摘要

目前

地下工程围岩尤其是大型岩石地下工程围岩的粘弹塑性分析研究少见报道。针对这种情况

本文根据西原粘弹塑性流变模型相关理论开发了hhu-vp流变计算软件

以用于大型岩石地下工程围岩粘弹塑性流变数值模拟分析;并以一简单算例与软件FLAC-3D比较

结果偏差在容许范围内。将其应用于水布垭大型地下洞室围岩流变研究中

对该地下洞室的施工开挖及支护处理过程进行了模拟

提出了支护处理意见

并对其运营期的长期稳定性作出了评价。

Abstract

Right now

the reports about the visco-elasto-plastic analysis of surrounding rocks in underground projects

especially the large scale ones

have been little.Being aimed at this case

a rheological computational software named hhu-vp has been developed according to the theory of Japanese visco-elastic-plastic model in this paper.This software has been used to make a visco-elasto-plastic analysis of surrounding rocks in a large scale underground project.And a simple example was taken for the comparison of the results between the software hhu-vp and FLAC-3D

and the differences are within the limits of error tolerance. So the software has been applied to study the rheology of surrounding rocks of Shuibuya underground powerhouse.The excavating process and the supporting measures have been simulated to provide relevant suggestions.The long-term stability of surrounding rocks in the underground powerhouse in service has been evaluated as well.
