项目摘要

This research project was enforced for the purpose of explaining the performance evaluation technique for the function diagnosis, control, preservation of the agriculture water supply facilities as an infrastructure stock. The result of this research is shown in the following.●The prediction of the neutralization and the examination of the diagnosis technique were done from a result of investigation with agriculture irrigation canal concrete passed in a long time service.●The evaluation technique of the scaling which is deterioration due to the freezing damage was examined, and a freezing damage diagnosis technique by the ultrasonic pulse method was examined.●The aging of mechanical characteristic of the irrigation pond body was examined by triaxial test the sample which the non-disturbance and density the same.●The physical and chemical character, the amount of element and strength of clay mineral, and permeability were examined by using the bottom mud of six different properties.●Ratio resistance electric investigation was carried out for the irrigation pond where improvement construction was being done with the leak due to decaying, and impervious property of the applicable body was evaluated by comparing the ratio resistance distribution of the improvement part and the un-improvement part.●The formulation background and the applicable condition of the estimating equation for the crack depth of concrete by ultrasonic pulse method were examined, and the conditional equation to decide the best installation position of oscillator and receiver was derived.●The LCC computation of the agriculture irrigation canal was examined by grasping the distribution conditions of the waterway network at one agriculture irrigation canal by GIS.

本研究项目的目的是解释农业供水设施作为基础设施的功能诊断、控制和保存的性能评估技术。本研究的结果如下。 ●根据长期使用的农业灌溉渠道混凝土的调查结果，进行了中和预测和诊断技术的检验。 ●对因冻害而劣化的结垢的评价技术进行了检验，并对超声波脉冲法的冻害诊断技术进行了检验。 ●混凝土机械特性的老化。采用三轴试验对无扰动、密度相同的样品进行检验。●采用六种不同性质的底泥，检验其理化性质、粘土矿物元素含量和强度、渗透性。●对因腐烂渗漏的正在整治的灌溉塘进行比电阻电调查，评价适用体的抗渗性能对比改进部分与未改进部分的比值阻力分布。●研究了超声脉冲法混凝土裂缝深度估算方程的制定背景和适用条件，推导了决定振荡器和接收器最佳安装位置的条件方程。 GIS 农业灌溉渠。
