介绍在建中日本最大规模的全库铺设沥青混凝土面板水库的抗震设计。基于水库所处的地形、地质及堤体填筑条件,首先对水库整体进行三维有限元动力分析,从总体上掌握水库的地震反应特性;然后对变形较大的断面进行详细的二维动力分析,获得面板的最大动应变。同时,通过大量室内试验,确定满足施工要求的沥青混凝土配合比及其物理力学特性。根据面板的材料特性及其构造特点,提出二级抗震设防的极限状态设计法,并对该水库面板的抗震性能进行校核。
Describe the seismic design of laying the largest asphalt concrete tank reservoir in Japan. Based on the topography, geology and dike filling conditions in the reservoir, the three-dimensional finite element dynamic analysis of the reservoir is first carried out to grasp the seismic response characteristics of the reservoir as a whole. Then a detailed two-dimensional dynamic analysis of the deformed section is carried out. , Get the maximum dynamic strain of the panel. At the same time, through a large number of indoor tests to determine the construction requirements to meet the asphalt concrete mix and its physical and mechanical properties. According to the material properties of the panel and its structural features, the limit state design method of the second-level seismic fortification is proposed, and the seismic performance of the reservoir panel is checked.
