流动破坏 meaning in Chinese

flow failure

This mode of damage is essentially analyzed with a simple static approach by comparing post - earthquake residual strength of sand with initial stress due to gravity . the other involves limited , but often large , amount of deformation due to significant reduction in soil stiffness but without involving mechanism of failure in soil
一种为饱和砂土的强度的降低而导致的完全流动破坏；另一种为不涉及土体的破坏机理，但由于土体劲度的降低而产生有限的大变形，称为循环活动性。
