Finite Element Analysis of the Stability of Reinforced Shotcrete and Bolting Support of Deep Construction Pit of Silty Soil

摘要

This paper analyses the stability of reinforced shotcrete and bolting support of deep construction pit of silty soil with finite element method, inquires into the characteristic of its deformation, and finds that the primary physics-mechanics parameters of media effecting on the stability of the support are coherent c and modulus of elasticity E, and that the main engineering factor effecting on the stability of the support is anchor. Some suggestions based on the stability analysis are presented to the engineering construction, and this paper provides a reference to the design scheme.
