摘 要

近年来高层建筑施工迅猛发展，塔机作为主要的高层垂直运输机械广泛应用于主体工程施工中。由于塔机基础设计和安装拆卸专项施工涉及结构荷载取值、地基与基础、钢筋混凝土结构、钢结构、高耸结构、建筑机械、施工管理、设备检测、工程监理等诸多专业，技术含量较高，安装与拆卸过程较为复杂，发生安全事故的社会影响和经济后果严重。针对目前塔机安全问题，本文通过对塔机事故案例的原因分析，归纳出塔机安全事故的隐患问题及解决方法.

本文通过对以上问题进行论证分析和案例研究，归纳出课题的研究结论和建议。主要效益表现在：

1. 经济效益方面。避免塔机发生倒塌、折臂、坠物等群死群伤恶性事故发生。
2. 社会效益方面。维护了人民群众生命财产的安全，有利于家庭的幸福和社会的和谐。

ABSTRACT

In recent years recent years, by the rapid development of high-rise building construction, major high-rise tower is widely used in the main construction as vertical transport machinery. As the foundation design of tower crane and the installation and removal of special construction involves structural load value, groundwork and foundation, reinforced

concrete structure,steel structure, high-rise structures, construction machinery, construction management,equipment testing, project supervision, and many other professions, whose technical content is high, installation and removal process is more complex, and there will be seriously social

impact and economic consequences if security incidents happened. For the current security issues of tower crane, this paper analyzed the causes of tower crane accidents with some cases,and summarized the hidden problems and solutions of tower crane accidents.

Based on the analysis of the issues and case studies demonstrating above, the conclusions and recommendations of the subject researched are summarized. Through the

practice and empirical analysis by project supervision, the subject researched show its main benefits:

Firstly, the cost-effectiveness. To avoid the tower crane collapsed, folded arms, falling objects, etc. which will lead to serious injuries and deaths accidents.

Secondly, in the social effect. To avoid the tower crane accidents, safeguard people life and property safety, is conducive to family happiness and social harmony.
