在泥沙方面,研究泥沙起动,淤积物干容重的变化,冲刷条件下的床面形态和减少引航道淤积的措施,并尝试应用模糊数学和重正化群的概念对上述问题进行分析。针对通航建筑物,研究了船闸水力学、大坝溢洪道泄水对通航的影响、小型船模和船闸运用模拟设备。对180m高边坡,针对开挖卸荷引起的岩体变形,研究了粘、弹、塑性的影响,不恒定渗流以至流变特性。对锚固也做了研究。在材料方面,研究了超细水泥、补偿混凝土和高粉煤灰HPC,探讨了更耐久而抗裂的水泥。优化了多点监测系统,以便有效而及时地测取资料并提高信息分析水平。编制了混凝土高坝仿真并层反馈计算的程序。
In the aspect of sediment, this paper studies the start of sediment, the change of dry bulk density of sediment, the shape of bed under scour and the measures to reduce siltation of approach channel. At the same time, the concept of fuzzy mathematics and renormalization group is used to analyze the above problems. In view of navigation buildings, the research on the effects of ship lock hydraulics, spillway spillway on navigation and the simulation of small ship models and locks is carried out. For the 180m high slope, in view of the deformation of rock mass caused by excavation unloading, the effects of viscoelasticity, elasticity and plasticity, unsteady seepage and even rheological properties are studied. Anchoring has also been studied. In terms of materials, ultrafine cements, compensated concrete and high fly ash HPCs were studied, and more durable and crack resistant cements were explored. Multi-point monitoring system is optimized for effective and timely data acquisition and information analysis. Compile the program of concrete dam simulation and layer feedback calculation.
