中国地质灾害种类多、分布广、危害大,是世界上地质灾害最严重的国家之一。若单纯依靠地面调查,周期长、费用高,且难以完整覆盖。近年中国航天技术和遥感技术的飞速发展为地质灾害的调查和研究提供了崭新的手段。利用高分辨率的国产遥感数据进行灾体和承灾体解译,不仅易于识别、覆盖全面,明显的提高成果质量,而且还能缩短时间,节省资金,极大地提高工作效率,起到事半功倍的作用。笔者利用中国地质环境监测院开发的"基于国产卫星的地质灾害调查监测系统",选择陕西宝鸡黄土区为实验区,在"地质灾害遥感调查系统"平台上开展国产遥感数据处理、地质灾害体信息解译和灾害体易发评价等工作。结果表明"基于国产卫星的地质灾害调查系统"有效实现了海量遥感影像数据的处理、成果的管理和输入输出,而开发的自动信息提取及模型化的危险性评估在取得良好结果的同时大大节省了人力物力成本,这为该系统今后的应用和推广奠定了基础。

为模拟边坡在库水涨落和降雨作用下的渐进破坏过程,发展基于连续介质离散元的双重介质渗流应力耦合模型。它分为固体计算模型、孔隙渗流应力耦合模型和裂隙渗流应力耦合模型3个部分。固体计算模型能够反映地质体的破坏规律,可以模拟从连续到非连续的破坏过程;孔隙渗流应力耦合模型可以方便地计算出自由水位线(浸润线)的位置;裂隙渗流应力耦合模型可以避免由于不连通裂隙(孤立裂隙)存在所导致的收敛性问题;假设只考虑库水涨落和降雨的最终状态,裂隙渗流产生的水头分布和由库水涨落所引起的水头改变作为孔隙渗流的变边界条件,从而实现孔隙渗流场和裂隙渗流场的耦合。典型算例计算结果表明,基于连续介质离散元的双重介质渗流应力耦合模型对于库区古滑坡的研究是很有效的。

Based on the Latin square design of statistics, the thickness of first boundary layer, the turbulence model and the cell number were taken as the three main factors of uncertainty in CFD （computational fluid dynamics）. Total resistance of hull was calculated and the flow field around the hull was simulated by CFD method. Then, the influence of uncertainty factors on the hull resistance was discussed by regression analysis with trimmed mesh and overset mesh. Through a series of calculation and analysis, the optimal calculation method was put forward, and the relevant parameters of the calculation were determined. Thirdly, the total resistance of different speed was calculated by using these two kinds of grids, which were in good agreement with the experimental results. Finally, according to the ITTC recommended procedures, uncertainty analysis in CFD was carried out with the numerical results of the total resistance by three sets of grids with uniform refinement ratio rG = √2. Then the modified resistance was compared with the experimental result, which improved the accuracy of the resistance prediction.

关键词： Resistance prediction Latin square design regression analysis trimmed mesh overset mesh.
