波兰学者A.萨武斯托维奇曾用弹性基础梁的方法给出能计算边缘鼓起的地表下沉剖面函数形式,但地表下沉盆地边缘并非总出现鼓起现象,有时实际鼓起量又小于萨氏公式中的计算鼓起量,因此其公式的应用受到一定限制;据此,探讨地表下沉盆地边缘由不鼓起到鼓起过程中移动与变形的关系具有一定实际意义。地表鼓起的原因尚未搞清,从一些实际资料分析,上覆岩层的岩性越硬,盆地边缘越易出现鼓起现象。笔者以萨氏公式为出发点,取地表最大下沉点为座标原点,按下沉
The Polish scholar A. Savovtovich used the method of elastic foundation girders to give a function that can calculate edge-domed surface subsidence profiles. However, the edge of the surface subsidence basin does not always have a bulge, and sometimes the actual bulge Which is less than the calculated bulge in the Sars formula, so the application of the formula is limited. Therefore, it is of practical significance to explore the relationship between the movement and the deformation in the process of bulging from the surface subsidence basin. The reasons for the surface bulging have not yet been clarified. According to some actual data, the lithology of overlying strata is harder, and the edge of the basin is more prone to bulge. The author of the formula for the starting point Saatchi, taking the maximum sinking point of the surface coordinates of the origin, according to sink
