软土地基条件下斜腿刚构桥的设计体会

Experience in Design of Prestressed Concrete Slant Legged Rigid Frame Bridge under the Condition of Soft Soil Foundation

在软土地基条件下由于土基提供水平抗力不足造成斜腿结构开裂变形,影响结构使用安全和耐久性。论文以江门市东炮台桥扩建工程为实例,介绍预应力混凝土斜腿刚构桥设计中针对以上问题所采取的相应措施。

Under the condition of soft soil subgrade soil due to provide horizontal resistancecaused by lack of slant leg structure cracking deformation, affect structure safety and durability. This paper takes Jiangmen City East Fort bridge expansion project as an example, introduces the corresponding measures of prestressed concrete slant legged rigid frame bridge design in view of the above problems by adopting the.
