变断面U形壳槽设计速算法

The rapid calculation method on the U-shape shell chamfer design of variable cross section

在保证精度，满足规范规定的前提下，根据文内提供的在一定变化范围内的各种表格，如水力计算表，壳槽特性表，纵向应力系数表，纵向配筋系数表，利用这些表格进行设计工作，就是壳槽设计速算法。对已具备基本资料（如设计流量，每节壳槽长度等资料）的变断面Ｕ形壳槽，用本文提供的速算法进行设计，可使繁杂的计算得到很大的简化，使设计者能迅速完成设计工作。

The ranid calculation method of the shell chamfer is that some tableswhich is provided iu this paper,such as the table of hydraulic calculation,thecharacteristic table of shell chamfers, the coefficent table of longitudinal str-ess.the coefficient table of longitudinal located reinforcemeut,is used for thepurpose of designing the shell chamfer. These tables have a certain range of var-iation. If this method should be used to design the U-shape shell chamfer of var-iablc cross section which had some fundamental data such as given flow data fordesign, the shell chamfer length of every stage,the complicated calculation wou-ld be simplified grcatly. Then,the designers can finish their work quickly.
