| Abstract: | Indoor experimental study is made on the ground conditioning for EPB shield in water-rich cobble ground in Chengdu and ground conditioning agents and their mixing proportions suitable for such ground are obtained temporarily.The agents and their mixing proportions are trialed in the job site and final appropriate mixing proportions are determined.The study results can be served as reference for the ground conditioning of EPB shields in other similar grounds. |
