摘要
西克尔水库2020年1月19日发生6.4级地震,对水库大坝及其他建筑物造成一定程度的破坏。坝体裂缝长度达1.6 km,裂缝最深深度达4.3 m。为保证水库日后安全运行,对震损后的水库进行除险加固设计,通过多种方案对比分析后,提出了挖除裂缝重新填筑碾压的裂缝处理措施、分层铺筑土工格栅的抗震措施、坝后增设排水和盖重的防液化措施,可为其他类似工程提供借鉴。
On January 19,2020,a magnitude 6.4 earthquake occurred in the Xiker Reservoir,which caused some damage to the dam and other structures of the reservoir.The length of the crack in the dam is 1.6 km,and the depth of the crack is 4.3 m.To ensure the safe operation of the reservoir,it is necessary to carry out hazard elimination and reinforcement design for the reservoir after earthquake damage.Through the comparison and analysis of various schemes,the crack treatment measure of excavating cracks,refilling and rolling,aseismic measures of laying geogrid layer by layer,anti-liquefaction measures of adding drainage and cover weight behind the dam are put forward.The design can provide reference for other similar projects.
