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作者簡介：侯勝利，碩士，副總工程師，一級注冊結(jié)構(gòu)工程師，Email：sheng-li.hou@arup.com。參考文獻(xiàn)［1］袁志英, 郝江南. 貴陽地區(qū)基本地質(zhì)環(huán)境和主要巖土工程問題綜述［J］. 地球與環(huán)境, 2005, 33（IS）: 251-254.［2］梁黃顧建筑師(香港)事務(wù)所有限公司.建筑設(shè)計(jì)文件報告［R］. 香港，2012.［3］DB 22/46—2004 貴州建筑巖土工程技術(shù)規(guī)范［S］. 貴陽：貴州省建設(shè)廳, 2004.［4］JGJ 3—2010 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］. 北京:中國建筑工業(yè)出版社,2011.
