The masonry walls of Japanese castles are precious cultural properties, and many people come to sightseeing on the castles. For this reason, in the conservation of their careful consideration is required both preservation of their cultural properties and stability of foundation structure of them is required. From recent studies, it was gradually discovered that Japanese traditional masonry walls are stable for both static and dynamic conditions. For preservation and restoration of them, the appropriate evaluations and measures based on examination of the geotechnical engineering are needed.

A geologic profile expresses the geological feature situation in its location clearly and makes the problem on the geological feature clear. It has to be made by considering the topography condition of the place that the stratum was accumulated, sedimentary environment and the sedimentary age. A study of an Alluvium deposit substantially develops from three sides: a decision in a sedimentary age, presumption of sedimentary environment and introduction of a sedimentary facies analysis in recent years. A geologic profile has to be made so that formative process of the ground may be indicated based on recent research achievements about an Alluvium deposit.

In this paper, four case studies are reported in which the embankments of highway made on sloping ground have failed after completion of the road construction works. Relationship between the rainfall and the groundwater was presumed to be the main cause of such failures. Furthermore, some important points aimed at the maintenance, such as the inspection and the reinforcement of slopes, are discussed in this paper.

Recently SAR images have been widely adopted for the monitoring of ground surface deformation. InSAR (interferometry SAR) becomes a powerful tool to clarify geological structures and tectonic motions cause of large earthquakes. The InSAR analysis which is centimeters order precision and used two images is convenient to make a quick report for the surface deformation after large earthquakes. On the other hand, PSInSAR technique which uses 20 SAR images or more over realizes millimetric precision in a wide area with a high-density. Especially, it enables to detect the historical deformation of the surface according to used images term. This paper discusses the geological structure and the mechanism of surface deformation for the Noto Hanto Earthquake in 2007 and Mid Niigata prefecture Earthquake in 2004.

Kansai international airport was constructed on reclaimed island 5 km offshore. Water depth around the island is deep and its reclamation layers are very thick. Therefore consolidation settlement had expected not only alluvial clay layers but also diluvial clay layers. Prediction of settlement is necessary to construction and maintenance of Kansai international airport. Important points to solve the problem are as shown below: (1) Construction of geological database, (2) Management of reclamation load step, and (3) Monitoring and analysis of settlement data. This report describes our concept that adopted development and application of geological data base system to these points.
