薄弱地下室底板上塔吊基础的设计与施工

Design and Construction of Crane Foundation on Weak Basement Floor

塔吊基础形式的确定主要考虑工程地质、荷载、塔吊稳定性、现场实际环境条件、技术经济指标等因素,在实际工程中应用需考虑的因素更多也更复杂。本文介绍某项目在薄弱地下室底板上设置塔吊基础,要求施工和使用过程中不能对底板结构造成损坏,通过分析提出一种能满足使用功能、安全、施工工期短、相对较经济的塔吊组合式基础并得到成功应用。

To determine the form of Crane foundation,basis primarily on factors engineering geology,load size,crane stability,the actual site environmental conditions,technical and economic indicators. There are various application conditions. In practical engineering applications,the crane is determined based on the factors to be considered even finer and more complex. This paper studied the contents of the basic problems is to set the crane on top of the weak basement floor,requiring crane foundation can not cause damage to the floor structure in the construction and use. Thus,one can meet the security,functionality and reasonable economic crane foundation is designed and successfully used in the actual project.
