| 摘要： | One of the most effective options to stabilize landslides is to reduce the amount of water they contain by installation of horizontal drains. A new type of horizontal drain material, geosynthetic wick drains, and a new installation method, that of driving drains rather than drilling them, has been evaluated. Horizontal wick drains offer several advantages over conventional horizontal drains: they resist clogging, they are inexpensive ($12/m installed), they may be deformed without rupture, and they may be installed by unskilled laborers with a minimal investment in equipment (typical rates exceed 5 m/hr). Since 1998, more than 100 drains totaling almost 1500m have been installed at eight sites in Missouri, Colorado, and Indiana using bulldozers, backhoes, and standard wick drain driving cranes. Significant drainage has been observed from the wicks, and reductions in the water table have been measured. |
