原始应力状态 meaning in English
virgin state of stress
Examples
- This paper discussed about the changes of stress state on effect of soil properties . the reason of surface settlement and layer losses is that the stress state is not primeval one in and after tunneling construction . therefore it is necessary to select strength data in actual stress path in making tunnel deformation and stability analysis with continuous media mechanics
本文讨论了隧道施工过程中，由于应力状态的变化对土性的影响， ，隧道施工之所以造成地表沉降和地层损失，是因为隧道施工过程中以及隧道施工结束后土层的应力状态已经不是原始应力状态，因此在选用连续介质力学方法对隧道施工进行变形和稳定性分析时，必须采用实际应力路径下强度参数。
