前言:随着桥梁建设的新发展、桥梁下部构造大大跟不上形势的要求,上部构造采用新材料和新工艺、结构设计和计算进一步得到改善,而桥墩和桥台迄今仍保持它旧有的形式和结构。由于结构形式不合理,采用高质量材料,强度也大大不能满足。桥台结构出现缺点多半是;填土沉陷、浸水、冻裂损害以及过大的倾斜。 Preface: With the new development of bridge construction, the structure of the lower part of the bridge is far behind the requirements of the situation. The new structure and design of the superstructure are further improved by adopting new materials and new techniques. However, the piers and abutments still maintain their old Form and structure. Due to the irrational structure, high-quality materials, the strength is also greatly unable to meet. Bridge abutment structure defects are mostly; fill subsidence, flooding, cracking damage and excessive tilt.
