摘　　要：本文从改造工程概况、闸底板结构计算、闸室稳定计算三个方面对张巷浜节制闸改造中的结构计算进行分析。根据单宽板条平衡条件,推求不平衡剪力;依据剪力分布,采用积分法确定闸墩和底板剪力分配系数。针对性计算均布荷载、集中荷载、边荷载,核定闸室底板弯矩。依据《水闸设计规范》(SL 265—2001)要求,确定闸室稳定计算条件,列举地基应力、应力不均匀系数、闸室抗滑稳定系数、闸室抗浮稳定系数等计算方法。本文论证了节制闸改造工程的典型计算方法,阐明了计算过程,以期为类似节制闸改造提供借鉴。In the paper, the structure calculation in Zhangxiangbang regulator renovation is analyzed from three asj）ects ofrenovation project profile, sluice board structure calculation and gate chamber stability calculation. The unbalanced shearforce is deduced according to the balance condition of single width plate. Integral method is adopted for determining the gate pier and bottom board shear distribution coefficient according to shear force distribution. The uniformly distributed load, centralized load and lateral load are calculated in a targeted mode. Gate chamber bottom board bending mThe gate chamber stability calculation conditions are determined according to requirements of $ Water Gate Design Specification % ＆ SL 265-2001 ）. The calculation methods are listed, such as foundation stress, stress non-uniform coefficient, gate chamber anti-slip stability coefficient, gate chamber anti-floating stability coefficient and other calculation method. In the paper, the typical calculation method of sluice renovation project is discussedclarified, thereby providing reference for similar regulator reform.
