【摘要】 牛栏江-滇池补水输水工程线路分别穿越云南省小江活动断裂带中段的东支和西支,两断裂均为全新世活动断裂,构造变形量大、地震烈度高。在分析小江区域活动断裂带对输水工程影响的基础上,提出了过小江区域活动断裂带的输水建筑物特殊结构方案,并采用数值分析方法深入研究了结构方案适应较大构造变形的能力和抗震性能。结果表明,该结构方案可以较好适应活动断裂带的大变形和强地震作用。更多还原

【Abstract】 Niulan River-Dianchi Lake Water Supplement Project crosses the east and west branches of the middle section of Xiaojiang active fault zone in Yunnan Province,which are holocene active fault with large structural deformation and high seismic intensity.On the basis of analyzing the influence of active fault zone in Xiaojiang Region on the water conveyance structure,the special structural scheme for the water conveyance structure crossing the Xiaojiang active fault zone is proposed.For the structural scheme,its ability of adapting to large structural deformation and the seismic behavior are further studied.It shows that this scheme can adapt to the large deformation of the active fault zone and strong seismic action.更多还原
