The influence of size effect on the hydromechanical behavior of rock mass has long been recognized. As a result, analysis of the rock mass size effect has been developed. However, when conducting size effect studies, the representativeness of the sample is less considered. Therefore, combining the existing statistical methods and sampling methods, a comprehensive representative sampling method for rock mass is present. In this method, a large number of sample statistics of different sizes are provided in the progressive coverage method; then, the plane density of the track length is defined as the value of stratification to perform stratified sampling for representative samples. Furthermore, it is applied to a joint network model generated in accordance with the actual situation and compared with those of other methods. The sampling results show that the proposed method can provide a certain reference value for studying the scale-dependent behavior of rock mass mechanical parameters.

节理岩体尺寸效应试验的代表性采样方法

尺寸效应对岩体流体力学行为的影响早已被认识到。因此,已经开发了岩体尺寸效应的分析。然而,在进行规模效应研究时,较少考虑样本的代表性。因此,结合现有的统计方法和采样方法,提出了一种综合的具有代表性的岩体采样方法。在该方法中,渐进覆盖法提供了大量不同大小的样本统计量;然后,将轨道长度的平面密度定义为分层值,对代表性样本进行分层抽样。此外,将其应用于根据实际情况生成的联合网络模型,并与其他方法进行比较。
