摘　　要：提出船闸引航道内水面波动的二维数学模型,采用二维非恒定流数学模型和船闸灌泄水一维数学模型联解.这一模型考虑了船闸灌泄时水流惯性的影响,较好地模拟了三峡工程上引航道船闸灌水产生的水面波动,同时,给出了水面波动周期和波长的近似计算公式。A 2-D numerical model of wave motion in lock approach channel is described, which is soluted by using the method of resultants of 2-D numerical model of unsteady flow and 1-D numerical model. It considers flow inertia during the lock filling and emptying and simulates the wave motion during lock filling and emptying in the approach channel at the upper reach of the Three 桮orge Project. And finally, the approximate expressions of period and length of waves are presented.
