土工织物是一种新的工程材料,它正式应用于土建领域,在国外始于1958年,在国内则起步不久,处在试验研究阶段。但由于它比传统材料具有许多独特之处,因而应用前景广阔。1986年在坳上水库上坝排水体中,采用土工织物代替砂、卵石作滤层进行试验,经过一段时间的运用,证明土工织物滤层效果良好。 Geotextile is a new engineering material, which is formally used in the field of civil engineering. It started in 1958 in foreign countries, but started in China soon after. It is in the stage of experimental research. However, because of its many unique features than traditional materials, the application prospect is promising. In 1986, on the drainage dam of Au Upper Reservoir, geotextiles were used instead of sand and pebbles as the filter layer. After a period of application, the effect of the geotextile filter layer was proved to be good.
