My complete post included ..."  For long runs it is advisable to not run it 
perfectly straight, to allow for any small amount of movement...." to account 
for ground movement, in addition to thermal expansion/contraction, typically 
"snaking" the conduit runs to allow for all movement. If one is burying 
conduits in expansive clay soils, PVC conduit would not be a good choice for 
direct burial, as the pressure exerted on it from soil/clay expansion can crush 
it, making rigid steel conduit or precast concrete conduits a better choice, if 
one does not want to encase the PVC in concrete.

 Thermally induced expansion and contraction is not the only effect to 
consider.  Expansive soil will expand and contract with variations in soil 
moisture independent of temperature....
