曲墙式混凝土衬砌水窖对称面内轮廓线的选形方法

Selection of curved wall lining concrete water cellar's inner outline in symmetry plane

针对传统水窖对大面积集雨需要的局限性,设计了一种曲墙式混凝土衬砌新型水窖,并提出了由集雨量准确确定出其对称面内轮廓线形状的设计计算方法.在设计过程中,根据相关规范确定出该水窖的各个控制点,利用控制点参数建立了水窖对称面内轮廓线的控制方程,最终采用二分法求解出该水窖对称面内轮廓线的形状.算例表明:提出的选形方法可用于实际工程问题的设计计算.对该新型水窖的对称面选形方法的研究,将为今后大面积雨水积蓄设施的设计提供一定的依据.

As a solution to the limitation of traditional water cellar which can＇t satisfy the request of large-scale rainfall collection, the article puts forward a design of a new curved wall lining water cellar with concrete and a method which determines its inner oul：line in symmetry plane according to rainfall collection. In the designing process, each control point, by which the inner outline controlling equation was established so as to define the inner line shape using the Dichotomy. The results showed that the selection method could be used to design and calculate the practical engineering problems. This study on the selection method of this new water cellar＇s inner outline will provide certain basis for the design of big area rain saying facilities.
