中小型水利工程设计风速取值探讨

风速作为计算水利工程波浪爬高的重要参数之一,可以通过专门设置观测点取值。对于一般未设立具体观测站点的中小型水利工程,则多根据类似工程或经验取值。由于未考虑具体工程特点且规范依据不充分,其参数取值具有一定的随意性。以台州市为例,结合相关规范,推导了工程设计的风速取值,其参数符合各项规范要求,较仅凭经验取值更加合理,基本能够满足设计要求。对其他地域的类似工程具有参考价值。

Discussion on wind speed value in small and medium -sized hydropower projects

As one of the most important parameters for calculating the wave run-up height of hydropower projects,the wind speed value can often be obtained by setting special observation station,while it can be acquired from similar projects or experiential value in case of the small and medium-sized hydropower projects,as a result,the parameter values are usually arbitrary without the consideration of characteristics of the specific project and lack of sufficient specification basis.Taken Taizhou as an example,the designed wind speed values are deduced based on the relevant specifications,the results show that the values are more accurate than the experiential ones,and can meet the requirements of specifications and design.In addition,it has the reference for similar projects of other regions.
