The fourth confined aquifer is the main compressive layers in recent years in Shanghai.It is corresponding to the current mode of groundwater changes. 与现阶段含水层的水位变化模式相联系，第四承压含水层是上海最近几年来地面沉降的主要沉降层。
Fourth confined aquifer 第Ⅳ承压水
Sometime the term artesian is used to denote a confined aquifer. 有时候人们也用自流含水层这一术语表示承压含水层。
A confined aquifer is also known as a pressure aquifer. 承压含水层又叫压力含水层。
The paper analyses groundwater regime in the confined aquifer of the area of Puxi in Shanghai. 摘要本文以上海市浦西地区为例，对其承压水的动态进行了综合分析。
The confined aquifer cut by the river thalweg keeps closely hydraulic relationship with the river. 二维模拟结果表明：被河泓切割的承压含水层动态与江水位关系密切；
Strip method was used as main mathod in caol minging above confined aquifer in recent years. 近年来,条带法被用来作为承压水上采煤的主要采煤方法。
Ground water is the water contained in interconnected pores located below the water table in an unconfined aquifer or located in a confined aquifer. 地下水是指赋存于地面以下岩石空隙中的水，狭义上指赋存于地下水面以下饱和含水层中的水。
This is the fundamental source for the supports crushing during coal mining under the unconsolidated confined aquifer in East China. 这是造成华东矿区部分矿井在部近松散承压含水层开采时工作面发生压架事故的根本原因。
It was found that the elastic storage of the seabed semipermeable layer can enhance the head fluctuation in the confined aquifer when the semipermeable layer is enough long. 研究结果表明，当海底弱透水层延伸足够长时，它的弹性储水对承压含水层中的海潮引起的水头波动有增强作用。
The overburden soil layer loads are exerted uniformly on the bedrock through the unconsolidated confined aquifer, making the load keep a constant during the excavation process. 有松散承压含水层时，上覆表土层的载荷通过松散承压含水层均匀地作用于下部基岩上，开挖过程中，基岩顶界面上的载荷基本保持恒定；
The simulation results indicate that the unconsolidated confined aquifer plays a crucial role in the process of load transfer because of its fluidness and replenishment in time. 通过实验结果的对比分析，得出由于承压水的流动性和补给作用，松散承压含水层对载荷的传递起很大作用。
The factors of DLCT model are: (1) depth to confined aquifer, (2) lithology of the aquiclude, (3) continuity of the aquiclude and (4) thickness of the aquiclude. DLCT模型包含有承压含水层埋深、隔水层岩性、隔水层的连续性和隔水层厚度4个因子。
Considering the situation in China, we propose a DRTA model for vulnerability assessment of unconfined aquifer, and a DLCT model for vulnerability assessment of confined aquifer. 根据中国情况，提出用DRTA模型评价潜水的防污性能，用DLCT模型评价承压含水层的防污性能。
However, the similar simulation shows that, without the unconsolidated confined aquifer, the load exerted on the bedrock decreases obviously during the excavation activity. 无松散承压含水层时，基岩顶界面上的表土层载荷随煤层开挖而显著降低。
With a specially designed experimental instrument, the mechanism of load transfer within an unconsolidated confined aquifer and its effect on compound breakage of key strata have been studied. 摘要采用专门设计的物理模拟试验装置及数值模拟试验方法，就松散承压含水层的载荷传递机制及对覆岩关键层复合破断的影响进行深入研究。
Time is sometimes called the fourth dimension. 时间有时被称为第四度空间。
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 a specially designed experimental instrument,the mechanism of load transfer within an unconsolidated confined aquifer and its effect on compound breakage of key strata have been studied. 采用专门设计的物理模拟试验装置及数值模拟试验方法,就松散承压含水层的载荷传递机制及对覆岩关键层复合破断的影响进行深入研究。
This paper investigates a coastal aquifer system consisting of a confined aquifer from up and down by two semi-permeable layers.The suboutcrop of the aquifer is covered by a silt layer. 摘要通过对一个滨海多层含水层系统的考察，该含水层系统由上、下弱透水层和介于中间的承压含水层组成，海底露头处被淤泥层覆盖。
