Based on testing datas in worksite and engineering practice,this paper mainly discussed strata damage movement characteristic, rock properties of weathered zone, qualitative and quantitative analysis of the law of coal layer safety extraction in weathered zone when the coal layer is extracted in efflorescent oxygenized belts.

根据现场观测资料和工程实践，着重论述了风氧化带内煤层开采时覆岩破坏移动特征，风化带岩石属性和风氧化带内煤层安全开采机理的定性、定量分析。提出了风氧化带煤层开采无垮落带；受采动影响后，具阻水和抑制导水断裂带继续发展的双重作用以及移动快、变形大、回宿快、下沉大和适当加大开采厚度等新观点

Since the Three Gorges reservoir began to impound in 2003, reservoir water table will fluctuate from altitude of 175 m to 145 m.

三峡水库蓄水后，库水位将在 14 5～ 175m范围内波动，动水压力和水的软化作用是滑坡失稳的主要因素。

Based on the assumption of incompressibility of reservoir water,the basic formulae for calculating hydrodynamic pressure and the added mass matrix are derived.

在库水不可压缩假定的前提下推导了坝面动水压力与附加质量矩阵的基本方程。

On the assumption of incompressibility ofreservoir water, the added mass matrix was also derived. Numerical examples of gravity damsand arch dams show that this approach is simple, effective and appropriate for engineeringpurpose.

并在库水不可压缩的前提下，推导出了基于SBFEM的动水压力附加质量矩阵计算公式，与原有的工程中普遍采用的其它附加质量计算方法相比，计算精度和效率均得到很大提高，比较适合实际应用。

It is the Water of the Great Cause, motionless.

这是第一因的水，是静止不动的水。

When wind vibration branches and leaves, when the cloud has inundated the top of the head, when thin Shui Qingliu, when outside the window mullion the potted flower stretches, in same month mountainside, galaxy motionless day like element water, even if in a piece of disorderly time, my heart bees in no position one remembers intermittently.

当风抖动枝叶，当云漫过头顶，当细水轻流，当窗棂外盆花舒展，当月上山腰，星河不动天如素水，即使一片杂乱的时光中，我心都无由地一阵阵想起。

In order to accurately calculate the mining induced subsidence in thick alluvium areas so as to decrease the mining damage and environment disruption,the calculation of surface subsidence caused by water loss of clay was discussed based on probability integral method and used in a real case.

为了更加精确地计算厚冲积层矿区的煤矿开采沉陷问题，减小采动损害与环境破坏，基于煤矿开采沉陷计算的概率积分法，探讨了由于黏土体失水引起的地表沉陷计算问题，推导了黏土体失水引起的地表下沉计算公式，并应用于煤矿实际地表沉陷，加以分析论证。

The interactions among large air voids, the dynamic hydraulic pressure, the non-uniformly distributed load, the overload, the environment condition and the material lead to the deficiency of the adhesion between asphalt and aggregate. The immigration of the asphalt leads to the new bleeding and inside raveling. The pumping and settlement occurred once the water penetrates the whole asphalt layer.

大空隙率、动水压力、荷载的非均布、超载以及气候条件与路面材料的相互作用造成了沥青与集料粘附性的相对不足，面层内部沥青膜剥落后向上部迁移，这是新泛油、内部松散的产生机理；更为严重的情况下，外界水直接贯穿沥青面层对基层顶面的冲刷将诱发泛浆和沉陷。

To obtain the approximate solution, the pressure acting on the gate is divided into two parts, one is the fluctuating pressure of the flow underneath the stationary gate, which is investigated with experiment; the other is the hydrodynamic pressure due to the vibration, which is equivalent to the attached mass matrix, damping matrix and stiffness matrix of the equation.

为了获得方程的近似解，本文将作用在闸门上的水动力荷载分为两个部分，一是闸门无振动时的水流压力，用水力模型试验测定；二是由于闸门振动引起流场扰动的动水压力，通过运动方程中的附加质量阵，附加阻尼阵和附加刚度阵来等效。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
