The case studied in the paper proves that thickening the pile cap is an effective seismic retrofit alternative tostrengthen a pile group foundation. Unlike the typical seismic retrofitting of foundation, the proposed method eliminatesthe need to drive long piles into existing bridge substructures, substantially reducing cost, construction time and traffic interruption.The method thickens the pile cap of the bridge foundation to engage with a larger quantity of soil when underthe influence of seismic excitations. The additional friction provided by the surface of the concrete encasement helps toresist the overturning moment of the earthquake forces, while the passive pressure provided by the soil helps to resist lateralforces during earthquakes. The method is recommended for implementation in the freeway bridge retrofit project inTaiwan due to construction constraints. A successful retrofit requires existing piles in at least moderate condition, detailedconstruction sequences and installation of the encasement.
