Based on practical engineering, considering the characteristics of unsymmetrical loading, shallow burying, and weak surrounding rock tunnel, MIDAS finite element software is adopted to analyze influence effect deformation a temporary steel support when tunnel excavated by two-step center diaphragm method (CDM). The simulation results are compared with field monitoring results. It can be seen th...

LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...
