(一)前言针刺无纺士工织物,是以合成纤维为原料,用针刺方法将随意排列的纤维压制成的布状物。它的特点是耐腐蚀,抗拉强度高且各向几乎相等,透水性强及能防止被保护土的颗粒流失,具有滤层材料的基本特性,同时,在工程应用中具有工程量小、施工方便、工期短、费用低等优点,深受土木工程界的重视,为土石坝(包括水坝、灰坝、尾矿坝)、护岸及排水工程的滤层材料提供了新的途径,并在许多工程中得到应用,积累了
(A) Foreword Acupuncture non-woven workers fabric, is a synthetic fiber as raw material, acupuncture method will be randomly arranged fibers pressed into cloth. It is characterized by corrosion resistance, high tensile strength and almost equal to each direction, strong water permeability and can prevent the loss of particles of the protected earth, with the basic characteristics of the filter material, at the same time, engineering applications with a small amount of construction, construction Convenient, short construction period and low cost. It is highly regarded by civil engineering community and provides a new way for filter materials of earth-rockfill dam (including dam, ash dam, tailing dam), revetment and drainage project, Engineering has been applied, accumulated
