A finite element numerical model for arch dam-gravity pier-foundation system was established to evaluate the effect of high gravity piers on the stress, deformation and anti-sliding stability of Sizhai arch dam, taking the following factors into account, such as the possible elastoplastic deformation of foundation rocks and the nonlinear interaction between the interfaces of gravity pier-dam foundation, the joint surfaces beneath the right bank, and the interfaces of arch dam-gravity pier.

摘要为评价高重力墩对四寨拱坝的应力变形和抗滑安全的影响，建立了拱坝－重力墩－地基系统的有限元数值模型，其中考虑重力墩－基础、右岸夹层和拱坝－重力墩等交界面的非线性相互作用，以及基岩材料的弹塑性变形行为。

The study result indicated that the free vibration of the dam will be affect by opened hollow and pier added on dam.

研究表明考虑孔口和闸墩对大坝的自振特性有一定的影响。

According to the bridge pier, the in-situ check dam and four protection measures, seven sets of experiments were carried out.

针对桥墩形状、既有固床工及四种保护方案，进行了七组水工试验，加上模拟上游进砂的情形一组，总共为八组试验。

In order to study local scouring field near the pier with sediment control dam ,the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek.

采用Sontek公司声学多普勒测速仪对有拦沙坝防护的模型桥墩附近流场进行了精细测量，对桥墩冲刷坑内三维流速分布进行了分析，给出了冲刷坑内三维紊动特征量的分布，分析研究了有拦沙防护坝时桥墩局部冲刷的三个新特点，提出了拦沙坝的适用条件。

For vibration mode-shape, this affect is moreseverity on high rank stage vibration than low. With opened hollow and pier added on dam,the frequency of vibration decline.

对于振型而言，这种影响对低阶振型比高阶振型大，考虑孔口和闸墩后，大坝的自振频率有所降低；在低阶振型中有一部分的排列顺序发生了变化，但这些变化不致使大坝的动力特性发生显著的改变。

In order to study local scouring field near the pier with sediment control dam, the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek. This paper analyses the velocity distribution in the scouring pool of pier and takes turbulent strength distribution in different direction. Three new characters for the local scours of piers with the sediment control dam are analyzed and the dam's applicability is brought forward.

采用Sontek公司声学多普勒测速仪对有拦沙坝防护的模型桥墩附近流场进行了精细测量，对桥墩冲刷坑内三维流速分布进行了分析，给出了冲刷坑内三维紊动特征量的分布，分析研究了有拦沙防护坝时桥墩局部冲刷的三个新特点，提出了拦沙坝的适用条件。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
