覆盖于斜坡120d的黄麻土工布重量降低6%~7%,覆盖250d左右降低20%~40%。在人工模拟大雨强条件下,使用126d的黄麻土工布比光板地推迟3min产流;中雨强时,使用227d和480d的黄麻土工布比光板地分别推迟4.95,0.57min产流。使用124d的黄麻土工布控制侵蚀效应非常显著,可比光板地减少径流量87.45%,减少产沙量99.88%。使用298~323d的黄麻土工布比光板地减少径流量63.24%~66.19%,减少产沙量97.32%~97.39%。使用340~480d的黄麻土工布减水减沙能力有明显降低,但在降雨量为9.2~163.8mm的范围内,仍能减少径流量25.4%~49.79%,减少产沙量70.99%~87.66%。
The weight of jute geotextile covering the slope 120d is reduced by 6% ~ 7%, and the coverage is reduced by 20% ~ 40% after about 250 days. Under the condition of artificial simulated heavy rain, the jute geotextile with 126d was delayed for 3min by using the geotextile. When the rain was strong, the jute geotextiles with 227d and 480d were postponed for 4.95 and 0.57min respectively. The use of 124d jute geotextile control erosion effect is very significant, than the light board to reduce runoff 87.45%, reduce sediment yield 99.88%. Using 298 ~ 323d jute geotextile light to reduce the runoff 63.24% ~ 66.19%, reducing sediment yield 97.32% ~ 97.39%. The use of jute geotextiles with 340 ~ 480d reduced water and sediment capacity significantly reduced, but in the range of 9.2 ~ 163.8mm rainfall can still reduce runoff 25.4% ~ 49.79%, reduce production The amount of sand 70.99% ~ 87.66%.
