古遗址边坡在卸荷条件下的稳定性研究

以铜绿山边坡为工程背景，分析了边坡的稳定性。采矿过程产生的卸荷力学条件与常规的加载力学试验参数、模型和方法完全不同。本文通过对卸荷岩体力学原理研究表明，对于采矿一类的岩体工程问题应该应用岩体卸荷的应力、应变路径来分析。本文从铜绿山遗址边坡的地质特征人手。在了解边坡地质特征的基础上，参照边坡的变形破坏现状，采用非线性弹塑性力学模型，运用ANSYS软件对古遗址边坡的采矿过程进行了分析。并且与不考虑采矿过程做了对比研究。

Study on the Stability of Site Slope under Loading and Unloading Conditions

In this paper, the slope stability of the rock slope is studied on the basis of Tonglushan slope project because the unloading mechanical condition in the process of mining is quite different from the conventional loading conditions--experimental parameters, models and methods. According to the geological features in Tonglushan site slope, this paper adopts nonlinear elastic mechanical models to analyze the mining process of the site slope with ANSYS software and makes a comparative research without considering the mining process.
