项目摘要

1) Location, damage and emergency repair of embankment dams damaged by the 1995 Hyogoen-nanbu Earthquake are unified in a GIS database.2) The following in-situ tests were performed to evaluajte earthquake resistance of restored embankments and foundations at the embankment dams of Niroku-ike, Sugatadani-ike and Daiteibou-ike damaged ; boring log, PS loging, Reflection logging.3) Stability analysis during earthquake and earthquake response analysis were performed to consider the main cause of the damage for the embankment dams of Idenoshiri-ike and Niroku-ike, and it is concluded that the main cause is the development of excess pore pressure in the upper slope of these dams.4) Cyclic undrained triaxial tests under strain-path control were performed using embankment materials sampled at the three embankment dams mentioned above. The purpose of this test is to consider the possibility of simulating soil strain behavior during earthquake usirtg test results. Control and data acquisition programs are developed for this test using Visual Basic. As a result of the test, it is concluded that the control of strain amplitude is easier than the conventional test under stress-path control, and that the deformation characteristics of shear modulus ratio and damping ratio.5) K0 consolidation test is easily controlled using strain-path control.6) The dynamic deformation analysis of two-dimensional model of embankment dams was proposed to evaluate earthquake resistance of embankment dams using dynamic deformation parameters obtained form the cyclic tests.7) Color figures of the analyzed results were shown to be available for design using KSUWAD.

1）在GIS数据库中统一了1995年hoogoen-Nanbu地震破坏的路堤大坝的损坏和紧急修复。2）2）进行以下原位测试，以评估恢复的堤防和基础的耐修复堤的耐药性，并在Niroku-sike-sike，sugatadadadani-ike和Daimibou的堤坝上进行地震; 3）进行地震和地震反应分析期间的稳定性分析，以考虑Idenoshiri-ake和Niroku-sike的路堤大坝损坏的主要原因，并且可以得出结论，主要原因是，在这些水坝的上限下进行了过量的孔径，其孔隙压力是在这些水坝上进行的孔隙压力。在上面提到的三个路堤大坝上取样。该测试的目的是考虑在地震USIRTG测试结果中模拟土壤应变行为的可能性。使用Visual Basic开发了该测试的控制和数据采集程序。 As a result of the test, it is concluded that the control of strain amplitude is easier than the conventional test under stress-path control, and that the deformation characteristics of shear modulus ratio and damping ratio.5) K0 consolidation test is easily controlled using strain-path control.6) The dynamic deformation analysis of two-dimensional model of embankment dams was proposed to evaluate earthquake resistance of embankment dams using dynamic形成循环测试的变形参数。7）被分析结果的颜色数字可用于使用Ksuwad进行设计。
