Abstract

Abstract

Using the numerical simulating technique, the limit loads with various parameters for strip footings near excavations are obtained. As accepted in other proposals, the estimate of the bearing capacity near an excavation is calculated here respectively from the terms dependent on the cohesion, the footing depth ( overburden) and the soil weight based on Terzaghi. s assumption of superposition. According to the stress and displacement filed simulated within the range of xcavation depths, it is found that potential critical sliding surfaces are allowed above-the-toe failures. And further, the characteristics of bearing capacity adjacent to excavations are discussed using the results that obtained in terms of the bearing capacity coefficients from numerical modeling.
