抄録

The effects of drainage well work, a construction method used to prevent landslides, were studied and the following results obtained.<BR>(1) To understand the groundwater drainage effects of installing a drainage well on a sloping slide area, it is necessary to study the drainage caused by the drainage boring in addition to the drainage caused by the drainage well itself.<BR>(2) The study confirmed that after installing a drainage well, the groundwater level is low close to the drainage well but rises as the distance from the drainage well increases.<BR>(3) The overall decline in the ground water level accompanying the construction of the drainage well can be found using formula (1).<BR>(4) The decline in the ground water level accompanying the construction of the drainage well is limited to the area where drainage boring has been performed.
