PLAXIS 2D REFERENCE MANUAL CHAPTER 5.8.10 SERIES

The prototype bridge abutment performed very well, showing highly integrated behavior with very high connection strength between the backfill and the parapet.Д«anting W.P. Results from field full-scale lateral loading tests on the abutment performed to ensure the design conditions are reported. The design, in comparison to that of the conventional-type bridge abutment, and the staged construction procedure of the prototype bridge abutment are described. It is shown that the compressive strength of cement-mixed gravely soil increases considerably with compacted dry density. It is shown that cement-mixed gravely soil should be mixed at the optimum water content for compaction energy used to construct the backfill.

Results from a series of drained triaxial compression tests on cement-mixed gravely soil are reported. A series of model shaking table tests were performed to evaluate the seismic stability of conventional-type bridge abutments as well as several new types of bridge abutments, including the one that was actually employed to construct the prototype. It is shown that the new type of bridge abutment is very cost-effective. This structure is very unique in that the backfill supports laterally the RC parapet rather than exerting static and dynamic earth pressure on the back face of the parapet as in the conventional-type bridge abutment, which consists of a relatively massive RC structure supporting the backfill of uncemented soil. The backfill and the parapet are firmly fixed to each other with geogrid layers embedded in the cement-mixed backfill. This chapter describes a new type of bridge abutment consisting of the backfill of geogrid-reinforced, cement-mixed gravely soil and a thin reinforced concrete (RC) parapet structure (i.e., a parapet) supporting a bridge girder, which was completed in 2003 for a new bullet train line in Kyushu, Japan.
