A　new　concept-settlement-based　design　for　pile　foundations　was　proposed,　which　offered　a　novel　alternative　to　solve　the　bump　problem　between　bridges　and　roads.　By　adjusting　pile　lengths　and　pile　numbers,　the　settlement　of　pile　foundation　increased　from　the　main　span　to　the　side　span　to　such　an　extent　that　it　matched　the　settlement　of　the　embankment　at　both　ends　of　bridges　without　any　special　treatment.　After　construction,　a　long-term　monitoring　program　on　bridge　piles　and　the　embankments　was　performed,　which　verified　the　practicability　and　efficiency　of　the　present　method　for　single　braced　bridges.　The　application　indicates　that　the　settlement-based　design　for　pile　foundations　could　greatly　reduce　the　total　costs　by　eliminating　the　necessity　of　soft　soil　treatment　at　embankments　and　decreasing　pile　lengths　and　pile　numbers.
