摘　　要：深基坑工程抗隆起安全稳定分析中涉及信息普遍具有随机性、模糊性、灰性及未确知性等不确定性。针对这一特性,文章应用盲数理论来表达分析参数的不确定性,提出了基于盲数运算法则的深基坑抗隆起安全系数计算新方法。实例研究表明,该模型为判断基坑的稳定状态提供了更全面的依据,克服了传统方法描述过于绝对化的问题,得到的结果更可靠。The information in the analysis of stability against upheaval of deep excavation is usually random,fuzzy,gray,and uncertain.In view of the uncertainty of the calculation parameters,the blind number theory is used to investigate a novel method to calculate the safety factors against the upheaval of deep excavation.The case studies show that compared with the traditional methods,the proposed method can judge the site condition better without absolutized description and the result is more detailed and reliable.
