本文针对谷坡地形,考虑其影响,提出了反演河谷山坡地形形成过程来确定地应力场的近似方法,并进一步分析了谷坡地形地下洞室围岩应力应变的特点。
In this paper, aiming at the valley slope topography and considering its influence, an approximate method to retrieve the geostress field of valley hill slope topography is proposed to determine the geostress field. The stress and strain characteristics of surrounding rock in underground valley of valley slope are analyzed.
