制作与原岩结构面相似表面形态的模型试样是开展结构面力学模型试验的关键.基于不同尺度岩石结构面模型试样的制作特点,研制上、下盘完全吻合的系列尺度试样模具,并设计上、下盘吻合结构面试样的制作工艺,使得原岩结构面可以多次重复利用,提高原岩结构面的使用效率,降低取样成本和试验周期,实现在同一块结构面上不同尺度结构面模型的制作.利用表面形态相似性评价技术,验证制作工艺的可行性,结果表明,按照该逆向控制技术设计制作的模型试样,能复制出和原岩结构面表面形态一样、上、下盘结构面吻合度高的模型试样,符合制作不同尺度模型结构面的要求,可克服原岩结构面上下盘吻合度差、不能多种尺度取样的缺点,为开展具有真实表面形态的结构面抗剪强度尺寸效应试验研究提供了条件.

The key of structural plane model mechanical test is to make similar surface morphology model sample to the natural rock structural plane. Based on the making particularity of rock structural plane in different scales,sample modes in series scales with perfect match to upper wall and bottom wall were developed;and the making process of model sample was designed. Through this, the natural rock structural plane can be used repeatedly, which will increase the using efficiency, reduce the sample cost and trial cycle. What’s more, the different scales of structural plane model making on the same natural rock structural plane are achieved. In the second part of the work, the similar evaluation results of surface morphology show:the model sample made by inverse controlling technology is capable of duplicating the same surface morphology of rock structural plane and highly match between upper wall and bottom wall model samples, which is suitable for the demand of making model samples in different scales. The inverse controlling technology is able to overcome the problems of low match to upper wall and bottom wall model samples and unable to get samples in multiscale of natural rock structural plane, which provides conditions for experimental research on shear strength scale effect of real surface morphology rock structural plane.
