saturate ground meaning in Chinese
水涝地
Examples
- And with warm rains melting snow or drenching already saturated ground , the risk of extreme floods will rise dramatically
并且随着暖雨融化冰雪或者下到水量已饱和的地面，大洪水泛滥的危险将急剧增长。 - It is necessary to study the torsional vibrations of foundations on layered saturated grounds , since layered property is one of the main characteristics of grounds
地基土的主要特征之一是成层性，因此有必要研究成层饱和地基上基础的扭转振动问题。 - The main work includes : for the torsional vibrations of a rigid disk on saturated media , first , the dynamic governing equations are solved by the use of hankel transform and the general solutions in the hankel transform fields are formulated . then , considering the mixed boundary - value condition , the dual integral equations of the torsional vibrations of a rigid disk on saturated grounds are obtained , which can be reduced to the fredholm integral equations of the second kind and solved by numerical procedures . consequently , the dynamic compliance coefficient curves and the torsional angle amplitude curves versus the dimensionless frequency are presented and contrasted to that of the elastic one
在前人研究的基础上，本文基于陈龙珠等曾提出的一组实用饱和土波动方程，用解析或半解析的方法首次较系统而深入地研究了饱和半空间地基与基础的扭转振动问题，主要工作有：对于饱和地基上刚性圆板的扭转振动，作者首先采用hankel变换求解了动力控制方程，得到了该控制方程在hankel变换域内的通解，然后由混合边值条件建立了饱和地基上刚性基础扭转振动时的对偶积分方程，并将其化为易于数值求解的第二类fredholm积分方程，用数值方法计算了基础的动柔度和扭转角幅值与振动频率的关系曲线，并将其与单相弹性介质情况进行了对比分析。 - Then , considering the existing of the ground water , we can treat the soil layer below the water level as the saturated one and the soil layer above the water level as the single - phased elastic one . using this model , the torsional oscillations of the rigid disk resting on the saturated ground with an elastic layer is studied and the effects of the elastic layer on the foundation ' s vibration are discussed
接着，考虑到地下水的存在，将地下水位以下的土层视为饱和土，地下水位以上的土层视为理想的单相弹性层，按此模型研究了上覆单相弹性层的饱和地基上刚性基础的扭转振动问题，分析了弹性层的存在对基础振动的影响。 - Finally , the torsional vibration of a rigid disk resting on the saturated grounds under the general torque is primarily discussed by the means of laplace - hankel transform . the general solutions of the torsional moment , stress and displacement are given and the numerical solutions in special cases are also obtained
最后，本文还采用laplace - hankel联合变换技术初步分析了在一般动扭矩作用下饱和地基上刚性圆板的扭转振动问题，给出了扭矩、应力和位移的通解，并给出了特例情况下的数值解。
