一、概述以土工织物代替砂砾石材料作滤层使用时,必须具备排水畅通和防止土颗粒流失的双重作用。因此,土工织物的孔径需根据被保护土颗粒的大小级配来确定。在海港工程中,作虑层使用的土工织物常采用无纺针刺涤纶丝织物。这种织物的特点是无经纬线之分,纤维排列方向无规律,抗拉强度 First, an overview to replace the use of geotextile sand and gravel material for the filter layer, you must have the dual functions of drainage and prevent the loss of soil particles. Therefore, the geotextile pore size should be based on the size of the protected soil grading to determine. In harbor engineering, geotextiles used as a floor layer often use non-woven acupuncture polyester silk fabrics. This fabric is characterized by no latitude and longitude of the points, the fibers arranged in an irregular direction, tensile strength
