南水北调中线陶岔渠首枢纽工程是经国务院南水北调办批准建设的国度大型水利工程，是南水北调中线一期工程的重要状干部分，渠首枢纽工程既是南水北调中线输水总干渠的引水渠首，也是丹江水库的副坝，工程设计为新址重建，并增建发电站，建筑物主要有引渠、重力坝、引水闸、消力池、电站厂房和治理用房等。

Then the solid geometry model is entered into ANSYS to do the pre-treatment of FEM. It is disassembled by hexahedron elements.

将几何模型导入到ANSYS中做有限元分析的前处理，采用六面体单元对重力坝进行网格划分。

This paper studies the stress of gravity dam heel with careful numerical simulation, and analyses the effect of the variety of the elastic modulus of homogeneous or non-homogeneous foundations on the principal tensile stresses of gravity dam heel. The conclusions are as follows:① When the elastic modulus of homogeneous dam base and variated element in the critical place is changed with the same the fluctuation, the effect on the dam heel stresses caused by the latter is much more prominent than the former one.

本文通过精细网格模拟研究了重力坝坝踵应力情况，就均质坝基和非均质坝基弹模变化对坝踵主拉应力的影响，得出了如下结论：①均质坝基弹模与非均质坝基敏感区域的变异单元弹模变化相同的幅度，非均质情况引起的坝踵应力的变化远大于均质情况。

The influence of the interaction on the mode shapes of the dam is also analyzed. Based on the above analyses, two modified models, which are massless damping foundation and part of mass foundation, are presented to simulate the dam--foundation interaction mechanism. A new method to form the non-proportional damping matrix is proposed.

在此基础上，为了更好地模拟坝—地基相互作用的机制，提出了两种改进的地基计算模型：无质量有阻尼地基模型和部分有质量地基模型，建立了形成体系非比例阻尼矩阵的方法，并用来分析了相互作用对重力坝的地震反应的影响。

From the point of practice, the massless foundation model is applied for problem of the dam--foundation interaction. The regularity of the natural frequencies of the dam varying with the boundary size of the foundation is studied under various foundation conditions, and then the rational foundation size is decided.

从实用的角度出发，利用无质量弹性地基模型分析坝—地基相互作用问题，研究了不同地基情况下重力坝自振频率随地基边界范围变化的规律，确定了合理的地基边界范围，并分析了相互作用对坝体振型的影响。

The effect of monolith interaction on the overall dynamic response of concrete gravity dams is investigated.

Research on deep anti-sliding stability and reinforcement of entirety polygonal line gravity dam;2. The 2D Elastoplastic Finite Difference Method is adopted to analyze the deep anti-sliding stability for the dam foundation of Longkou hydropower station factory dam.

采用二维有限差分程序对龙口水利枢纽混凝土重力坝厂房坝段进行深层抗滑稳定分析，采用强度折减方法，根据特征点位移突变临界破坏判据和止水帷幕部位夹层错动量达到1mm临界破坏判据分别得出了厂房坝段的两个深层抗滑稳定安全系数。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
