  The generalization of the Randall-Sundrum solution for the warp factor
exp[sigma(y)] in the scenario with one extra coordinate y, non-factorizable
space-time geometry and two branes isobtained. It is shown that the function
obtained sigma(y) is symmetric with respect to an interchange of two branes. It
also obeys the orbifold symmetry y -> - y and explicitly reproduces jumps of
its derivative on both branes. This solution is defined by the
Einstein-Hilbert's equations up to a constant C. It is demonstrated that
different values of C results in theories with quite different spectra of the
Kaluza-Klein gravitons.
