软土地区堆载对邻近高架桥墩的影响分析

摘要

In view of the Guangdong soft soil area,by using finite element method,the paper pres﹣ents study on the additional bending moment and deformation of viaduct pile caps caused by cumulative soil in Dongsha,GuangDong﹣Xinlian Highway project.The hight of the surcharge,the distance from piles of the surcharge,symmetricalsurcharge load have been analysed.Thensome effective engineering control﹣ling measures have been put forward on the influence of surcharge load on adjacent viaduct.%针对广东软土地区的土质，采用整体有限元方法，研究了堆土对广州东沙至新联高速公路高架桥梁承台桩基的附加弯矩和变形。考虑堆土高度，堆土距离，对称堆土对墩基的影响，提出了控制堆土对邻近桥梁承台影响的有效工程措施。
