杭州大会展中心结构设计综述

Structure design summary of Hangzhou Grand Exhibition Center project

杭州大会展中心项目是重要的地标性建筑,体量大、体型复杂。其既有典型会展项目的超长、大跨、大悬挑等传统结构特点,也存在各类新颖独特的结构形式,甚至有各结构形式杂交融合的新型特点。项目内含运营地铁、在建地铁、拟建的市政桥隧,地下空间多元复杂,是集地下商业、市政交通、地铁保护为一体的大型会展类项目代表。本文主要介绍杭州大会展项目结构总体设计思路、结构体系、地基基础概况等;明确该项目的设计标准、参数选取、设计关键技术措施等,旨在为此类项目的结构设计提供有益的借鉴参考。

Project of Hangzhou Grand Exhibition Center is one of the most important landmarks with large space and complex geometry.This building not only has the traditional structure characteristics with long length,big span,large cantilever of typical exhibition projects,but also exists various new and unique structure style,even presents new features of blended structure styles.Moreover,operating subway,subway under construction,proposed municipal bridge and tunnel are included in this project,which make the underground space multiple complex.This project is a representative grand convention and exhibition project with the function of underground commercial,municipal transportation and subway protection.This paper focuses on the overall design of the structure,structure system,building foundation and so on,including design criterions,parameter selection,key technical measures of design etc.,so as to provide useful reference for the structural design of such projects.
