Maintenance and Environmental Maintenance of Agricultural Water Supply Structuer, and giving of Durability Function

服部教授和绪方博士在鸟取县东部进行了碎片屏障体的劣化诊断。此外，还调查了鸟取县西部地震地震荷载作用下的农业村排水池中钢筋混凝土的附着情况。另一方面，研究了粉煤灰和熟料灰对各种混凝土强度的影响。此外，通过教学排水对混凝土的硫酸盐进行了检测。石黑博士构建了通过裂缝检测混凝土断裂特性的自动数据测量系统，并对添加了稻壳灰的混凝土的断裂特性进行了检测。此外，还考察了稻壳灰对碱集料反应控制和强度特性的影响。野中教授整理了农业给水构筑物的劣化机理和劣化诊断方法，并考察了修复和预防方法。此外，野中教授还提出了在农业供水设施的维护中引入特殊系统的建议。筱教授和松野博士研究了稻草灰作为混凝土掺合料使用的可能性。此外，还通过砂浆试件考察了稻草灰对强度等的影响。吉武教授和小林博士考察了受季风和台风影响严重的鹿儿岛县填海筑堤的地震灾害调查和对策。

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.
