坝

To insure the safety of the oil-pipe during the sluice of Tangjiashan Barrier Lake, calculated the erosion depth of the FU river cross section under the three possible dam-break types.

为了确保唐家山堰塞湖泄洪排险过程中输油管道的安全，对堰塞湖可能出现的三种溃坝方案中输油管道涪江穿越断面的冲刷深度进行了计算。

On the bias down by the north end, you got that?

斜插到坝的北端，听明白了吗？

In order to improve the convergence of the back analysis of the rock-fill material parameters, four improved PSO methods have been proposed in this paper. Two are convergence improved PSO, and the others are the PSO based on multi-objective problem.

为提高标准微粒群算法在堆石坝坝料参数反演分析中的适应性，本文采用收敛性改进的微粒群算法和基于多目标问题的微粒群算法，详细阐述了算法的改进原理。

To analyze the feature of dam-break flow in natural channel bends,channel-fitted orthogonal curvilinear coordinate system is established and two-dimensional shallow water equations are derived in this system through coordinate transformation,simplification and depth integration.

为分析溃坝波在天然弯曲河道中传播的特点，建立了跟踪河道走向的正交曲线坐标系，并通过坐标变换、简化和水深积分推导出了曲线坐标系下的二维浅水方程。

The material job and main conclusion are as follows:(1) A simple boundary orthogonalization procedure independence grids generation method is put forward on the base of algebraic grid generation method; Data structure and computational model on interface are established aiming at blocks of structured grids.

本文针对粘流场数值模拟技术的研究现状和发展动态作了比较全面的回顾与展望，重点研究了网格生成技术、数值求解技术、湍流模型技术和动边界模拟技术，在此基础上建立了模拟自由面湍流场的数学模型，并成功地应用到二维溢流坝和带闸墩的三维溢流坝过坝水流的数值计算。

On the basic of above job a mathematical model of simulation turbulent flow with free surface is established and triumphantly applied to numerical computation on 2D spillway and 3D spillway with frusta of brake.The material job and main conclusion are as follows:(1)A simple boundary orthogonalization procedure independence grids generation method is put forward on the base of algebraic grid generation method; Data structure and computational model on interface are established aiming at blocks of structured grids.

Some flooding from that overspill results—but not as much as if the spill were allowed to erode and destroy the levee itself.

这样虽然有一些河水漫出堤坝，但造成的损失会远远小于由于土坝在水流侵蚀下而垮塌产生的后果。

REPEL is made of the same material as PLUG, but instead of being thrown into the water and carried to its destination by the current, it is laid out flat on a levee that is in danger of being overtopped and thus eroded by the river it is supposed to contain.

它与第一种装置使用同样材料制作，但不是要把它投入河中由水流带到裂口处。一旦河水猛涨漫过堤坝就会对泥土坝造成冲蚀，危及堤坝的安全。此时可以把REPEL铺在堤坝顶上保护堤坝。

Programs are worked out and used for calculating overtopping and instability fuzzy risk of the Cheng Bi He Reservoir.

编制了电算程序，具体对澄碧河水库进行漫坝模糊风险和坝体失稳模糊风险计算。

He was always very intellectual in every subject, but his true pa...

他总是非常的智力在每一个主题，但他真正的坝。。。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
