Analysis on Factors Affecting Height of Equal Settlement Section in Pile-supported Reinforced Embankment
摘要
Abstract
Based on the pile-supported reinforced embankment project along Taizhou-Jinyun Highway, a 3D numerical model thereof is established with finite difference software FLAC3D so as to study how clear spacing of pile cap, internal friction angle of embankment fill, cohesion of the fill and tensile strength of horizontal reinforcement affect height of equal settlement section. The results show that ratio of the equal settlement section height to the clear spacing is 3.0 -3.7; and as the internal friction angle increases, this height decreases; however, the cohesion and the tensile strength have no influence on this height.关键词
