produce of dam

The thermo stresses in the concrete dam will produce because of changing of weather temperatures.

由于气温的交替变化,处于寒区的混凝土大坝必然产生温度应力.

But after dam body opened, weakened the spot structure integrity. The orifice surroundings will produce easily disadvantageous concentrated stress or bigger tensile stress, and crack at corner and edge of orifice.

但坝身开孔后削弱了该部位结构的整体性，孔口周围易产生不利的应力集中或较高的拉应力，在孔口角缘处，易产生裂缝。

Around the country, Chinese contractors have been building roads, telecommunications infrastructure and, at the headwaters of the Blue Nile in the north, a dam to produce much-needed power.

而在埃塞俄比亚全国，中国承包商建设着公路和电信设施，并将在北部的青尼罗河（Blue Nile）上游建造一座大坝，提供埃塞俄比亚急需的电力。

Just one of the dam's main generators produce 700 megawatts of electricity.

在该大坝中,仅仅一组主发电机就可发电700兆瓦.
