【摘要】 随着城市建设的发展,高层和超高层建筑逐渐兴起,但由于高层和超高层建筑发展的时间相对较短,对其设计计算的理论还不完善,关于其设计的经验较少。尤其对其基础的设计是跨学科的领域,涉及的理论知识方面较广,所以对其的研究有必要更加深入、更加完善。基础是高层建筑的重要组成部分,它占高层建筑造价的25%~40%。因此,根据高层建筑的结构形式和地基的水文地质条件选择合适的基础形式,不仅是保证建筑稳定的基础,也是节省工程造价的有效途径。本文简要介绍了高层建筑的基础类型,及各类型的适用条件、优缺点、计算方法和国内外的发展状况;长春市的工程地质状况和分区;进而对长春市的高层建筑的基础类型的选择给出适用可行的建议。本文还对长春市的一具体高层建筑的基础进行了设计计算,进而对高层建筑的不同基础类型的造价进行对比和优选,从而验证了长春市高层建筑基础类型的地质分区的可行性和正确性。希望对长春市高层建筑的基础选型和优化给出合理性建议,对长春市高层建筑基础的发展做出贡献。更多还原

【Abstract】 With the development of city construction , tall buildings and supertall buildings rise gradually, but because the development time abouttall buildings and super tall buildings is short , the theories aboutdesign and calculation their foundations is not perfect , the experienceabout design foundations is not enough. Above all ,it is a span-subjectdomain and involved theories are wide ,so it is necessary to make thetheories more through and more perfect.The foundation constructureis a important part of tall buildings .itcost 25~40% engineering cost .therefore it is not noly ensure theengineering safe ,but also save engineering cost to make a reasonablechoice of foundation types according to the structure modality andthe hydrogeological conditions of the soils which the foundation in.The text introduces in brief tall building foundation types and theirapplication conditions, long-comings and short-comings, calculationmethods and domestic and foreign development status;the engineeringgeological conditions and geological circumscription subarea;itprovides applied and feasible advise about selection of tail buildingfoundation types accordingly. The text also makes a design on foundations of a tail building inChangchun city and makes contrasts and selection about them. It isfeasible and correct to make geological circumscription subarea abouttail building foundation types in chang-chun city. The text aims toprovide a reasonable advise to make selection about a tail buildingfoundation types in Changchun city and to contribute to thedevelopment of tail building in Changchun city.更多还原
