In contrast to straight tunnels, the mechanisms of displacement surrounding soil induced by shield excavation small radius curved tunnels are more complex. Based on field monitoring data surface settlement and horizontal a tunnel in section Zhengzhou Metro Line 3, numerical model using three-dimensional finite element method is established evaluate factors soil. The results verify validity simu...

The construction scale of the shield tunnel underpass is expanding day by day. In order to study safety influence and deformation control on existing tunnel, LSSVM model established. Based collected soil storage pressure, foam volume, simultaneous grouting volume other six parameters corresponding sample data bottom displacement, horizontal displacement settlement caused approach are predicted....

The neutronics activities for SPPS included the determination of the blanket dimensions that provide tritium self-sufficiency, radiation damage to the structural materials, lifetime of the in-vessel components, radiation level at the superconducting magnets, and shielding requirements for magnet protection. The neutron wall loading varies in both poloidal and toroidal directions. For an average...

BACKGROUND It is important to understand the anatomical relationship between the medial and lateral branches of superficial radial nerve (SRN) and the first dorsal compartment to prevent and minimize possible injury to these nerves during various procedures around the tip of radial styloid process (RSP). OBJECTIVE To delineate the anatomical location of the SRN in relation to the extensor pol...
