    • Abstract
  • The tlexible retaining method with prestressed anchors for ultra-deep excavations in from rocky soil has obvious advantages: low cost, quickness, convenient in construction, great safety performance and good economic and social benefits. A detailed design for the flexible retaining method with prestressed anchors in the ultra-deep excavation of Yuanyang is introduced. The successful application of the design method provides guidance for the supports of ultra-deep excavations in rocky soil.
