It's this weak layer that's at the root of most avalanches. The bonds between the large cup-shaped snow crystals in this layer are only weak and they break easily.
这种疏松层便是大多数雪崩形成的根源，该层中大的杯状雪晶之间的键合很弱，非常容易断裂。
The main disease of the dike include: Seepage, crack, slip, cave, weak layer, collapse, pipe breach.
堤坝的主要病害有：渗漏、裂缝、滑坡、孔洞、软弱层、坍塌崩岸、涵管破裂。
And if such a weak layer sits in the middle of the snow pack, it becomes an avalanche waiting to happen.
如果这种疏松层位于积雪的中部，雪崩便很容易被触发。
The engineering properties of the weak layer are controlled by the basic substance and environment conditions.
软弱层带的工程特性是其物质基础与环境条件共同作用的结果。
It is also found that the strength is controlled by a certain relationship between the shear wave velocity and the thickness of the weak layer.
研究还发现，这种放大作用的强度受软弱层波速与厚度之间的某种关系制约。
Together with engineering case, this paper introduces this technique application to make known karst, fault zone and intensive weathered bed weak layer.
文章结合工程实例，介绍利用地震层析成像技术查明岩溶、断层破碎带、强风化软弱夹层方面的应用。
In this paper, through mathematically imitating the slightly inclined weak layer consolidated with shear keys in the gravity dam foundation, the failure mechanism of shear keys is studied.
本文采用有限单元法，对加固重力坝基础缓倾角软弱结构面抗滑硐塞系统的破坏机理进行了初步分析。
The crack will deflect because the weak layer exits, which will absorb more amounts of fracture work and improve the crack tolerance greatly, therefore the fracture toughness increases remarkably.
这是由于弱间层的存在将出现裂纹偏转现象，吸收大量的断裂功，从而大幅度提高了裂纹的扩展容限，使断裂韧性有较大增长。
