前 言 船闸的闸首边墩,为一外形轮廓不规则的空间块体结构,承受的荷载也很复杂,既受到平行于船闸轴线方向的纵向荷载作用,又受到垂直于船闸轴线方向的横向荷载和竖向荷载的作用,边墩局部范围尚受有巨大的闸门集中推力的作用。因此,闸首边墩结构,无论是从它的几何特性,还是从它的受力条件来看,实际上,是属于空间性质的问题。目前,尚无精确的理论解。 Foreword The lock head pier is an irregularly shaped space block structure with a complicated load bearing capacity. It is subjected to both longitudinal loads parallel to the axis of the ship lock and transverse loads perpendicular to the axis of the ship lock. The role of vertical load, while the local boundary pier is still subject to a huge gate focus on the role of thrust. Therefore, the structure of the gate head piers is, in fact, a matter of space nature, no matter from its geometric characteristics or from its stress conditions. At present, there is no accurate theoretical solution.
