| Abstract: | When tunnel traverses weak surrounding rock and fault cracked strip, it is easy to bring paroxysmal geological disaster in course of digging and it directly threatens the security of builders and equipments. For the engineering example of the first longest tunnel, the Baotashan tunnel in Shanxi province, the lining structure de- sign and construction prevention and cure measure when it traverses weak surrounding rock and fault cracked strip are introduced. Key technologies about the design and construction of advance curtain grouting are addressed, which can provide reference for analogous engineering＇s design and construction. |
