Dynamic Shear Properties of Geosynthetics Interfaces Relevant to Earthquake Hazard Mitigation

土工合成材料在岩土工程中的应用 在过去十年中，这种做法大大增加。 今天， 土工合成材料用于过滤，排水， 分离，土壤加固，渗流控制，在许多 其他应用。 本研究项目的主要目的是评估 不同土工合成材料土界面动态剪切特性 系统. 目标是获得所需的基本信息， 土工合成材料-土壤系统的行为和性能， 通过应用在减轻地震灾害，如：基地 隔离地震地面震动，土边坡加固 用土工布和土工格栅，以及土工膜内衬的运河， 水库、隧道和危险废物填埋场。 还注意到需要进行研究， 开发了一种可靠的动态接口测试程序 特性.

The use of geosynthetic materials in geotechnical engineering practice has increased greatly during the past decade. Today, geosynthetic materials are used for filtration, drainage, separation, soil reinforcement, seepage control, and in many other applications. The primary objective of this research program is to evaluate the dynamic interface shear properties of different geosynthetic soil systems. The goals is to obtain needed information on the basic behavior and performance of geosynthetic-soil systems, motivated by applications in earthquake hazard mitigation, such as: base isolation from earthquake ground shaking, earth slopes reinforced with geotextiles and geogrids, and geomembrane lined canals, reservoirs, tunnels and hazardous waste containment landfills. Attention is also addressed to the need for research and development of a reliable testing procedure for dynamic interface properties.
