The primary objective of this work is to improve our understanding of the scale effect of the joint shear behavior. Attempts are made to combine different proposed methods with the multiscale joint shear test. First, a new type of rock-like material made from a mixture of raw materials is used to simulate rock joints. Then a new sampling method is used with the progressive coverage statistical method for the representative sampling of actual joints, and an inverse controlling technology is designed with an invented series of multiscale molds for the construction of a similar surface model in series scale (100 mm × 100 mm to 1000 mm × 1000 mm). Finally, the independently developed multiscale direct shear tester is used to measure the shear behavior of joint replicas. The quality of results shows the capacity of this experimental technology in investigating the scale effect of the joint shear behavior.

串联尺度岩石节理模型抗剪强度试验技术

这项工作的主要目的是提高我们对关节剪切行为的尺度效应的理解。尝试将不同的建议方法与多尺度接头剪切试验结合起来。首先，使用一种由原材料混合制成的新型类岩石材料来模拟岩石节理。然后采用新的采样方法和渐进覆盖统计方法对实际节点进行代表性采样，并设计了逆向控制技术，设计了一系列多尺度模具，用于构建系列尺度（100 mm × 100 毫米至 1000 毫米 × 1000 毫米）。最后，采用自主研发的多尺度直剪试验机测量接缝复制品的剪切行为。
