针对塔贝拉水电站四期扩建工程中长直腹式钢板桩存在长度方向刚度低、吊运困难等问题，对本工程中长达36 m的直腹式钢板桩，利用工程现场易于获取的型钢，研发了直腹式钢板桩平吊的专用吊具。通过极限荷载情况下的吊具强度分析和钢板桩吊运时的吊具刚度及强度校核，说明吊具符合结构安全要求。工程实践说明，该吊具不仅保证了钢板桩的吊运安全，而且提高了吊运机动性，节省了吊运成本。

In the construction of the 4th phase extension project of Tarbela Hydropower Station, difficulties are encoun-tered in the lifting of the long straight-web steel sheet pile which is of a low stiffness in its longitudinal direction.A spe-cial beam-type lifting gear is designed for these 36m long steel sheet piles.It is made by profiled steel that is easily ac-cessible in construction site.Analyses on the strength of the lifting gear under its ultimate load and its strength and rigid-ity when lifting the steel sheet piles show that the structural safety requirement is satisfied.Practice shows that the de-signed lifting gear not only ensures the safety of the lifting process, but also improves the efficiency and saves the cost.
