摘要: 为推进岩土工程全过程的信息化,依据边坡工程、基坑工程、隧道工程的位移监测信息,将分形理论应用于岩体的稳定性分析。指出岩土变形是一个升维过程,且工程实例的分析结果表明位移时间序列的分维随着变形的发展将逐渐增加,无标度区也将越来越明显。利用分维的动态特征可以评价岩体对象的安全性,从而为实际工程的现场施工、反馈设计与后续运营提供参考。

关键词: 岩体稳定性, 分形理论, 位移监测, 位移时序

Abstract: To further informatize geotechnical engineering, fractal theory is adopted to analyze the stability of rock mass based on displacement monitoring data of slope engineering, excavation engineering and tunnel engineering. The results show that with the development of deformation in geotechnical materials, the fractal dimension of displacement time-series is increasing, and scale-free zone will become increasingly obvious. This phenomenon can be used for the evaluation of rock mass safety and offers references for construction, feedback design and operation of actual engineering.

Key words: stability of rock mass, fractal theory, displacement monitoring, displacement time series
