地下工程的抗浮设计及措施介绍

The application and development of the anti-floating technology in underground engineering

随着我国城市化建设进程的进一步加快,城市地上空间和土地资源日益紧张。为确保城市更好更快的发展,对其地下空间的开发和利用迫在眉睫。但由于地下水的存在,使得地下工程易受浮力的不利影响。基于此,本文以地下结构的抗浮问题作为研究对象,探讨了抗浮技术的作用原理,介绍了抗浮设计及其施工技术,所得结果为地下工程抗浮技术的应用提供了基础。

With the rapid development of urbanization in China, the space and land of urban become scarce. The utilization of underground space of urban becomes more important to ensure the better and faster development of city. However, the development of underground engineering is restricted due to the presence of groundwater which causes the adverse effects of buoyancy. The anti-floating problem of underground structure is taken as the research topic in this paper and the principle of anti-floating technology is discussed.Furthermore, anti-float design and several anti-floating technical methods are introduced systematically. The obtained results would provide a basis for anti-floating technology in underground engineering.
