一、前言 作为土木工程、水利水电水运工程建设的新材料,无纺土工织物的应用要比有纺土工织物的应用更为广泛。研究无纺土工织物与土体或其它建筑材料接触后的孔眼变化及其透水性、保砂性有其现实意义。这些问题将涉及到织物排水、滤层设计和实际工程效果。 I. INTRODUCTION As a new material for civil engineering, water conservancy, hydropower, and water transportation engineering, the application of non-woven geotextiles is more extensive than that of geotextiles. It is of practical significance to study the change of pores and the water permeability and sand retention of non-woven geotextiles after contact with soil or other building materials. These issues will involve fabric drainage, filter design, and actual engineering results.
