摘要

在某大型地下洞室群工程的断面变形收敛监测过程中发现其时程曲线的波动程度有着明显的规律性，引入一维盒维数来定量描述该特征，在试算结果基础上探讨了其与围岩性质相关的力学含义。进而，通过采用该指标比较不同监测断面计算结果的差异，印证了盒维数与围岩完整性的对应关系。更进一步，分析各断面的空间位置及其盒维数值的关系，得出了整个区域内围岩完整性的演变规律。最终，由后继开挖过程揭露的围岩情况，证明整个推理过程和结论的有效性。

Abstract

During processing of section deformation’s convergent data of large underground cavern group engineering

obvious regularity is found at degree of fluctuation of the time history curve. Therefore

one-dimensional box dimension is introduced to quantitative description of this feature; and then relevant mechanical meaning of properties of surrounding rock is discussed based on the testing calculation results. Furthermore

the index is used to compare variation of the results of different monitoring cross-sections; and the corresponding relationship between integrity of rock and box dimension is confirmed. Through analyzing the relationship of various sections’ spatial locations and their box dimension values

the evolution tendency of rock’s integrity on the whole region is drawn. Finally

validity of the paper’s inference is proved by surrounding rock conditions which is revealed by subsequent excavation.
