软基上高速铁路路桥过渡段的技术措施研究

Study on Technical Measures of the Soft-foundation in the Transition Section from Road to Bridge for Express Railway

摘要:

通过对高速铁路路基与桥梁过渡段动力特性分析 ,指出结构物沉降差是导致轨面不平顺的主要因素。分析了沉降差产生的原因 ,提出了软基上路桥过渡段的结构设计方案 ,并对其施工方法及质量检测标准进行了探索

Abstract:

Main reasons, of which settlement differences of structure materials lead to uneven rail surface, were pointed out through dynamical characteristic analysis of express railway foundation of the transition section from road to bridge. The reasons of settlement differences were analyzed and design program of soft foundation of the transition section from road to bridge was presented. The measures and quality inspection standards also were discussed.
