9512434 Gosink Geomechanical problems are characterized by large amounts of data, significant variability, and lack of experimental control. Analysis is frequently dependent upon remote sensing of various types, including geotomography, and acoustic and microwave methods. Computationally intensive models, discrete element methods, and inversion techniques, are employed to determine soil and rock properties, and their response to civil works, contaminant dispersion and seismic loading. At CSM, investigators have been actively involved in both experimental and computational studies of geomaterials; these studies now require enhanced computational capability and instrumentation for continued success. The research strategy advances a systems approach to the analysis of geomaterials. Rather than focusing on computation without data acquisition or the reverse, we are proposing a suite of computers and instruments which, working together, can substantially increase our understanding of fundamental properties and processes in soils and soil/rock mixtures, as well as in other material applications. This information has relevance to problems of the civil infrastructure, contaminant transport and fate in soils, construction issues, design for seismic considerations, transportation technologies, energy technologies and pollution minimization and waste management. ***

9512434 Gosink 地质力学问题的特点是数据量大、变异性大且缺乏实验控制。 分析常常依赖于各种类型的遥感，包括地层摄影、声学和微波方法。 采用计算密集型模型、离散元方法和反演技术来确定土壤和岩石特性及其对土木工程、污染物扩散和地震载荷的响应。 在 CSM，研究人员一直积极参与岩土材料的实验和计算研究；这些研究现在需要增强计算能力和仪器才能持续取得成功。 该研究策略推进了岩土材料分析的系统方法。 我们提出的不是专注于没有数据采集的计算或相反的计算，而是提出一套计算机和仪器，它们一起工作可以大大增加我们对土壤和土壤/岩石混合物以及其他材料的基本属性和过程的理解应用程序。 这些信息与民用基础设施、污染物迁移和土壤归宿、建筑问题、抗震设计、运输技术、能源技术以及污染最小化和废物管理等问题相关。 ***
