In order to research the theory for variety of transverse forces adjacent shield tunnels caused by foundation pits excavation, effect mechanism pit excavation on tunnel was analyzed. The sidewall unloading model pit, considering deformation retaining structures, introduced calculate additional stress soil excavation. On this basis, confining pressure variation established, influence longitudina...

Day by day the call to solve traffic congestion problems is increasing. Subway tunnels and high-speed railway are commonly used for transportation. Therefore, tunnel construction induces soil movement, which in turn affects stability integrity of adjacent existing buildings. A series numerical simulations have been established investigate effects Greater Cairo Metro–Line 3-Phase-1 on pile cap f...

Newly formed somites or unsegmented paraxial mesoderm (UPM) have been cultured either in isolation or with adjacent structures to investigate the influence of these tissues on myogenic differentiation in mammals. The extent of differentiation was easily and accurately quantified by counting the number of beta-galactosidase-positive cells, since mesodermal tissues had been isolated from transgen...

Dimensional analysis is applied to study the pounding response of two inelastic multidegree freedom (MDOF) structures under simplified earthquake excitation. The forces and deformations collision processes are simulated by adopting improved Kelvin model. characteristics MDOF described bilinear interstory resistance model, representations dimensionless impact force motion equation in process der...
