联锁块软体排深水沉排受力的线性有限元分析

长江南京以下12.5 m深水航道一期工程在狼山沙左缘的铺排工程中，遇到流速2 m/s及水深达30 m的沉排条件，使排体受力十分复杂。设计中通过对软体排沉排过程的受力状态进行有限元分析，提出了排体所受水流力的大小与移船距离的相对关系；通过分析深水铺排施工要点，优化排体设计方案。

Analysis of sinking force of concrete interlocking blocks in deepwater by linear finite element

The placing of concrete interlocking blocks at the left edge of Langshansha in the 12.5 m deepwater channel downstream Nanjing of the Yangtze River phase I project encountered a flow rate of 2 m/s and water depth of up to 30 m, which made the acting force of concrete interlocking blocks quite complicated. Based on the finite element analysis of the acting force on the concrete interlocking blocks, we point out the relationship between the current force and the moving distance of the ship. Based on the analysis of the key points of deepwater construction,we optimization the design scheme.
