摘要: 为监测塔式起重机使用过程中的结构安全状态,提高塔式起重机安全技术管理工作质量,首先,根据结构运动状态特征将监测参数分为静力监测参数和动力监测参数2种;然后,提出静力测点和动力测点的选取原则,并给出应力、变形、温度、风荷载、加速度等类型测点的具体布置方法;最后,以深圳乐普大厦服役塔式起重机为监测对象,应用该方法实施塔式起重机结构安全监测。结果表明:各测点监测数据与数值分析结果吻合良好;塔式起重机在使用过程中始终处于较为安全的状态。

Abstract: In order to monitor structural safety status during the operation of tower crane, improve the quality of safety technology management of tower crane, firstly, according to characteristics of structure motion, monitoring parameters were divided into static monitoring parameters and dynamic monitoring parameters.Then, principles of selecting static measuring points and dynamic measuring points were proposed, and layout method of stress, deformation, temperature, wind load, acceleration and other types of measuring points were given. Finally, taking tower crane in service of Lepu building in Shenzhen as monitoring object, this method was applied to implement structural safety monitoring of tower crane.The results show that monitoring data of each measuring point are in good agreement with the numerical analysis results.Tower crane in the use of the process is always in a safe state.

Key words: tower crane, structural safety, monitoring parameters, arrangement of measuring points, warning level
