查询词典 depth of field

Result After the ground-source heat pump system ran continuously for a period of time, the temperature field in the range with the semidiameter of 0.8 m around the underground pipeline showed intensive changes. The changes of the temperature field in the area outside this region became smaller till it was close to the original temperature of soil. The original temperature field in the soil of shallow ground surface showed an exponential correlation with the depth. When the depth reached to certain extent, the soil basically maintained the constant-temperature state and it was 1~2 ℃ higher than the annual average temperature.

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。

This paper presents a rapid inversion method for 3D apparent density based on separation and continuation of potential field. The new method is carried out in the following three steps. Firstly, the gravity field on the plane is separated by a cutting method into several parts corresponding to strata of different depth. Secondly, by the way of downward continuation, the field resulted from different strata is respectively reduced to a plane corresponding to its depth.
