摘要
针对成都地铁富水砂卵石地层中盾构施工渣土改良进行了室内试验研究,初步得出适合于该地层渣土改良剂的种类和配比,并通过现场应用确定砂卵石地层盾构施工渣土改良的合理配比,为其他类似地层盾构施工渣土改良提供一种参考。
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.
