摘要
采用三维仿真材料结构模型试验，研究了高坝洲水电站预应力混凝土蜗壳在预应力、竖向荷载、内水压力及温度荷载作用下的应力分布情况，论证了在混凝土蜗壳这一结构复杂、限裂要求高的建筑结构中采用预应力先进技术的必要性、可行性和优越性。
By employing the three-dimensional model of the emulation material structure, the stress distributions on the pre-concrete scroll case at the Gaozhou Hydropower Station are studied under the actions of the pre-stress, vertical load, inside pressure and the temperature load. The authors of the paper demonstrate the necessity, feasibility and advantage for using the advanced pre-stressed technique in the concrete scroll case that is complicated and requires strictly the limitation of cracks.
