地基土上水工建筑物的抗滑动稳定

利用基坑内压板抗滑动试验成果,确定地基土抗滑动承载能力。采用地基土承受偏心荷载的最大压应力σmax控制地基土与压板的位移和抗滑动形式,可产生3种不同的最大位移面,形成8种抗滑动形式。根据地基土承受的最大压应力,提出定量确定地基土与压板抗滑动的计算摩擦阻力的方法和设计抗滑动的4个数值计算公式,分析预测可能发生的最大位移面和抗滑动形式。对三河闸、高良涧进水闸、三河船闸3座已建水工建筑物的抗滑稳定性分析表明,计算成果符合实物工况。     

冰在斜面结构上的纵横弯曲破坏分析

说明了在冰排与斜面结构相互作用分析中应当考虑水平力的附加弯矩作用，按照纵横弯曲模式进行了冰荷载和冰的断裂长度分析，给出了简化的公式和算例。结果表明，上述考虑将使冰力和冰的断裂长度趋于减小。预测的断裂长度与现场观测结果大致吻合。     

Method of calculating the stability of rock slopes of hydraulic structures

Conclusion The proposed methods of calculating and analyzing the stability of rock slopes make it possible to obtain reliable results with consideration of the possible character of failure and degree of reliability of the initial information. These methods were widely used in practical calculations of the stability of rock masses and slopes when planning stabilization measures in the reservoirs of the Tolorossy and Zaramag dams (Armenian branch of Gidroproekt), Akhuryan dam (Armenian State Institute for the Design of Water-Management Structures), when investigating and designing the lock of the Dnepr-2 hydroelectric station (Ukrainian branch of Gidroproekt), and when investigating and designing the Middle Enisei hydrostation, Khudofera hydrodevelopment, Konstantinovka hydrostation and Tashlyk pumped-storage station, Southern Ukraine power complex, etc.Translated from Gidrotekhnicheskoe Stroitel'stvo, No. 1, pp. 26–29, January, 1982.     

黄河下游防洪新方案的初探

通过对黄河５８型下大洪水各级频率的洪峰过程的洪水推演、分洪计算表明，利用温孟滩区、沁南洼地和长垣滩区蓄洪，可以削减特大洪水时花园口和孙口的洪峰流量。极大地减轻了洪水对大堤的压力，以较小的投入和淹没损失，取得较大的防洪效益。因此，利用滩区削峰滞洪是一种有效的措施。     

Impact of human activities on the evolution of the Romanian Black Sea beaches

The Romanian Black Sea coastal zone is divided into two main sectors. Sediment characteristics and general transport patterns are presented for each of them. The human activities influencing the beaches’ evolution are depicted and the present‐day impact described.
