For the arch dam which reservoir has no suitable breach to build lasher and has mass flood discharge, opening large orifice for flood discharge has great advantage.

對(duì)于庫(kù)區(qū)無(wú)適宜埡口可興建泄洪道，而泄洪量又較大的拱壩工程99九色视频在线观看，在壩身中開設(shè)大孔口泄洪具有顯著的優(yōu)越性久久激情免费视频。

In This paper, it is discussed that how to establish risk-analysis indexes system of flood discharge structures for concrete dam based on lack of monitoring data, and how to measure the flood discharge risk furtherly.

因此，本文就如何在監(jiān)測(cè)資料缺乏的情況下建立混凝土大壩的風(fēng)險(xiǎn)指標(biāo)體系進(jìn)行了探討18岁未进入黄片，重點(diǎn)對(duì)泄洪系統(tǒng)中的水力風(fēng)險(xiǎn)進(jìn)行了研究特级毛片在线视频免费观看。

Then, transmission relationship between frequency for maximum flood discharge in a yearand frequency for every flood in this year was established. And based on the risk rate ofdynamic controlling reservoir water level in flood season defined by Prof. B.D Wang andmaximum entropy model of forecast error distribution, the definition of risk rates when usingflood forecast or combination of flood forecast and precipitation forecast to control limitwater level in flood season were difined. And their corresponded calculation methods weregiven as well in this dissertation.
