0 前言 随着建筑业的发展以及建筑技术水平的提高,高层和超高层钢结构建筑工程越来越多。在钢结构工程安装过程中,测量是一项专业性较强且又非常重要的工作。测量精度的高低直接影响到工程质量的好坏,是衡量钢结构工程质量的一项重要指标。 上海浦东国际金融大厦是一座高达226m的超高层钢结构工程,该工程地下3层,地上53层,中央核心筒为劲性钢筋混凝土结构,外围是由19节钢柱组成的钢结构。该工程采用“天园地方”的设计方案,造型新颖、美观,但其结构复杂、施工难度大,安装校正测量精度要求高。核心筒的三次变体和高层栋的倾斜收缩都对测量提
0 Foreword With the development of the construction industry and the improvement of building technology, there are more and more high-rise and super-high-rise steel construction projects. During the installation of steel structures, measurement is a highly professional and very important task. The accuracy of the measurement directly affects the quality of the project and is an important indicator of the quality of the steel structure. Shanghai Pudong International Finance Building is a super high-rise steel structure project up to 226m. The project consists of 3 floors underground and 53 floors above ground. The central core is a reinforced concrete structure and the periphery is a steel structure composed of 19 steel columns. The project adopts the “Tianyuan Place” design scheme, which is novel and beautiful, but its structure is complex and construction is difficult, and installation and calibration measurement accuracy is required to be high. The three variants of the core tube and the oblique shrinkage of the high-rise ridge are all measured.
