Abstract
Stress relaxation behaviors of nonwoven geotextile and geomembrane which have protection, filtration and drainage, water barrier functions, respectively were analyzed. 'Theory of transition phenomena' was applied to interpretate the stress relaxation behaviors of two geosynthetics. The initial and later relaxation times for stress relaxation behaviors of geosynthetics were derived from the constitutive equations. The initial relaxation behaviors of these geosynthetics were dependent on the additional strains and were especially faster with temperature. Finally, both relaxation times of geosynthetics were shorter with additional strain and temperature.
보호, 여과 및 배수, 차수기능을 가진 부직포 지오텍스타일과 지오멤브레인의 응력완화거동을 각각 분석하였다. '전이현상 평형이론'이 이들 토목합성재료의 응력완화거동 해석에 적용되었다. 응력완화거동의 초기 및 후기완화시간을 구성방정식으로 부터 구하였다. 초기완화거동은 부가변형률에 좌우되며, 온도에 따라 빨라짐을 알 수 있었다. 끝으로, 이들 토목합성재료의 초기 및 후기완화시간은 부가변형률 및 온도에 따라 짧아졌다.
