摘　　要：结合江苏省土基上的船闸工程实例，分析分缝施工的坞式结构底板的受力情况，就闸首计算中自重折减系数进行探讨，并对底板底层钢筋保护层在施工宽缝周围的防裂问题提出建议。Combining ship-lock engineering examples on soil foundation of Jiangsu Province, it analyses force acted on the bottom plate of castle structure with temporary construction joints. It also carries out investigation and discussion on the discount coefficie nts of deadweight in calculation of lock head, and puts forward suggestions on how to prevent cracks around the temporary construction joints of the protection layer for reinforc ed steel bars at the bottom plate.
