Investigation of the Remains of a Boiler House in Maizuru 3RD Naval Explosives Arsenal
AIJ Journal of Technology and Design
We carried out excavation of the remains of a boiler house in Maizuru 3rd Naval Explosives Arsenal. This investigation consists of measurement of the remains, performance evaluation of concrete, and estimating construction method. As a result, it was estimated that the boiler house was consisted of reinforced concrete foundations/walls, plain concrete floor, and some members from plain or fire bricks. On the other hand, the performance of concrete used for the remains was standard compared with the technical standards during World War II. These results will contribute to the grasp and the evaluation of the then architectural technology and design.
BULLETIN OF THE GEOLOGICAL SURVEY OF JAPAN, 2003
The geology of the Yatsuhashi area in Shitara Town, Aichi Prefecture has been investigated to draw the distribution of clastic sediments of the Lower Miocene Hokusetsu Subgroup (lower part of the Shitara Group). A 5.5 km x 4 km area has been mapped in detail. The clastic sediments are lithologically divided into four formations: from base to top, the Taguchi Formation (dominantly coarse-grained clastics such as ill-sorted breccia and conglomerate), the Kawakado Formation (dominantly sandstone), the Ohno Formation (dominantly mudstone), and the Kadoya Formation (felsic tuff and tuffaceous clastics). An overall upward-fining sequence characterizes this subgroup. The coarse clastics of the Taguchi Formation are mostly fluvial and debris-flow deposits and in minor amounts are probably of talus origin. These clastics fill past-valleys incised into pre-Tertiary basement, resulting in an irregular distribution. On the other hand, the other formations are made of wellbedded marine sediments, the distribution being not complex. The Hokusetsu Subgroup is covered unconformably by volcanic rocks of the Middle Miocene Nansetsu Subgroup (upper part of the Shitara Group). In the eastern part of the mapped area, intermediate to mafic volcanic intrusions form a north-south striking dike swarm.
