Abstract：
Aiming at the deficiencies exist in the traditional working face supporting method with filter cake, this paper introduced a new material for the auxiliary construction of shield, i.e. the Paste HDN and its engineering characteristics, proposed a new working face supporting method with this material during hyperbaric intervention, and analyzed relevant cases under the complex conditions like water-rich sand stratum, fractured rock stratum, cobble stratum, soft upper and hard lower mixed stratum, etc. The results show that this new method simplifies the preparation procedure of filter cake, produces a filter cake with sound durability and sealing, ensuring the intervention safety in shield chamber and improving the construction efficiency.
