This paper describes the model test for stability of the Changzhao rubble masonry dam with concrete mortar. During construction it was found that under the foundaton of the dam there were several clayish layers with a lower coefficient of friction sandwiched between the midweathering rock mass. The designers adopted measures of constructing a cut-off trench behind the toe of the dam and using the rock foundation behind it to ensure the stability of the check dam. On models eleven conditions of two types of cut-off trenches were tested. This paper also describes some techniques on experiment upon stability of the Changzhao dam model, such as modes of p(waterpressure on upstream face of dam)-σ(horizontal displacement) curve, the simulation of the model material from the layer and the influence of the primary stress between layer faces, etc.

In this paper, the methods for calculating the effects of comprehensive soil conservation measures on the reduction of sediment yield in large watersheds are summarized, the amount of sediment reduced is estimated, and the factors which would exert influence on erosion control are ana- lysed.Wuding River, one of the large tributaries in the middle reaches of the Yellow River, contributes a great amount of sediment to the main river. Obvious results have been attained by adopting soil conservation measures on large areas of the watershed combined with building reservoirs and check dams in gullies and streams since liberation. According to the analyses of hydrological data and the estimating amount of sediment reduced by soil conservation measures, about 1.8×109 m3 of sediment has deposited in reservoirs and check dams up to 1981, and the amount of sediment entering into the Yellow River has been reduced in an average of l.6×108 tons annually during 1971-1980. Taking into account the decrease of rainfall, the sediment entering into the Yellow River has decreased more than 50% due to the comprehensive control measures.According to the typical analysis of the Dali River watershed located in the rolling loess area, it shows that among the various control measures, check dams are the best, reservoirs come next and the measures of slope control are less for the effects of storing sediment.

本文概括总结了较大流域综合治理减沙效益的计算方法,估算了减沙效益的定量数值,并对影响减沙效益的因素进行了初步探讨. 无定河是黄河中游水土流失严重的一条较大支流.建国以来,采取大面积水土保持和坝库工程控制相结合的治理方法,取得显著成效.本文利用水文资料分析和水利、水土保持措施数量对减沙效益进行估算,截止1981年,坝库共拦沙18亿立米,其中1971~1980年平均每年减少入黄泥沙近1.6亿吨,扣除因降雨量减少对减沙效益的影响,流域内因综合治理减沙效益亦达50%以上.通过对流域内地处黄土丘陵沟壑区的大理河的典型分析表明,在各项治理措施的拦沙效益中,淤地坝最大。其次是水库,治坡措施拦沙效益较小.
