In this thesis we reviewed the Lorentz gauge theory of gravity that was introduced for gravitational interactions. In this theory the way of variation is based on Lorentz space components that is tangent to space time. Because of the metric does not depend on the components of the Lorentz space that is tangent to space time, so its variation is zero and does not have a dynamics. This is the beginning of many interesting features of this theory that aspires us to study it. We mention the description of the expansion of the universe without the need for dark energy and having the necessary condition for renormalizability. We have studied the field equations of this theory. This theory has an effective classical state, where its gravitational constant is equal to the constant of Newton's gravity. The cosmological solution of this theory describes de-Sitter space time without useing the cosmological constant, and explains the expansion of universe and spontaneous change from a negative to positive acceleration. In this theory, in addition to mass, spin of particles also produce gravity, which we have studied. This force, like the classical force of gravitation and electromagnetism, is a reverse squared distance and is directly related to spin of particles. We showed that Schwarzschild space time is the exact solution for the vacuum of this theory. This issue is important as experimental observations that are related to solar system can be explained useing the Schwartszchild solution of this theory. We also proved that Kerr space time is also an exact solution for the vacuum state of this theory, which can be used to describe problems related to rotating masses and also explain laboratory tests such as spin gyroscope deviation. We investigated the interaction of spin of quantum particles with the classical limit of gravitational fields in the Lorentz gauge theory of gravity.
