initial stress state

基本解释

The soil can be divided into different zones based on the variation of stress state compared with initial stress state.
相應於原始應力狀態變化情況可將其分爲幾個不同的區域。
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.
隧道按埋深分類應考慮的主要因素之一是圍巖的變形破壞方式，而後者與圍巖的初始應力狀態密切相關。
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.
由於隧道的形狀、巖性及其初始應力狀態的不同，結搆不同部位的動態響應有較大的差別，應分別評價其危險性。
