搞岩石的朋友可以看一下:带三组软弱面的本构模型

最近和师弟讨论带节理的岩体如何分析,无意中想起了ZSOIL3D中的Multilaminate model。
现和大家共享,看看是否对做岩体工程的朋友有帮助。

这是参数。
母体岩石可以有MC,HW本构选择。

这是一个工程实例:

ABSTRACT: A decision of the authorities of the canton of Jura in Switzerland to investigate the possibility of rehabilitating the caves of the former lime mines of Saint Ursanne as a convention and concert hall required a complete safety reassessment of the caves which is described in this paper. The age of the caves indicates that overall stability is not questionable; local instabilities are however identifiable on inspection. These local instabilities are related to weakness planes in the rock structure and indicate that chunks of rock could be mobilized in local failure mechanisms. A safety assessment study was conducted by visual inspection and numerical simulation with finite element code Z_Soil.PC, comparing results obtained using different modeling and constitutive assumptions. These analyses allowed us to identify the influence of different rock characteristics and the most critical  failure mechanisms; precise rehabilitation measures could be proposed to the site owner. This paper illustrates the role that elastoplastic numerical simulations can play in a reliable safety evaluation of natural caves.

我现在也在做岩体本构方面

我们这里有做岩石流变的,呵呵。
