The invention provides a method for forecast evaluation of the peripheral disturbance influence of foundation pit excavation. The method for the forecast evaluation of the peripheral disturbance influence of the foundation pit excavation comprises the steps that a basic displacement computational formula and a solving method of correction factors under the influence of various complicated conditions are established through a basic model under the base condition; parameters for the forecast evaluation of the disturbance states of the foundation pit excavation are foundation pit excavation peripheral displacement values (horizontal displacement values and vertical displacement values) and spatial distribution characteristics of the foundation pit excavation peripheral displacement values; the disturbance states of the foundation pit excavation are divided into six grades which are the disturbance-free grade, the micro-disturbance grade, the slight-disturbance grade, the medium-disturbance grade, the serious-disturbance grade and the dangerous-disturbance grade according to the displacement obtained according to the formula through calculation and the possibility and the serious degree of the influence which can be exerted on peripheral pipelines, and then evaluation parameters and an indicator system of the peripheral disturbance influence of the foundation pit excavation are established.
