摘　　要：昆明春之眼商业中心项目按计划一期工程投入9台塔式起重机,其中1号ZSL2700起重机最大起重量为100 t。根据现场实际情况,本着节约工期和成本的原则,利用现有不对称布置的工程桩做塔式起重机基础桩,在控制承台截面的前提下,通过设计超大截面暗梁,满足塔式起重机最不利工况条件下的最大弯矩。此做法在技术可操作性和经济性方面具有很大优势。Phase I of Kunming Eye of Spring Commercial Center project plans to use nine tower cranes,among which No.1 ZSL2700 crane has a maximum lifting capacity of 100 t.Based on the principle of shortening construction period and saving construction cost,practical conditions were considered to use the existing asymmetrically-arranged engineering piles as tower crane foundation pile,design hidden beam with super-large section under precondition of controlling the bearing platform section,and satisfy the crane tower’s maximum bending moment under the worst service condition.This method has obvious advantages on technical feasibility and construction cost.
