摘要

Permeable pavement and infiltration trench are presently considered to be more effective countermeasures for controlling storm-water runoff on the roads. Being a continuing research on the infiltration trenches, this study verified the variation of infiltration capability of trench with time by performing three sprinkling experiments in three consecutive years on a trench constructed in a real highway. From the experimental results, it was presumed that clogging occurred in the trench during the progress, and that infiltration from the trench had no marked impact on the surrounding earth structure. In addition, based on an analysis of the variation of water depth under the real rainfall observed in July 2005, it was also found that this trench could perform effectively for controlling the storm-water runoff, even after a torrential storm.
