This paper is mainly studied three-dimensional finite element on sluice construction, and established the entire model including sluice pier、 ground、 the floor board、 and the upper frame as a whole body. Through analysing the static and dynamic problems, we can draw the reasonable conclusions.

本文主要研究了空间水闸结构计算的有限元法，将闸墩、地基、底板和上部排架作为一个整体建立空间有限元模型，进行静动力分析，并得出相应合理的结论。

1 Laid on the observation points, the next gate in the first paragraph and the chamber are in side-dock-type pier and construction of a wide bottom seam laid 8 to each end of the settlement within 24 observation points nails; chamber 14 Fu wall segments are in lock wall at both ends of the floor laid four nails into account the settlement of 56 observation points; settlement nail making use of 40cmФ18 rebar welded copper top round hat hemisphere processed, buried, when coupled with oblique bars welded to the end of plate surface layer and vertical reinforcement, the top highlight the concrete surface, about 1.5 ~ 2.0cm in order to guarantee points are solid.

3.2.1观测点的布设上、下闸首及闸室坞式段均在边墩底板及施工宽缝的两端各布设8个沉降钉计24个观测点；闸室14节扶壁段均在闸墙底板两端各布设4个沉降钉计56个观测点；沉降钉的制作采用40cmФ18螺纹钢顶端焊接镀铜半球圆帽加工而成，埋设时配以斜筋焊接在底板面层及竖向钢筋上，顶端突出砼表面1.5～2.0cm左右，以保证点位稳固。

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。

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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
