  high arch dam
Between the years of 1981 and 1983 a 45 metres high arch dam was constructed for irrigation purposes at the Gorgol-Noir, a tributary of the Senegal River, in the semi-desert zone of southern Mauritania (Sahel).
      
The earthquake response of a 278m high arch dam is analyzed, and the results show that the strain-rate effects become noticeable in the inelastic range.
      


The analysis of stability of the arch dam abutments is important and complicated. In this paper a study is presented on the stability of a high arch dam and its abutments by geomechanical model test, allowing for the interaction of the dam and the treated abutments. The characteristics of test, some problems in model design, the safety factor and the mechanism of rupture of the dam and abutments are also described.

拱坝坝肩稳定是目前高拱坝设计中的一个重要而复杂的问题。近年来发展起来的地质力学模型试验是研究拱坝坝肩岩体稳定的有效途径。本文介绍了国内某大型重力拱坝枢纽整体抗滑稳定三维小块体地质力学模型试验研究实例,其中包括试验的特点、模型设计问题以及部分试验成果,分析了拱坝及进行处理后的两岸坝肩山体在水位超载条件下的安全度及其破坏机理。

LONGY ANGXIA is a gorge of complicated geologic condition situated in the upper reaches of the Yellow River. LONGY ANGXIA HYDRO includes a high arch dam and a large reservoir. At present, its electric power generation is the greatest in China's hydro station. Together with internal observation, adequate items of external observation are disposed for safety surveillance. This paper deals with arrangement of observation, observation results and author's analysis of four main items of external observations, i. e., horizontal disPlacement of dam area, vertical displacement of dam area, inclination of dam body and crevice of dam body.

龙羊峡电站是黄河上游第一个梯级电站,也是中国大陆目前大坝最高、库容最大、单机容量最大的水电工程,地质条件又极为复杂,为了监测大坝安全运行情况,在坝体和两岸布置了众多的外部观测项目。本文介绍了龙羊峡电站外部观测项目的布置以及在拱坝观测中采用的新方法、新设备。

The foundation of an arch dam often contains soft seams or consists of rock strata with diffrient properties. Therefore photoelastic stress analyses of an arch dam on non-homogeneous foundation are improtant and complicated. In this paper the stress analysis of a high arch dam together with its complex foundation by using photoelastic study of a three-dimensional model is presented. Some problems are described briefly such as casting combined model and loading analogy on it. The performance of the dam...

The foundation of an arch dam often contains soft seams or consists of rock strata with diffrient properties. Therefore photoelastic stress analyses of an arch dam on non-homogeneous foundation are improtant and complicated. In this paper the stress analysis of a high arch dam together with its complex foundation by using photoelastic study of a three-dimensional model is presented. Some problems are described briefly such as casting combined model and loading analogy on it. The performance of the dam and the stress distribution in the dam under hydrostatic water load and silt pressure have been analyzed. Besides, the effects of variation in elastic modulus of foundation, asymmetry of the elastic moduli and existence of low modulus zones in the foundation on the stress in the dam are also disrcussed.

非均质地基上高拱坝应力分析是目前坝工设计中的一个重要而又复杂的问题。本文介绍了国內某大型重力拱坝光弹性整体模型试验研究实例,其中包括变弹模组合模型浇制、水砂压荷载模拟及主要试验成果,分析了在水压和泥砂压力作用下非均匀基础上高拱坝的受力特点和工作状态,论述了基础弹模变化和不对称性以及局部低变模区的存在对坝体应力的影响。
