英文摘要Abstract Traditional laterally constrained inversion (LCI) can quickly and efficiently invert large geophysical data with minimizing the difference between adjacent model parameters. However when processing the data with large boundary differences, the inversion generates the result whoes the boundaries are poorly fitness with the actual underground geology. In order to overcome this problem, some specific measurement stations of original LCI has been adjusted to weaken the horizontal continuity constraint of the horizontal direction near the sharp boundary. The simulation results show that the determinations of station and weights value depend on the thickness or depth change at sharp boundary. In this paper, we employed single weighted laterally constrained inversion (SWLCI) method on the model with sharp boundary. The result showed that SWLCI can improve both the recovering of sharp boundary and the stability of inversion.
