摘　　要：为了充分保障道路出行的安全性,应对桥隧过渡段针对性地采取处置措施。论文从设计及施工方案不合理、桥台压实度不足、结构沉降量差异等路基路面出现沉降的原因入手,对过渡段路基路面设计要点及沉降处置措施进行了重点分析。并以某市政快速路为例,对高压喷射注浆法的沉降处理措施进行了验证。In order to fully ensure the safety of road travel,targeted treatment measures should be taken for bridge tunnel transition sections.This article starts with the reasons for the settlement of roadbed and pavement,such as unreasonable design and construction plans,insufficient compaction of bridge piers,and differences in structural settlement.It focuses on the key points of roadbed and pavement design and settlement treatment measures in the transition section.And taking a certain highway as an example,the settlement treatment measures of high-pressure jet grouting method were verified.
