摘要
某船闸工程设计规模1000 t级(Ⅲ级船闸),新建下游引航道穿过大坝下游农田和河漫滩,平均开挖深度约12 m,在施工过程中发生边坡失稳滑塌。通过对地质补充勘探资料的分析,找出边坡滑塌的主要原因。对多种处理方案进行对比分析,最终采取上部卸载下部压坡和地下连续墙综合处理技术,解决了引航道滑坡问题。
The design scale of a shiplock project was 1000t(Class III shiplock).The new downstream approach channel passes through the farmland and floodplain downstream of the dam,and the average excavation depth was about 12m.The slope was unstable and collapses during the construction.Through the analysis of geological supplementary exploration data,the main causes of slope collapse were figured out.Through the comparative analysis of various treatment schemes,the comprehensive treatment technology of upper unloading,lower slope pressing and underground continuous wall was adopted to solve the problem of approach channel landslide.
