覆土层 meaning in English
overbarden
overburden layer
Examples
- Influence on different overburden soils due to bedrock fracture
地下断裂对不同土质上覆土层的工程影响 - The test indicates that the response of shallow buried is larger than that of deep buried , which explain the importance of overburden to structures
试验表明浅埋情况的各种反应均大于深埋情况，这说明了约束结构的上覆土层的重要性。 - To know the rupture course and rupture range , we simulated the process of rupture on the overlaying soil with soft interlayer by plane strain finite element method in this paper
摘要为了了解软夹层对基岩上覆土层破裂的影响，确定土层的破裂范围，采用平面应变有限元法，模拟了有软夹层的上覆土层在断层错动时的破裂过程。 - Through shaking table test , in this paper the rule of the underground structure reaction to earthquake is summarized and the distortion of the structure and the mechanism of wreck are analyzed , especially the effect of overburden and the vertical earthquake to underground structure are studied
摘要文章通过振动台试验，总结了地下结构地震反应规律，分析地下结构的变形机制，并重点分析上覆土层和竖向荷载对地下结构动力性态的影响。 - Results show that the overlying soil with a soft interlayer can obstruct the rupture failure from bedrock up to the earth ' s surface , however , a soft interlayer which is deeply buried , will bring about a wider range of the earth ' s surface rupture failure ; in addition , the thickness of the soft interlayer may have effects on the rupture course of the overlying soil
从模拟的结果看出，软夹层对上覆土层破裂有一定的阻碍作用；当软弱层埋置较深时，一旦上覆土层破裂，失效土体的范围较大；软弱夹层的厚薄对上覆土层的破裂进程和破裂范围也有影响。
