介绍了该超高层建筑的水系统分区、中承压管道设计、电梯井烟囱效应、防排烟设计等。该工程中水系统的承压突破了1．6 MPa，甚至超过了2．5 MPa 而达到3．0 MPa，对管道和管件的强度计算和应力计算提出了新的要求。冬季室内外空气的密度差产生的电梯井烟囱效应会导致超高层建筑首层高区的电梯门难以关闭，简要介绍了该项目采取的技术措施。
介紹瞭該超高層建築的水繫統分區、中承壓管道設計、電梯井煙囪效應、防排煙設計等。該工程中水繫統的承壓突破瞭1．6 MPa，甚至超過瞭2．5 MPa 而達到3．0 MPa，對管道和管件的彊度計算和應力計算提齣瞭新的要求。鼕季室內外空氣的密度差產生的電梯井煙囪效應會導緻超高層建築首層高區的電梯門難以關閉，簡要介紹瞭該項目採取的技術措施。

Presents the vertical zoning of chilled water system,middle-pressure pipe design,stack effect of elevator shaft,and smoke control and exhaust system design.In this project,the working pressure of chilled water system exceeds 1.6 MPa and 2.5 MPa,and reaches 3.0 MPa,which proposes new requirement for strength calculation and stress calculation.For super high-rise building,the air density difference between indoor and outdoor results in stack effect of elevator shaft,which will make the elevator door on the ground floor unable to close.Briefly introduces the technical measures used in the building.
