Abstract Research purposes: According to the difficulties in construction of weak enriched water surrounding rock grade VI Jiangmen Tunnel，the suitable advance reinforcement mode and tunnel excavation method were chosen． in order to ensure construction safety and road operation safety．
Research conclusions: ( 1) The horizontal churning jet pile was used for the advance reinforcement，and the large pipe roof in advance and CRD method were used for excavation to safeguard the tunnel under － passing the road． ( 2) With the finite element calculation software，the numerical simulation was made for the whole process of the tunnel excavation，the analysis was made for change trends of the stress and displacement of the surrounding rocks during excavation to decide the key points of the construction control and monitoring ground deformation． ( 3) The steel frame needed to be enclosed in time for a loop to prevent appearance of large displacement and floor swell．
