摘要 为了估算泥沙淤积对弧形钢闸门启门力的影响,提出了一个计算公式.该公式将门前淤泥考虑为由粗细颗粒组成的宾汉体,同时考虑了泥沙附着力的力矩、梁格中附带泥沙重力的力矩、转动铰摩阻力的力矩、止水摩擦力矩、下吸力的力矩以及闸门重力和外加重力的力矩对弧形钢闸门启门力的影响.并利用该公式计算的弧形钢闸门启门力和西洱河二、四级电站泄洪闸门的实测资料进行对比得出:在门前泥沙淤积厚度较低的情况下,弧形钢闸门的启门力矩主要由闸门重力和外加重力决定,但是由泥沙引起的启门力矩变化也是不容忽视的,是导致闸门开启困难的影响因素之一,因此在设计过程中应充分考虑泥沙淤积对闸门启门力的影响,制定出合理的操作和维护方案,以防止闸门启闭困难情况的出现;该公式在计算门前有泥沙淤积情况下的启门力时,其计算精度能够满足工程实际需要.

Abstract: In order to estimate the effect of silt sediment on the lifting force of steel radial gate, a calculating formula was proposed. In the formula, the silt deposited in front of the gate was considered to be the Bingham material which consists of coarse and fine particles. Also, the torques due to grillage sediment weight, rotational hinge friction resistance, seal friction resistance, undersuction effect, door weight and additionalweight were torque etc were involved in the formula. The lifting forces applying on the sluicing steel radial gates in the 2nd and 4th HydroPower Station on the River Xi′er were estimated and compared with those measured in the stations. It was shown that in the case of less sediment deposition, the opening and closing torque on a radial gate is mainly decided by the door and additionalweight, but the lifting force caused from the sediment cannot be ignored. It is the sediment that leads to there is a difficulty in opening gate, thus it should be fully taken into account in the gate design and propose a reasonable operation and maintenance plan for the gate to prevent the event that the gate cannot be opened or closed properly. The accuracy of the calculation formula can meet the needs of engineering practice when it is used to calculate the lifting force of a radial gate with deposited silt in front of it.
