| Popis: | 84 The mechanical behavior of extensible geotextile reinforced retaining wall is studied in this research. A full-scale nonwoven geotextile reinforced retaining wall (1.2m × 1m × 1.5m in high × length × width) was built to monitor:(1) the vertical settlement and the maximum lateral deformation of the facing in each layer, (2) the distribution of tensile force in reinforcement, and (3) the development of failure surface in reinforced zone. Based on the experimental results, it is concluded that: (1) the Stage-Movable character of friction stress was proved by the full -scale test of nonwoven geotextile reinforced retaining wall,(2) the coefficient of lateral earth pressure near facing is approximately 0,(3) when the surcharge=0.8t/m2, the coefficient of later earth pressure is approximately the same as Ka in the top of the wall, but it is less than Ka in the bottom of the wall, (4) the shape of failure surface is bilinear which extend from toe to 2/3H in a constant slope, then it vertically extend to crest and the distance from facing to the bilinear failure surface is 0.4H. |
