In combination with the crushed rock slope as an example, the allocation of an anchorage force on longitudinal beams and transverse beams is calculated by adopting the distribution coefficient law of the nodal form at first. Then the internal forces of the lattice beam are calculated respectively through the software on the basis of Winkler elastic foundation model and the semi-infinite foundation model, and then compared with the internal forces which are based on simplified foundation pressure calculation. The active pressure of rock is calculated approximately by Ranking soil pressure theory in the working stage. Sequentially, the reinforcing bars are disposed by two-stage's averagely calculated values.

To the problem that the isotropy and the technological efficiency of the parallel kinematic machine based on Stewart platform are not satisfactory, a novel architecture of 6-DOF 3-dimensional platform parallel kinematic machine (6-DOF 3-D PPKM) based on the 2-2-2-SPS 3-D PPR is presented. The technological efficiency of design of the parallel kinematic machine is analyzed. Its workspace and the effect of design parameters to the workspace volume are studied. By using the submatrices of Jacobian matrix and force Jacobian matrix, the kinematics/mechanics transmission isotropic indices, kinematics transmission indices, load-bearing capacity indices at any configuration of the parallel kinematic machine are proposed, respectively.

The results show that the air crossing pressure pulse magnitude of the container generated in the tunnel is 3.46 times that generated in open air when container flat wagon at the speed of 160 km/h passed by EMU moving at the same speed. Both the lateral force and overturning moment of the container train during the crossing induced in open air and tunnel are approximately proportional to the square of running speed of the passing train. The pressure of crossing side and uncrossing side for the container flat wagon is almost equal since the one-dimensional characteristic of pressure distributing induced in the tunnel is not faintish. Consequently, the value of the lateral force and overturning moment of the container train generated in open air is greater than that generated in the tunnel, about 1.1 times.
