基于块体理论的岩体稳定性实时分析系统研究

Real-time Analysis System of Rock Stability Based on the Block Theory

块体理论是岩体稳定性分析的常用方法之一。与其他数值分析方法不同,块体理论是几何分析,计算参数少而简单,计算过程快速,计算结果实用易懂。根据块体理论以上特征,结合信息技术等学科的最新发展,提出了基于块体理论的岩体稳定性实时分析与决策系统分析思想,首先从现场采集原始参数数据,并通过终端分析系统进行实时的计算和分析,同时原始数据与终端分析结果经通信系统传送到远程工作站进行同步计算和分析,并由相应专家组进行评估和决策,分析决策结果再实时反馈到现场,以确保工程岩体的安全和稳定。将块体理论分析方法与信息系统相结合,有利于块体理论的进一步推广和发展,对工程的安全施工和稳定运行有重要的指导作用,是物联网时代信息岩土工程发展的重要方向。

Block theory is one of the commonly used methods for rock stability analysis. Different from other numerical analysis methods, block theory is essentially geometrical analysis, which required little and simple parameters, the processing is rapid and the computing results are easy and practical. Based on the above characteristics of block theory, combined with the lately development of information technology, real-time analysis system of rock stability is proposed. Firstly, the original data can be collected from the field. Then the real-time computing and analysis can be conducted through the terminal system. And after that, the original data and the results from the terminal can be transported to the remote work station at the time of com- puting and analysis, based on which can be evaluated and the decision can be made instantly, so as to guarantee the safety and stability of engineering rock mass. This method combined block theory with information system, which is good to the promo- tion and development of block theory, and plays an important role in the safe construction and stable operation for a project. This is an important direction of information geotechnical engineering in the era of internet of things.
