摘要： This invention discloses a model test apparatus and method for shield post-wall grouting and tube sheet uplift under high water pressure conditions, comprising main body box, tension apparatus, shield system, grouting system, ground stress loading system, water injection system, and monitoring system. The main body box comprises the shield shell system and model soil inside. The ground stress loading system and water injection system realize the simulation of the complex underground soil and muddy water environment by applying stress and water pressure to the model soil inside the main box. While the tension apparatus makes the shield shell moving forward, the grouting system injects slurry into the gap between the shield shell and the tube sheet. The integrated model test of visual shield grouting and tube sheet uplift, the real-time multi-physical field responses, and the longitudinal deformation mechanism have been realized and revealed under high water pressure conditions.

摘要： A long-term in-situ observation device for the deep sea bottom supported engineering geological environment is provided, including: a sediment acoustic probe, a sediment pore water pressure probe, a three-dimensional resistivity probe, a water observation instrument, a long-term observation power supply system, a probe hydraulic penetration system, a general control and data storage transmission system, an acoustic releaser, an underwater acoustic communication apparatus, and an instrument platform. The observations include the engineering properties, physical properties, mechanical properties, and biochemical properties of a seawater-seabed interface-sediment. The engineering properties and the physical and mechanical indexes of seafloor sediments are comprehensively determined by three-dimensional measurement of seafloor resistivity and acoustic wave measurements. The physical and biochemical properties of seawater are expected to be acquired by sensors. The observation probe penetrates into the sediments following the hydraulic method.
