This paper discusses some problems which are found to be important in designing the arch dam of the Liv-Hsi-Ho-hydroelectrical power station. The arch dam under discussion has a max. height of 82 m and spans 255. m, situated in a V-shaped valley. It is an overflow arch dam of the various radius and thickness type. The technical design has been nearly finished and the dam is now under construction. The first problem discussed is the investigation of the stability of arch dam under various ioads when the dam is rested on a rock foundation with unexpected jointe and cracks. Methods and formulas for the determination of stability factors are recommended. Then the paper reviews the various methods of stress andlysis of arch dams now in use and finds that the cantilever-arch method (or so called the trial load method) is a suitable one. An amphified procedure is suggested, with this procedure and by means of certain tables of founda- tion and arch deformation constanis, the analysis of stressos and deflections of a circular arch including the effect of foundation deformation can be simplified greately without sacrifyinq dccuracy. The necessdry tables needed in analysis will be presented in an dnother paper. The problems of temperature control and temperature stresses determination are also impor- lant ones in arch dam design and construction. This paper discusses the vdrious principles of temperature control and method of computation, and describes the one accepted in this dam. The priciples of analysis of temperature stresses of arch dams are discussed in detail. Finally the problem of discharginq floods over the arch dam is described in brief. The design work in this respect has not been finished, further investigations and model tests are roquired.

本文旨在论述流溪河拱壩工程在设计中一些主要问题。拱壩最大壩高82公尺,壩顶弧长255.5公尺,位于一V形山谷中。壩体大不同半径和厚度拱壩并采用壩顶溢流形式。工程设计及施工已接近完成。本文首先探讨了拱壩壩头岩基具有节理和裂隙时在不同荷载下的稳定问题。推荐了决定系数的方法和公式。其后就现有的拱壩各种放力分析方法进行了论述并认力悬臂拱法(或称试载法)较为适用。本文对于试载法提出了改进步骤,利用这些改进步骤并借用一定数量的基础和拱圈变形常数表则计算应力分析和包括基础变形的圆拱变位可大大简化并无损其精度。在分析中所需数表将另著文介绍。控制拱壩温度和确定温度应力问题在拱壩设计和施工中也极关重要。本文论述了温度控制的各种原理和计算方法,并描述了本工程所采用的措施。对于拱壩温度应力的分析原理曾加论述。最后曾就拱壩壩顶溢流问题加以简述。有关此项新颖问题的设计,需待进一步研究并进行模型试验。

A log-function extrapolation method has been proposed for the evaluation of successive stability constants from the extraction data.In order to test for the validity of the proposed method,experimental studies were conducted for the determination of the stability constants of the nitrate complexes of thorium by extraction with TBP,and the results were compared with those obtained by OMHH (10).By eliminating two steps of graphical differentiation and integration,the present method is much simpler but more accurate...

A log-function extrapolation method has been proposed for the evaluation of successive stability constants from the extraction data.In order to test for the validity of the proposed method,experimental studies were conducted for the determination of the stability constants of the nitrate complexes of thorium by extraction with TBP,and the results were compared with those obtained by OMHH (10).By eliminating two steps of graphical differentiation and integration,the present method is much simpler but more accurate than OMHH'S method.It may be applied to the determination of stability constants by the solubility method (25),ion exchange method,polarographic and poten-tiometric methods.The theoretical background of the method has also been discussed from the point of view of the first and the second papers of this series (15,16).
