initial stress state

The soil can be divided into different zones based on the variation of stress state compared with initial stress state.

相应于原始应力状态变化情况可将其分为几个不同的区域。

One of the important factors taken into account in the tunnel classification is the style of deformation and failure, which is related to initial stress state in wall rock.

隧道按埋深分类应考虑的主要因素之一是围岩的变形破坏方式，而后者与围岩的初始应力状态密切相关。

Because the structural response differs with differing tunnel shape, wall rock properties, and initial stress state, the safety of the tunnel in different location should be estimated respectively.

由于隧道的形状、岩性及其初始应力状态的不同，结构不同部位的动态响应有较大的差别，应分别评价其危险性。
