成、泥沙来源及滩槽稳定性三个方面分析，文章认为研究区存在航道淤积的可能性，但过程相对较慢。
