In the construction of Xiamen Xiang\'an tunnel,peripheral curtain grouting,advance long pipe-roofing and tri-bench excavation method have been taken based on the geological condition of deep F3 weathered trough passed by Xiang\'an tunnel.

Application of large curtain grouting technology for water control in Yagongtang Mine Area of Shuikoushan Lead-zinc Mine;

The numerical simulation analysis of the building curtain grouting reinforcement effect;

Construction technology of curtain grouting for high pressure and rich water zone treatment in 0# transverse gallery of one tunnel;

Based on the engineering practice and a series of methods including theoretical analysis, laboratory tests, site observation and numerical simulation, the retention mechanism and anti-seepaging capability of clay-solidified grouting curtain (CSGC) to leachate are systematically researched and the environmental effects of CSGC applied in MSW landfill is completely eval.

Curtain grouting method was adopted in passing the fractured belt,with eight curtain holes,756.

The technique combined the pipe roof technic and curtain grouting method and assured the tunneling safety.

For the stability analysis of grouting water proof wall,the seepage permeability of limestone grouting wall system was tested,the overall process of seepage of the limestone grouting wall system is obtained.
