| 摘 要： | 对高桩码头重力式挡土墙接岸结构的岸坡,采用有限元强度折减法,分别针对挡土墙前后土体高差、岸坡坡肩宽度、岸坡坡比等因素对岸坡尺寸进行了优化。结果表明,合理增加挡土墙前后土体高差,并在保证岸坡稳定的前提下,适当的减小岸坡坡肩宽度、增大岸坡坡比,可以有效减小后方承台的宽度,从而达到节省工程投资的目的。

| Abstract: | In this paper,aiming at gravity retaining wall shore-connecting structures,bank scales including the height difference of retaining wall,slope shoulder width and slope ratio were optimized by the strength reduction FEM with finite element software the PLAXIS.The results show that,in the premise of protecting slope stability,the measures to save construction investment are increasing the height difference of retaining wall,reducing slope shoulder width and increasing slope ratio to reduce the width of the pile platform. |
