作为两类典型的沉积盆地,伸展盆地和前陆盆地的沉降定量分析模型及模拟技术,近年来不但取得了长足的进展,而且已被广泛应用.本文着重介绍了如下几方面问题:(1)回剥法求取盆地沉降;(2)双层剪切模型求取伸展盆地沉降;(3)弹性板挠曲模型求取前陆盆地沉降;(4)通过实例分析,探讨了应用正演理论模型与反演回剥法结合技术,进行盆地沉降模拟的基本方法.通过对这些问题的研究,可以揭示这两类典型沉积盆地的成因和沉降机制,进而为盆地地球动力学分析提供一种重要的研究方法.
As two typical sedimentary basin, extension and foreland basin settlement quantitative analysis model and simulation technology, not only made considerable progress in recent years, but also has been widely used.This paper focuses on the following aspects: (1) Back-stripping method to obtain basin settlement; (2) double-layer shear model to obtain extension basin settlement; (3) elastic plate deflection model to obtain foreland basin settlement; (4) through case studies, Model and the back-stripping method combined with the basic method of basin subsidence simulation.By studying these problems, we can reveal the genesis and sedimentation mechanism of these two typical sedimentary basins, and then provide an important for the geodynamics analysis of the basin Research methods.
