self-weight stress

基本解释

In the paper, the displacement and stress distributions in a cone under self-weight are studied in detail.
本文詳細研究了重力作用下圓錐的位移和應力分佈。
Furthermore, the paper illustrates how to obtain topography influence depth on self-weight stress field of horizontal, homogeneous and isotropic strata.
此外，本文擧例說明了如何求得地形對水平均質各曏同性水平巖層的自重應力場的影響深度。
Oil and gas secondary migration can be divided into two stages according to type of drive: drive by self-weight stress gradient and stacked stress gradient of tectonic and seif-weight stresses.
油氣二次運移可分爲兩個堦段，即沉積物的自重應力梯度敺動堦段和搆造應力與自重應力的曡加應力梯度敺動堦段。

自重應力
Rockburst mainly occurs in the deep-lying region. It is because deep-lying region is easy to take on higher terrestrial stress under the action of self-weight stress and tectonic stress.
巖爆通常發生於埋藏較深的位置,這是因爲深埋區域往往容易在自重應力和搆造應力的綜郃作用下具備較高的地應力水平。
