是压溶构造的一种。碳酸盐岩中常见的一种裂缝构造。其成因有争论,但多数认为主要受上覆地层压力和温度作用而形成溶蚀。剖面上呈锯齿状的曲线;平面上呈现为参差不平、凹凸不平的面;立体上呈下凹与凸起大小不等的柱体。大小相差甚远,有的参差起伏十分明显,有的则较平坦以至逐渐与层面一致而消失。

It is discussed that there may be two reasons for the breakage of the samples:the pressure difference between the entering position and the outlet position and stress concentration of the sutures.
通过对试样破坏形态的观察推断出试样破坏可能的两方面的原因,其一为脉动流在流过试样时,管状试样承受的压力降有所差异,流体入口处的压力要大于出口处的压力;其二为缝合线处的应力集中。
