摘要:

深圳地铁一号线国大段下穿百货广场大楼,遇到18 900kN的桩基托换,如此大吨位的桩基托换在国内外尚属首例,因此设计、施工均存在很大风险.首先介绍风险分析理论,并在此基础上进行国大段特大轴力桩基托换的风险分析。

Abstract:

 Underpinning to pile foundation of 18900kN pressure which has not been met in and out of China before, happened to the building of General Merchandise Between Guomao Station and Dajuyuan Station on line 1 of Shenzhen metro. Based on the theory of risk management, the risk of underpinning to the pile foundation is presented in this paper.

Key words:  , risk analysis  , risk management  , underpinning to pile foundation
