Weak surrounding rock is a difficult part in tunnel construction.It has the characteristics of low strength,poor stability,and long duration.In construction,tunnel collapse and surface subsidence are likely to occur.According to the geological conditions,it is important to choose a reasonable construction plan and implement dynamic control in the course of construction combined with Geological forecast and monitoring measurement.In this paper,the construction of weak surrounding rock is analyzed and discussed in the light of the concrete construction of a high speed rail tunnel.
