项目摘要

Prof. Hattori and Dr. Ogata carried out the deterioration diagnosis of the debris barrier body in the east part of Tottori Prefecture. Moreover, the adhesion of the reinforced concrete in the agricultural village drain tank that the seismic load of the Tottori west earthquake had been received was investitated. On the other hand, the influence of fly ash and clinker ash on various concrete strength was examined. And, a concrete sulfate was examined by the Teaching drainage water.Dr. Ishiguro constructed the automatic data measurement system to examine concrete fracture characteristics by the crack, and examined the fracture characteristics of the concrete mixing with rice husk ash. Moreover, the influence which rice husk ash exerted on the alkali-aggregate reaction control and the strength characteristic was examined.Prof. Nonaka arranged the deterioration mechanism and the deterioration diagnosis method of the agicultural water supply structure, and examined the repair and the reinforcentent method. Moreover, Prof. Nonaka was proposed to have to introduce a special system into the maintenance of agricultural water supply facilities.Prof. Shino and Dr. Matsunoto examined the use possibility of the rice straw ashes as the admixture for concrete. And, the influence which the rice straw ashes exerted on strength etc was examined by using the mortar specimen.Prof. Yoshitake and Dr. Kobayashi examined the earthquake disaster investigation and the countermeasure of the reclamation embankment in Kagoshima Prefecture which was inferior by the monsoon and the typhoon.

服部教授和绪方博士对鸟取县东部的碎片障体进行了恶化诊断。此外，还对鸟取县西部地震作用下的农村排水槽钢筋混凝土的附着力进行了研究。另一方面，研究了粉煤灰和熟料灰分对混凝土各种强度的影响。并用教学排水对混凝土硫酸盐进行了检测。Ishiguro构建了通过裂缝检测混凝土断裂特征的自动数据测量系统，并对稻壳灰混合混凝土的断裂特征进行了检测。此外，还考察了稻壳灰分对碱-骨料反应控制和强度特性的影响。野中整理了农业供水结构的劣化机理和劣化诊断方法，探讨了修复和加固方法。此外，有人建议野中教授在农业供水设施的维护中引入一种特殊的系统。Shino和Matsunoto博士研究了稻草灰烬作为混凝土掺合料的可能性。并通过砂浆试验考察了稻草灰对砂浆强度等性能的影响。吉竹和小林博士考察了受季风和台风影响较差的鹿儿岛县的地震灾害调查和围垦堤防对策。
