摘要
平原裂陷区内的基底构造运动所导致的地表垂直、水平形变,是通过大地测量进行定量描述的。本文根据华北平原裂陷区大地测量资料,结合区内典型地段断块沿断层运动的构造几何学特征,探讨盖层以下动态构造过程的地表形变效应;以垂直和水平两种形变资料为依据,配套研究基底构造的活动方式。这对平原裂陷区内利用大地测量探索浅、深层构造作用及其现今动态有实际意义。
The surface vertical and horizontal deformation caused from the besement structure movement in the plain fault trough area are described quantitatively by the geodetic measurement. In this paper, based on the geodetic measurement data in the North China plain fault trough, the surface deformation effect of the dynamic structure process under the overlying strata with the geometric characteristics of the structure of the fault block movement in the typical segment along the fault in the region hart been discussed. According to the vertical and horizontal deformation, the active way of the basement structure has been discussed too. It is significance for the inquirement of the effect of the lower and deep structure and recent dynamic state by geodetic measurement in plain fault trough area.
