Abstract:

A deep pond section of a city expressway with small interval parallel to the Beijing-Shanghai High-Speed Railway was taken as engineering background. The impact of traditional high embankment on the Beijing-Shanghai High-Speed Railway was analyzed by numerical method from the following four aspects: horizontal displacement and settlement of bridge piers, axial force and skin friction of piles. The results indicated that horizontal displacement of the Beijing-Shanghai High-speed Railway caused by high embankment was far more than the limit, which would cause serious damage to its viaduct. So a spanning technology using low bridges was put forward, which included pre-stressed concrete slab beam, continuous bridge deck erected as simple-supported, gravity abutment, bored pile foundation and 4 m pier. Displacement caused by the low bridge was far less than the limit value. This technology would not affect the normal operation of the Beijing-Shanghai High-speed Railway. Subsequent monitoring results also showed that the low bridge was a reliable technology to spanning deep pond with small interval paralleling to high-speed railway.

Key words: road engineering, spanning technology by low bridge, Beijing-Shanghai High Speed Railway, nearby paralleling, high embankment
