When I run the command to simulate it works but only show a 10V steady value on the output in both start and end of transmission line. I'd like to see the transient values. Can anyone point me what I have done wrong?
You have used a fixed voltage source, which will have 10v output at t=0. LTSpice uses this to initialise the line and capacitor, then the simulation runs.
You need to use a source that starts at zero, then transitions to 10v a little after t=0. A PWL source will do, or the simpler pulse generator.
As others have said you had best use a pulse voltage source rather than a DC source because PSPICE, by default, solves for the steady-state solution before starting the simulation. However if you tell it not to do that, you can get it to work:
"Sort of work".
Compare the pulse with 10ns rise time below.
To get the fancier voltage sources, right click on the voltage source, and then click on 'advanced' to get the other options.
