In the ground work for construction, it is very important to apply the sufficient preventive measures for the various accidents caused by groundwater. In practice, however, the groundwater surveys for planning these preventive measures have rarely been carried out with enough accuracy.
The authors have been trying to establish the method of groundwater survey for the above purpose and have published some useful techniques for this establishment. The most important problem at present is the interpretation of fluctuation characteristics of groundwater levels observed in construction sites. In the present study, we report this using the data of SKP building site.
