Based on the comprehensive analyses of the complex site geological conditions, location selection of buildings and depth of basement were optimized. The selection of foundation types of twin towers and treatment of karst cave were presented. A detailed analyses of the main design indices of the structure were carried out under the wind load once in 50 years and seismic action, including natural vibration period, shear force, lateral displacement, maximum inter-story displacement angle and overturning moment. The results show that the design of this project can meet the expected seismic performance objectives.Keywords: concrete-filled steel tubular laminated column; karst cave; tube in tube structural system; super high-rise building作者简介：侯胜利，硕士，副总工程师，一级注册结构工程师，Email：sheng-li.hou@arup.com。参考文献［1］袁志英, 郝江南. 贵阳地区基本地质环境和主要岩土工程问题综述［J］. 地球与环境, 2005, 33（IS）: 251-254.［2］梁黄顾建筑师(香港)事务所有限公司.建筑设计文件报告［R］. 香港，2012.［3］DB 22/46—2004 贵州建筑岩土工程技术规范［S］. 贵阳：贵州省建设厅, 2004.［4］JGJ 3—2010 高层建筑混凝土结构技术规程［S］. 北京:中国建筑工业出版社,2011.
