求取滑坡体积在当前是一个难题,原因是其为三维分量,并且部分滑面往往在地下。本文提出了3个区域地震滑坡体积优化模型来计算2008年中国汶川M W7.9地震触发滑坡的体积。本文首先基于20m分辨率的震前和震后SPOT 5卫星影像提取到的数字高程模型(DEM)数据,结合少数滑坡的剖面图,获得了1 415处汶川地震滑坡堆积区体积,作为地震滑坡体积模型训练样本。在常规区域滑坡"体积—面积"模型基础上,提出了3个优化模型。分别利用数据的对数化线性拟合与直接非线性拟合方法对1个常规模型和3个优化模型进行拟合。结果表明,采用直接非线性拟合方法并考虑了滑坡长、宽、高、岩性、坡度和峰值地动加速度后,坡向的优化模型标准误差最小,回归得到的滑坡总体积与滑坡真实总体积也非常接近。将这一模型应用于所有汶川地震滑坡,分别得到每个滑坡的体积。最终结果表明,汶川地震滑坡相对密集分布区内的196 007处滑坡的堆积物体积约为1.2×1010 m^3,源区体积约为1×1010 m^3。根据前人"地震震级—滑坡总体积"经验公式得到的结果仅仅是本文结果的7.5%~9%,这提醒我们有必要基于更多的单次地震触发滑坡总体体积数据对"地震震级—滑坡总体积"的关系进行更新。同时,文中的优化模型对同类研究也有显著的参考价值。

In order to find the intrinsic physical mechanism of the original Kármán vortex wavily distorted across the span due to the introduction of three-dimensional (3-D) geometric disturbances,a flow past a peak-perforated conic shroud is numerically simulated at a Reynolds number of *** on previous work by Meiburg and Lasheras (1988),the streamwise and vertical interactions with spanwise vortices are introduced and *** vortex-shedding patterns in the near wake for different flow regimes are reinspected and illustrated from the view of these two ***,in regime Ⅰ,spanwise vortices are a little distorted due to the weak *** in regime Ⅱ,spanwise vortices,even though curved obviously,are still shed synchronously with moderate streamwise and vertical *** in regime Ⅲ,violently wavy spanwise vortices in some vortex-shedding patterns,typically an Ω-type vortex,are mainly attributed to the strong vertical interactions,while other cases,such as multiple vortex-shedding patterns in sub-regime Ⅲ-D,are resulted from complex streamwise and vertical interactions.A special phenomenon,spacial distribution of streamwise and vertical components of vorticity with specific signs in the near wake,is analyzed based on two models of streamwise and vertical vortices in explaining physical reasons of top and bottom shear layers wavily varied across the *** these two models and above two interactions are *** two sign laws are summarized:the first sign law for streamwise and vertical components of vorticity is positive in the upper shear layer,but negative in the lower shear layer,while the second sign law for three vorticity components is always negative in the wake.
