松花江依兰航电枢纽冰荷载计算方法研究

Study on calculation method of ice load on Yilan Navigation and Hydropower Project on Songhuajiang River

松花江依兰航电枢纽的主泄洪闸闸墩和引航导堤堤头都是流冰冰排主要作用的结构或部位,将其作为计算对象,用国内外有关计算公式对其承受的冰荷载进行初步校核,并比较所搜集的冰荷载计算公式对当前枢纽工程结构的适用性,选择出适于松花江冰情特点的计算公式。

So far as Yilan Navigation and Hydropower Project on Songhuajiang River is concerned, the piers of the main flood discharge sluice and the head of the training dyke for the approach channel of the ship lock are the structures and locations mainly forced by the pack of the drift ice therein; which are taken as the calculation object, the ice loads on them are preliminarily checked herein with the related formulae at home and abroad, and then the formula suitable for the feature of the ice regime of Songhuajiang River is found out in accordance with the comparison of the applicabilities of all the collected formulae for the calculation of the ice loads to the engineering structures of the project concerned.
