In 2000, following major 3 topics were investigated. (1)Development of predicting technology for landslides due to up and down or water table in reservoirs, (2)Manufacturing of the medium size tri-axial compression test equipments which enable mechanical test under real/unsaturated soil condition of any earth structures, (3)Mechanical simulation getting much better estimation of the physical parameters in foundation using cracked model. In executing topic (1), the laboratory model test was used, which resembles the slope slide in circumference of a reservoir, and the detailed movement of a sliding mass was recorded and analyzed by stereoscopic camera, and they were analyzed by picture image processing techniques. While in executing the topic (2), the main efforts were devoted to manufacture the tri-axial cell which is able to measure pore water and vapor pressure independently. The developed apparatus is able to treat an unsaturated test sample of 15cm diameter, 30cm height.In 2001, TDR (time domain reflectmetry) instruments were introduced to measure the volumetric water content and this was applied to the topic (1). They gave some useful results. Also the AE (acoustic emission) measuring system was introduced, and it was used to investigate acoustic characteristics accompanied by failure of rock or concrete test samples.In 2002, the centrifugal loading apparatus was introduced to investigate the infiltration properties of chemicals into the re-cycled geo-materials (in this case, water plant sludge). And the results during the past 3-years of topics (1), (2) and (3) were abstracted.

2000年，研究了以下三个主要课题。（1）水库水位升降滑坡预测技术的开发;（2）中型三轴压缩试验设备的研制，使任何土工结构物都能在真实的/非饱和土条件下进行力学试验;（3）力学模拟，利用破裂模型更好地估计地基的物理参数。在课题（1）的实施中，采用室内模型试验，模拟水库周边的斜坡滑坡，用立体摄像机记录并分析了滑坡体的详细运动，并用图像处理技术进行了分析。在执行课题（2）时，主要致力于制造能够独立测量孔隙水和蒸汽压的三轴池。所开发的装置能够处理直径为15 cm、高度为30 cm的非饱和试样。2001年，TDR（时域反射仪）仪器被引入测量体积含水量，并将其应用于主题（1）。他们给出了一些有用的结果。此外，还引进了AE（声发射）测量系统，用于研究岩石或混凝土试样破坏时的声学特性。2002年，引进了离心加载装置，用于研究化学品在再循环土工材料（本例中为水厂污泥）中的渗透特性。并对课题（1）、（2）、（3）近3年的研究成果进行了总结。
