摘要:
针对引调水工程的风险分析较少涉及调水水库和受水水库防洪风险分析的不足,本文以罗田县新义引水工程为例,以最高洪水位和最大泄流量为评价指标,对调水水库和受水水库的防洪风险进行了评估,提出了引水后受水水库的防洪调度规则,以降低跨流域调水工程对受水水库防洪的不利影响。研究结果表明,新建新义引水工程,调水水库天堂水库因汛期调出水量2500万m3,不会降低调水水库原有的防洪标准;受水水库跨马墩水库虽汛期引入水量2500万m3,但采用正常溢洪道、泄洪洞、发电洞均参与泄洪的防洪调度规则进行防洪调度,相比引水前仅考虑正常溢洪道参与泄洪的防洪调度规则,不会降低受水水库原有的防洪标准。

Abstract: Aiming at the shortage of risk analysis for flood control of water diversion and recipient reservoirs in water diversion project, risk analysis for flood control is evaluated by high flood water level and maximum flood discharge in Xinyi water diversion project. Flood operating rules are proposed in order to reduce the negative effect by water diversion project. The results show that water volume of 25 million m3 can be transferred by water diversion reservoir without reducing originally flood prevention standards of Tiantang reservoir. Besides, water volume of 25 million m3 can be accepted by water recipient reservoir with new flood control operating rules considering normal spillway, flood discharging tunnel and power generation tunnel. The new flood control operating rules do not reduce originally flood prevention standards of Kuamadun reservoir, comparing with the originally operating rules considering normal spillway.
