The faults produced by the deformation and motion of Earth’s crust are distributed on the geotechnical foundation engineering. The fault foundation includes the upper rock mass

lower rock mass and the structure surface. It is necessary that the properties of rock mass

structural surface

deposit history

and structure function are considered in design of building. The principles of design and construction are excavation from ground

non-disturbing

increasing strength

anti-seepage and draining freely. The fault is reinforced by some effective measures including filling

arching

lining

settling well

supporting with column and pile

anchor and so on.
