Abstract

Abstract: At steep mountainous area，to avoid the serious damage of the ecological environment in road widening and reconstruction， a kind of half-bridge and slope base composite embankment structure was proposed，which consisted of the reinforced concrete frame structure leaning upon the inner road embankment and superstructure for traffic． By establishing the spatial FFM entity model of half-bridge and slope base composite embankment structure，the force transmission mechanism of this kind of structure under the loading was investigated． And the mechanical behavior of composite structure under different geological conditions were also studied．Ｒesults show that when the half-bridge and slope base composite embankment structure strengthens the lateral road， the inner slope is also strengthened at the same time．

Key words: half-bridge and slope base composite embankment, spatial analysis, geological conditions, local softened base

摘要： 在陡峻山区道路拓宽改造中，为避免高填深挖造成生态环境严重破坏，提出用钢筋混凝土框架结构强化已有道路路堤，并以此为基础加宽道路形成半桥-边坡复合道路结构。采用空间有限元建立实体模型，分析了半桥-边坡复合道路结构在荷载作用下的传力机理，及不同地质条件对复合道路结构力学性能的影响。研究表明:复合道路结构在对外侧道路加宽的同时，对内侧边坡起到加强效应。
