The surface subsidence in the Yellow River delta foreland area brings changes to the land surface height there, and the depth datum in the bathymetric survey is determined on the basis of the level of land bench mark, so the changes in the level of land bench mark will affect the determination of depth datum and the accuracy of bathymetric survey.

国家海洋局，第一海洋研究所，山东青岛 266061文章摘要：黄河三角洲前沿的陆地由于受地面沉降的影响，使地面高程不断发生变化。在水深测量中，深度基准面是根据陆地水准点高程确定的，陆地水准点高程的变化影响深度基准面的确定，从而影响水深测量的准确性。

The purpose of this thesis is to use finite element software ANSYS to analyze the mechanical behavior of thin-walled SUS304 stainless steel tubes with elliptic-notched subjected to curvature-controlled symmetric cyclic bending. The mechanical behavior contains the relationship among curvature, bending moment and ovalization. There are two kinds of the elliptic-notch.

One of the reasons for this is that the bearing capacity of the footing increases due to the increase of undrained shear strength with depth and the presence of a hard stratum within a finite depth.

引起这一不同的原因之一，是立足的承载力增加剪切强度的增加和深度、开挖的坚硬地层在有限的深度。

The first case is the variable depth with a fixed notch-width and the second case is variable width with a fixed notch-depth. It can be observed fromthe moment-curvature curve of the first case that the magnitude of the moment is larger for the deeper depth than that for the shallow depth.

由有限元素ANSYS 分析结果可以观察出，在控制固定曲度做循环弯曲负载时，弯矩－曲度曲线图显示出，在固定凹槽的宽度，当深度较浅时，达到设定的控制曲度所需施加的弯矩相对於凹槽深度较大的圆管要大的多。

The concrete dam displacement is studied considering the factors such as foundation modulus increasing with depth, seepage coefficient reducing as depth, seepage coefficient anisotropic, curtain and drainage in the dam heel and seepage field and stress field coupling. Some conclusions are obtained: if the foundation is considered only with the seepage volume load, the dam top horizontal displacement of the reference base point develops upstream. When the foundation size increases, the reference base point's horizontal displacement increases. However, the value measured by the reversed pendulum anchored to the rock foundation is often regarded to be absolute displacement. The above practice is estimated to be limited when the water load on the dam foundation is taken into account.

分析了地基变形模量随深度逐渐增加、渗透系数随深度逐渐减小、坝基渗透系数各向异性、坝踵设置帷幕排水，以及考虑渗流场和应力场耦合等对混凝土坝位移分量的影响，得出如下结论：作用在地基上的水荷载，使混凝土坝坝顶相对参考基点（倒垂锚固点或坝踵正下方1倍坝高处）的水平位移指向上游，而参考基点的水平位移随地基截取范围的增大而增大，由于大坝工程上常将倒垂线锚固在岩基深处，并认为该倒垂线测值为绝对位移。
