沼泽区域在东非地区分布广泛,其软弱性土质对公路的路基路面,桥涵结构物都带来了不同的危害。桥梁桩长较长,施工困难等因素使这种地区的公路设计施工人员感到棘手。因此,沼泽区内桥梁下部结构的设计就成为了设计中的重点和难点。该文以乌干达KE项目Nambigirwa沼泽桥为背景,介绍了沼泽区域软弱土地区桥梁桩基础的设计和施工,为今后在乌干达等东非地区沼泽湿地桥梁基础设计及施工提供参考依据。 The swamp area is widely distributed in East Africa. Its weak soil brings different hazards to the subgrade and bridge-culvert structures of the highway. Long bridge length, construction difficulties and other factors make the highway design and construction workers in this area is tricky. Therefore, the design of the substructure of the bridge in the swamp area has become the focus and difficulty in the design. Based on the Nambigirwa marsh bridge of KE Project in Uganda, this paper introduces the design and construction of bridge pile foundation in the soft soil area of ​​swamp area, and provides reference for future design and construction of bridge foundation in marsh wetlands in Uganda and other East Africa.
