依托印尼雅万高铁全线最高墩、最大跨度T型刚构DK887大桥项目,介绍万隆方向桥台基础防护补强的施工方法及措施,对高陡边坡稳定性进行检算,结合现场地形和地质情况,采用预应力锚索墩+锚索格梁的加固措施,经验收试验检测,证明设计合理,现场施工、质量、安全可控,后期变形监测满足设计和规范要求.
In relation to the project of the highest pier in the whole line,the largest span T-type rigid frame DK887 Bridge of Jakarta—Bandung High-speed Railway in Indonesia,it introduces the construction methods and measures of protection and reinforcement of abutment foundation in Bandung direction.The stability of the high slope was checked,combining with the actual topography and geological condition of the slope,the reinforcement measures of prestressed anchor cable pier and anchor cable lattice beam were adopted.Through the acceptance test detection,the rationality of the design is verified.the construction on the site,quality and safety are controlled at the same time.The later deformation monitoring meets the design and specification requirements.
