| 内容記述 | A lot of irrigation and drainage facilities along the Tone River downstream were damaged by the 2011 Tohoku earthquake. The National Institute for Rural Engineering (NIRE) surveyed the damage of the facilities from April to June after the earthquake occurrence for the purpose of grasping the general image of the damage and analyzing the cause of the failure. From the damage survey on the facilities due to liquefaction in Toride city, Kawachi town,Tone town, Inashiki city, Kamisu city in Ibaraki prefecture, Sakae town, Kozaki town, Katori city, in Chiba prefecture, the followings were summarized. 1） The heavy damage on the facilities caused by liquefaction was confirmed in Inashiki city in Ibaraki prefecture, Kozaki town in Chiba prefecture. 2） The type of observed damage to farmland and the agricultural facilities are classified into following categories. (1)Sand boiling, ground cracking in rice paddy by liquefaction, (2)Inflow of liquefied sands into drainage canals, (3)Uplift, inclination and fracture of drainage canals, (4)Relative gaps between the facility and ground with a pile foundation, (5)Water leakage of asbestos pipes. 3） Although water flow was failed due to inflow of liquefied sands into the drainage canals, it was observed that water flow was restored between one to two months after the earthquake. 4） The heavy damage of asbestos pipes was observed in Yotsuya site in Inashiki city. Damage rate of pipes in the extreme liquefaction-hazard area was 3.7 times in all the water distribution area. The rapid increase in damage rate ot pipes by liquefaction was suggested in the low earthquake resistance of asbestos pipes. 5） To improve the earthquake resistance of irrigation and drainage facilities, it is important to ensure the comprehensive approach to the earthquake-resistant taking into account the seismic risk and the importance of the facility. In this survey, it is found to cause serious damage to the facilities by liquefaction. The observed sites will be surveyed in detail and the countermeasure of earthquake resistant of each facilities will be discussed in future. |
