摘要

信息反馈施工方法在地下工程中被广泛地应用，但如何合理地应用监测数据仍是目前一个值得深入研究的问题。对地下工程施工监测数据提出了两种分析方法：一是在理论上讨论监测数据与洞周围岩性态的关系；二是对数据大小以及数据分布范围进行统计，通过分析得到洞周围岩变形规律。基于三维弹塑性损伤有限元方法，依据分析数据得到的信息，采用变尺度优化方法对地下工程进行反演分析，并对后续围岩变形进行合理地预测。通过对实际工程的分析，预测结果和监测数据变化规律基本一致，数值上吻合较好

因此为同类工程的信息反馈分析提供了一个有效地处理方法。

Abstract

Feedback analysis technology has been widely applied to underground engineering

and how to analyze the measured data efficiently is a hot topic to engineers. In this paper

two kinds of methods to study the data are discussed. One is to analyze the relationship between measured data and rock mass structures theoretically; the other is using statistics to get information of the numerical characters from measured data. According to the information got before

adopting variable metric method and FEM

the stability and deformation of the surrounding rock can be forecasted. Applying the methods mentioned above to the practical engineering

the predicted results preferably reflect the behavior of the surrounding rock’s deformation as going on of the power cavern excavation. Then an efficient method is provided for the design and construction of underground caverns.
