Analysis on Ultimate Bearing Capacity of Rock Foundation

Hou Da-wei

Abstract

Many high-risie buildings are based on rock foundation in mountainous city,so how to evaluate the bearing capacity of rock foundation is the core for rock foundation engineering.In view of the influence of central major stress and lithology and rock structure characteristics on rock foundation bearing capacity,this paper equates jointing rock with discontinuous medium characteristics to continuous medium,and then seeks for solution with instant friction angle and slip-line field theory.It establishes analysis model for ultimate bearing capacity of rock foundation and verifies feasibility of the model through calculation.
