This research will investigate the micro-structure of various types of non-woven geotextiles. Specifically 1) direct methods (water vapor impregnation and image processing techniques) will be utilized to quantify the micro-structures of the geotextiles of interest, in addition to the current practice of obtaining data only from indirect methods (dry and hydrodynamic sieving methods); 2) a number of performance tests will be conducted on various types of geotextiles and soils to evaluate the performance to determine the suitability of the geotextiles to a particular soil-type under simulated field conditions; 3) the micro-structure and the performance data received from step one and two respectively will, in turn, set the stage for the development of a mathematical model relating micro-structures of geotextiles and its hydraulic properties in field conditions; and 4) an attempt will be made to develop an expert system for selection of geotextiles for filter and drainage application.

本研究将探讨各种类型的非织造土工布的微观结构。具体来说，1)直接方法（水蒸气浸渍和图像处理技术）将用于量化感兴趣的土工布的微观结构，除了目前仅从间接方法（干式和水动力筛分方法）获得数据的做法；2)将对不同类型的土工布和土壤进行多项性能测试，以评估其性能，以确定土工布在模拟现场条件下对特定土壤类型的适用性；3)从第一步和第二步分别获得的微观结构和性能数据将为建立土工布微观结构及其在现场条件下的水力性能的数学模型奠定基础；4)尝试开发用于过滤和排水土工布选择的专家系统。
